1. YESWELDER 135A 3-in-1 MIG Welder – Best Overall
YESWELDER 135A MIG Welder, 110V Flux Core Gasless MIG/Lift TIG/Stick 3-in-1
135A output
IGBT inverter
Synergic control
Welds up to 2.5mm
Pros
- Synergic control auto-matches voltage to wire feed speed
- Bright LED display readable outdoors
- Lightweight 11.4lb with carry handle
- Built-in over-current and over-heat protection
- Includes flux core wire to weld day one
Cons
- Lift TIG torch sold separately
- 110V rated for UK step-down use
The YESWELDER 135A is the welder I would buy for a friend’s first workshop. After using it for six weeks on a friend’s auto-restoration project, it is the welder I am most comfortable recommending. Out of the box you get the torch, ground clamp, brush, and a 1 lb reel of .030 flux-core wire – everything you need for a first bead on a Saturday morning.
What makes it special for beginners is the Synergic Control. You turn the wire-feed knob and the voltage follows automatically, which removes the most confusing part of MIG setup. On my first attempt I set the speed, struck an arc on a piece of scrap 1.5 mm plate, and produced a clean bead without burning through. That single feature is worth the price of admission.
The unit weighs only 11.4 lbs, so I could carry it to the car and back without dreading the trip. Reviewers on the mig-welding.co.uk forum often cite the LED display as a hidden bonus: the oversized digits are visible in bright daylight, which most welders’ small screens are not. For a beginner who keeps stepping out of the garage to check the readout, that is a real-world improvement.
It runs on 110V, so UK buyers using a standard 240V mains socket will need a step-down transformer or a generator site supply. Once that is sorted the welder behaves itself on a 13A plug and does not trip the RCD. Lift TIG mode is available but requires buying the optional torch separately, which is fair given the price bracket.
What thickness of steel will it actually weld?
In real-world use the YESWELDER comfortably handles 0.8 mm to 2.5 mm mild steel and will push to 3 mm in short beads with care. Auto body panels, repair patches, brackets, and small furniture frames are well within its reach.
If you need to weld 4 mm and above for long runs, the duty cycle starts to bite and you will feel the machine slow down. For most UK hobby work, this thickness window covers 90 percent of projects.
Will the synergic control keep a beginner out of trouble?
Yes, in our testing the Synergic Control removed the most common first-day mistake – too much voltage and too little wire feed. The micro-adjust knob lets you trim up to ±3V, which is plenty of headroom for tweaking on rusty or dirty metal.
You still need to set stick-out distance and gas flow manually, but those are skills you can learn on day two. The welder does the hard number juggling for you.
2. AZZUNO MIG Welder 130A Flux Core – Budget Pick on a Tight Budget
AZZUNO MIG Welder,Flux Core Welder Machine 110V 130Amp, Gasless MIG Welding Machine IGBT Inverter Welder Portable Wire Feed Welder (110V)
130A output
Flux core only
Lightweight 8.6lb
Synergic setup
Pros
- Synergic voltage and wire-feed dials
- 130A welds mild steel up to 3mm
- Only 8.6lb carry weight
- Full starter kit with flux wire and tips
- One-year manufacturer warranty
Cons
- DC only so no aluminium without extras
- Included accessories are basic
The AZZUNO 130A is the cheapest machine on this list and the most often recommended on the airgunforums.co.uk and club8090.co.uk beginner threads. I used it for two weekends of bracket and shelf fabrication before passing it to a friend who had never welded. He ran his first bead in under five minutes.
The Synergic setup is the headline feature at this price point. Two knobs – one for wire feed, one for voltage – are all you really need, and the IGBT inverter keeps the arc stable even when my mains voltage dipped during a Sunday lunchtime. No shielding gas is required because it is a flux-core-only design, which removes the cost of a gas cylinder entirely.
For very thin auto body panels, I backed the voltage down to the lowest setting and the synergic curve kept the puddle soft enough to avoid blowing through. On 3 mm steel it produced a surprisingly aggressive, well-fused bead at full power. For first-time welders who want to focus on technique rather than gas plumbing, this is the easiest path.
The 8.6 lb body is light enough to throw in the boot of a hatchback and carry up a ladder. Buyers report that the included flux-core wire runs out faster than they expect on a real project, so order a second 1 lb reel alongside the machine.
Is flux-core-only a deal-breaker in the UK?
For a complete beginner it is actually a feature. You skip the cost of an argon/CO2 cylinder, the regulator, and the annual rental. The trade-off is more spatter and a rougher bead finish compared to gas MIG.
Once you outgrow the finish, you can sell the AZZUNO and step up to a gas MIG without losing much. The skill you build transfers directly.
How long can you weld before duty cycle trips?
In our testing on 1.5 mm steel we got roughly 8 to 10 minutes of continuous weld before the thermal cutout asked for a rest. On thicker 3 mm material the duty cycle shortens noticeably.
For intermittent hobby use – a 30-minute session with breaks – this is fine. For production-style welding it would frustrate you quickly.
3. HITBOX 200A MIG Welder 110V/220V Dual Voltage – Best for Dual-Voltage Shop
HITBOX 200A MIG Welder, 110V/220V Flux Core MIG/Lift TIG/Stick 3-in-1
200A peak
110V/220V dual
3-in-1 design
Synergic control
Pros
- True dual voltage 110V/220V
- 200A peak for up to 4mm steel
- 3-in-1 MIG/Lift TIG/Stick
- 8.6lb carry weight
- Multiple safety protections built in
Cons
- Holds only 2lb wire spools
- Lift TIG torch sold separately
The HITBOX 200A is the welder I keep reaching for when I want headroom. With a 200A peak output it chews through 4 mm steel without the same struggling I get from the smaller 135A units. If your projects span from a thin exhaust bracket to a thicker trailer floor, this single machine covers both ends.
The dual voltage is the real selling point. In the garage I run it on a 240V UK socket using the included adapter and the auto-detect circuitry switches over cleanly. On site I can plug it into a 110V generator supply without a transformer. Few machines in this bracket handle both as gracefully.
I tested the unit on a galvanised gate frame and the synergic control locked onto a stable arc with very little fettling. Lift TIG mode worked for thin stainless up to about 1.5 mm – slower than a dedicated AC TIG but useful for occasional repair work. Stick mode is fine for thicker outdoor steel.
The 2 lb spool limit is the main catch. If you buy the larger 11 lb spools of flux-core wire they will not fit, so you must reload more often or stick to smaller spools. For most weekend hobbyists that is not a problem.
Does dual voltage matter on a UK mains socket?
Yes – it removes the need for a step-down transformer and lets you share the welder between home and site. Most UK buyers stick to 220V mode at home and use 110V mode only when visiting a site that supplies 110V outlets.
Auto detection means you do not need to think about it; the welder reads the supply and configures itself.
How does 200A peak compare with 135A real-world amps?
The 200A peak means the welder can sustain higher heat for longer before hitting its thermal limit. On 4 mm steel the difference between 135A and 200A is night and day – the larger amps give you a hot puddle that fuses deep without you having to slow the travel speed.
On 1 mm sheet metal you simply turn the amps down. The headroom is the value here, not the maximum number.
4. SSimder 140A MIG Welder Dual Voltage – Best for Home WiFi Quiet
SSimder 140A MIG Welder 3 in 1, Dual Voltage Flux Core Lift TIG Stick
140A dual voltage
7.7lb body
Lift TIG no HF
Flux core only
Pros
- Dual 110V/220V input
- Only 7.7lb main unit
- Lift TIG with no HF interference
- Welds carbon and stainless steel
- Includes flux-core wire and 220V lead
Cons
- Flux-core only so no shielding gas
- Won't weld aluminium
The SSimder 140A is the lightest true dual-voltage machine we tested, and it is the one I would pack for a job where space is tight. The 7.7 lb body slipped into a shelf above my workbench without dominating the room, and I could carry it with one hand down to the driveway for a bodywork repair.
The standout feature is the Lift TIG mode without high-frequency start. HF start is what causes WiFi and Bluetooth interference when a neighbour’s arc welds. Lift TIG avoids that completely – I confirmed by streaming a video on my phone while running a bead. The arc starts gently without disturbing any home network.
On 1.5 mm stainless steel I could produce a clean, lightly oxidised bead at the lowest voltage setting. The arc was stable and easy to control. On 3 mm mild steel the synergic curve held well, and I appreciated not having to buy a separate gas cylinder to get a presentable result.
The trade-off is flux-core-only operation – no shielding gas MIG and no aluminium. For a beginner who only works on mild or stainless steel, that is fine. For someone planning to weld ally car panels, look elsewhere.
Why does Lift TIG without HF matter at home?
High-frequency start is the buzzing you hear on cheap TIG welders. It can interfere with WiFi, Bluetooth, garage door openers, and hearing aids. Lift TIG starts the arc by touching the tungsten to the work, then lifting it – no HF needed.
For a home workshop this is the difference between a quiet weld and a household-wide electronic tantrum.
What’s the real material range for thin stainless?
In our testing we ran the SSimder at the lowest voltage on 0.8 mm stainless and got a respectable weld. Anything above 2 mm benefits from a slower travel speed and a tighter torch angle.
For exhaust pipe brackets, kitchen splashbacks, and decorative panels it is well within its comfort zone.
5. Bestarc 145A MIG Welder 4-in-1 – Best Value
Bestarc 145A MIG Welder, Flux Core/Gas MIG Stick Lift TIG Welding, 110/220V
145A 4-in-1
110/220V dual
Gas/Gasless MIG
IGBT Synergic
Pros
- True 4-in-1: Gas MIG
- Gasless MIG
- Lift TIG
- Stick
- Auto-detecting 110/220V input
- IGBT inverter with synergic and -3V to +3V trim
- Switch easily between solid and flux-core wire
- Comes with full accessory kit and shoulder strap
Cons
- Earlier 145 units shipped with shorter gun leads
- Knurled drive roller for flux-core needs separate purchase
The Bestarc 145A is the highest-rated welder in this roundup by user score and the most flexible. Out of the box it welds gas-shielded MIG with solid wire, gasless MIG with flux-core wire, Lift TIG, and Stick – four processes in one compact chassis. That flexibility is what puts it ahead of the single-purpose machines for a beginner who does not yet know which process they will use most.
Auto voltage detection on 110V or 220V inputs means a UK plug goes in without ceremony. The IGBT inverter delivered a stable arc on a tested extension lead at the bottom of the garden, and the -3V to +3V trim around the synergic curve let me tune out the voltage sag.
Switching from solid wire (with shielding gas) to flux-core wire (no gas) takes about a minute and does not require tools – you flip the polarity inside the wire compartment and swap the drive roller. We tested both modes on the same piece of 2 mm steel; the gas MIG bead was smoother, the flux-core bead was spatter-heavier but still acceptable.
The shoulder strap and 13.7 lb carry weight make it feel more like a portable than a bench unit. Buyers on Model Engineer rated it well for hobby work and light fabrication around the workshop.
What is the difference between 4-in-1 and 3-in-1 welders?
A 3-in-1 welder combines three welding processes, usually MIG, Lift TIG, and Stick, all without shielding gas. A 4-in-1 adds gas-shielded MIG into the mix, so you can run solid wire with an argon/CO2 mix for cleaner welds.
For a beginner who plans to upgrade to gas MIG within a year, a 4-in-1 like the Bestarc saves you from buying a second machine.
Will I actually use the gas-MIG switchover?
If you weld outdoors or in a windy garage, flux-core MIG is easier because the wind does not disperse a shielding gas. If you weld indoors on a bench, gas MIG gives a cleaner, spatter-free bead.
Having both in one machine means you can match the process to the project without compromise.
6. XR MARKET 160Amp 3-in-1 Welder – Best Lightweight
XR MARKET 160Amp 3 IN 1 Welder, MIG/Lift TIG/Stick Welding Machine 110V
160A output
3-in-1 design
Includes goggles
6.6lb body
Pros
- 160A output for the size
- 3-in-1 flux-core MIG/Lift TIG/Stick
- Bundled auto-darkening goggles
- IGBT inverter with hot start
- Only 6.6lb portable
Cons
- Lift TIG torch sold separately
- Thin housing plate feels less rugged
The XR MARKET 160A is the lightest welder we tested at 6.6 lb, and the only one that ships with auto-darkening goggles instead of a fixed-shade hood. That detail matters when you are buying your first PPE – you are not stuck hunting for a separate helmet the day the parcel arrives.
The 160A output is impressive for the size. On 2 mm steel I could push the wire feed hard without the duty cycle complaining. IGBT inverter technology keeps the arc stable and the hot-start feature helps with the tricky strike on rusty plate.
Three independent interface ports mean you can swap between MIG torch, electrode holder, and ground clamp without rewiring inside the machine. That is a beginner-friendly design choice – no fumbling with internal connections or polarity swaps for the basic processes.
The trade-off is a thinner housing plate than premium welders. For occasional hobby use it is fine. For daily site work I would want something with more metal in the chassis.
Are the bundled auto-darkening goggles any good?
They are a real bargain – decent shade range, fast switching, and they convert to goggles for tight overhead work. They are not professional-grade, but they beat a basic fixed-shade hood for the price.
Plan to upgrade to a proper auto-darkening helmet once you have done 20 hours of welding and know what you like.
What is the lightest 3-in-1 welder currently shipping?
At 6.6 lb the XR MARKET is among the lightest 3-in-1 welders available. Lighter units exist but they tend to be single-process flux-core only.
If you need to carry the welder up ladders or in a small hatchback, the weight matters more than the headline amps.
7. BESTMIG 135A 3-in-1 MIG Welder with Helmet and Gloves – Best for Beginners
BESTMIG 135A MIG Welder – 3-in-1 Flux Core Welder, MIG/Lift TIG/Stick Welding Machine – Portable IGBT Inverter – 110V with Welding Helmets and Gloves (Red Black, MIG 135A Welder)
135A 3-in-1
Includes helmet and gloves
Digital auto control
10.7lb portable
Pros
- 135A output welds steel up to 1/8 inch
- MIG/Lift TIG/Stick in one unit
- Bundled helmet convertible to goggles and gloves
- Beginner-friendly all-in-one digital control
- Full-colour LED display
Cons
- Lift TIG torch sold separately
- Auto-feed less adjustable than manual wire-feed machines
The BESTMIG 135A is the kit I would give someone who wants to buy one box and start welding the same afternoon. Inside the package you get the welder, an auto-darkening helmet that converts to goggles, a set of leather gloves, ground clamp, electrode holder, and a starter reel of flux-core wire.
The digital auto control is the real headline feature. You press a single button, select the material thickness, and the welder auto-tunes voltage and wire feed. On 1.5 mm and 2 mm steel the auto mode produced a clean bead for our test welder, who had never used a MIG before that morning.
The 135A output covers mild steel up to about 1/8 inch (3.2 mm), which is the bulk of hobby work. The full-colour LED display is bright enough to read in direct sunlight – a small touch that makes first-time setup easier than squinting at a tiny LCD.
Where the BESTMIG gives up ground is in manual control. The auto-feed is convenient, but advanced users cannot tweak the inductance curve as much as on the Bestarc or ANDELI. For a first welder that is a feature, not a flaw.
Is the bundled helmet a keeper or a starter?
It is a starter. The shade is correct and the auto-darkening reaction time is fine, but the headgear is basic. Most welders upgrade within their first year.
For the first 30 hours of practice it is genuinely useful and saves a separate purchase.
What does the auto-feed do differently?
Auto-feed reads the wire-feed speed and adjusts the voltage to match, holding a stable arc without you touching the dials. Manual machines force you to set both knobs independently.
For beginners the auto mode removes the most common failure mode – mismatched voltage and wire feed that produces a hissing, spattery bead.
8. ANDELI 135A MIG Welder PULSE 4-in-1 – Best PULSE Flux Core Welder
ANDELI 110V/220V MIG Welder 135A ，PULSE Flux Core/Lift TIG/Stick 4-in-1
135A PULSE flux
110V/220V dual
Includes helmet and gloves
9lb body
Pros
- PULSE flux core for smoother arc and finer beads
- 110V/220V dual voltage flexibility
- Adjustable inductance for spatter control
- Comes with helmet
- gloves
- and consumables
- 9lb portable with carrying handle
Cons
- Lift TIG torch sold separately
- Bundled helmet is basic quality
The ANDELI 135A is the most interesting welder in this lineup because it brings PULSE flux-core technology down to a beginner price point. PULSE cycles the wire feed on and off rapidly, which cools the puddle between pulses and gives a much finer bead than standard flux-core MIG.
On 1 mm sheet metal the PULSE mode produced the cleanest bead of any welder I tested. The spatter was minimal and the heat input low enough to avoid warping the panel. For auto body or thin trailer work, this is a real advantage.
Adjustable inductance is the other stand-out feature. Turning the inductance up softens the arc for thin steel; turning it down hardens the arc for thicker steel. Most beginner machines do not give you that level of control.
Dual 110V/220V input with a 2T/4T trigger mode rounds out the spec sheet. The 9 lb body is easy to move, and the included helmet, gloves, and consumables let you start welding as soon as the parcel is open.
What does PULSE actually do for a beginner?
PULSE alternates between a high-heat and low-heat phase in the arc, which gives the puddle time to cool between pulses. The result is a smoother, more controlled bead with less spatter.
For thin materials where burn-through is a risk, PULSE is the closest thing a beginner gets to a professional synergic experience.
Why does inductance control matter on thin panels?
Inductance controls how soft or hard the arc feels. High inductance = soft, fluid puddle for thin steel. Low inductance = stiff, digging arc for thick steel. Without it you are stuck with one setting that is a compromise.
For a beginner who welds both thin and thick, the inductance knob is what stops you from blowing holes on day one.
UK Buying Guide for Beginner MIG Welders
What makes a MIG welder beginner-friendly?
A beginner-friendly MIG welder does three things well: it lights the arc easily, it holds the wire speed and voltage in step, and it does not require a gas cylinder to get a presentable weld. Inverter technology with synergic control checks all three boxes. Look for a unit that runs on a standard UK 240V plug, weighs under 15 kg, and includes a starter pack of flux-core wire.
Auto-darkening helmets, hot-start arc ignition, and thermal overload protection are the next layer of beginner friendliness. Skip welders that lack any of these – they make the first 20 hours harder than they need to be.
Can I plug a welder into a regular UK 13A socket?
Yes, most beginner MIG welders up to about 200A draw less than 13A on a 240V supply, which means they run on a standard UK 13A plug. A 16A supply on a commando socket will give you more headroom but is not required for sub-200A machines. The welders in this roundup all draw within the 13A limit on a domestic UK ring main.
If the welding trips your RCD, the cause is usually a long extension lead or a shared circuit with a kettle. Run the welder on a dedicated extension lead back to the consumer unit, ideally 2.5 mm² cable and under 10 metres.
Gas MIG vs gasless (flux core) – which should a beginner choose?
Gasless flux-core MIG is the right answer for most UK beginners because it removes the cost and hassle of a shielding gas cylinder. Flux-core wire contains its own shielding compound, so the weld works outdoors in a breeze. The trade-off is more spatter and a rougher finish than gas MIG.
Gas MIG with argon/CO2 mix gives a cleaner bead and finer control, but you need to rent or buy a cylinder, install a regulator, and refill it annually. For a beginner who wants to learn the basics first, start gasless and add a cylinder once you are confident. A 4-in-1 welder like the Bestarc 145A lets you do both.
Inverter vs transformer – does it matter for a beginner?
Inverter welders use modern IGBT electronics to step down mains voltage to the welding current. They are lighter, more efficient, and accept a wider input voltage range. Transformer welders use old-school copper and iron, weigh twice as much, and are less forgiving of dirty mains. For a beginner, an inverter is the clear choice.
Since January 2026 the EU Eco Design 2019/1784 regulation has phased out the most inefficient transformer welders, so most new stock is inverter-based. When buying in 2026, check the rating plate for an inverter sticker.
What amperage and duty cycle do I actually need?
For most UK hobby work on 1 mm to 3 mm mild steel, a 130A to 160A welder is plenty. Duty cycle tells you how long you can weld in a 10-minute window at full amps – a 60 percent duty cycle at 150A means 6 minutes welding, 4 minutes cooling. Beginners rarely run continuously for 6 minutes, so even a modest duty cycle is fine.
If you plan to weld 4 mm steel or thicker for long runs, prioritise a higher duty cycle over headline amps. The Bestarc 145A and HITBOX 200A both publish healthy duty cycles for hobby work.
What PPE do I need to MIG weld in the UK?
You need an auto-darkening welding helmet (shade 9 to 13 for MIG), a pair of leather welding gloves, a flame-retardant jacket or leather apron, and a respirator rated for welding fumes. Steel toe boots are sensible for shop work. Sparks and spatter can travel several metres, so a clear work area is part of the PPE.
Ventilation is not optional – weld outdoors or in a workshop with a fume extractor that meets UK HSE guidance. The XR MARKET and BESTMIG bundles include a basic helmet and gloves, but most welders upgrade within their first year.
How to Set Up a MIG Welder for the First Time
Your first weld in 10 steps
Connect the ground clamp to a clean piece of bare metal on your workpiece, not on painted or rusty surfaces. Fit a spool of flux-core wire (most welders ship with a starter spool), thread the wire through the drive roller and into the torch liner, then feed it through until it pokes 5 mm out of the contact tip.
Set the wire-feed speed and voltage using the chart on the inside of the wire compartment or the synergic auto-mode button. Hold the torch at a 10 to 15 degree push angle, about 10 mm from the workpiece, and pull the trigger. Strike a 50 mm bead on a piece of scrap, then inspect – if the bead is wide and flat, your voltage is too high; if it is tall and narrow with undercut, your wire feed is too slow.
Common beginner mistakes to avoid
The single most common first mistake is dragging the torch instead of pushing it. Pushing gives better penetration and a cleaner bead; dragging causes porosity and undercut. The second mistake is holding the torch too far from the workpiece – keep the contact tip 6 to 10 mm away for a stable arc.
Third, do not skip cleaning the metal. MIG welding does not forgive mill scale, paint, or rust the way stick welding does. A quick wire-brush pass and a wipe with acetone saves hours of remedial grinding.
Quick maintenance to extend welder life
Replace the contact tip every 10 to 15 hours of welding, or as soon as the arc starts wandering. Blow out the wire compartment with low-pressure compressed air monthly to clear dust. Check the drive roller for wear – if the wire starts slipping or deforming, swap the roller for a fresh one.
Store the welder in a dry place. Inverter electronics do not like condensation, and a damp garage is the most common cause of mid-life failure on budget machines.
Frequently Asked Questions
What is the best basic MIG welder for beginners in the UK?
The best basic MIG welder for a UK beginner is a 135A to 160A inverter with synergic control and a 240V plug. Our top pick is the YESWELDER 135A 3-in-1 because it has the largest UK user base and the simplest setup, but the Bestarc 145A 4-in-1 is the best value if you want gas MIG capability as well as gasless.
Are gasless MIG welders any good for a first welder?
Yes – gasless flux-core MIG welders are the right choice for most UK beginners because they skip the cost of a shielding gas cylinder and work in light wind. The trade-off is more spatter and a rougher bead than gas MIG, but you can always upgrade to gas later by switching wire and adding a regulator.
Can I plug a MIG welder into a regular UK 13A socket?
Yes, most beginner MIG welders under about 200A draw less than 13A on a 240V UK supply. Use a dedicated extension lead of at least 2.5 mm² cable and keep the run under 10 metres to avoid tripping the RCD. If you keep tripping, move the welder closer to the consumer unit.
What is the best budget MIG welder in the UK under typical hobby budgets?
For a typical UK hobbyist budget, the BESTMIG 135A Kit is our top budget pick because it includes a helmet and gloves alongside the welder. The AZZUNO 130A is the cheapest machine that still produces a respectable weld, and the Bestarc 145A 4-in-1 is the best value if you want gas MIG plus gasless in one unit.
Is flux core as strong as gas MIG for car body panels?
Flux-core welds are about as strong as gas MIG welds in pure tensile terms – both reach full parent-metal strength on mild steel. Gas MIG gives a cleaner, spatter-free finish which is easier to grind flat before painting, so it is preferred for visible body panels. For structural underbody work, flux-core is perfectly adequate.
Final Verdict – Which Best MIG Welder for Beginners UK Should You Buy?
If you want a single recommendation for the best MIG welder for beginners in the UK in 2026, the YESWELDER 135A 3-in-1 remains the safest pick. It has the largest user base of any welder in this roundup, the synergic control genuinely removes the hardest part of MIG setup, and the 11.4 lb body lives on a shelf without complaint.
Buyers who want gas MIG as well as gasless should spend a little more on the Bestarc 145A 4-in-1 – it is the highest-rated machine in this roundup and the only true 4-in-1 at the price. Buyers on the tightest budget get the BESTMIG 135A Kit, which bundles helmet and gloves so you can weld the day the parcel arrives.
Whichever you choose, run your first 20 beads on scrap, keep the contact tip 10 mm off the workpiece, and use a push angle rather than a drag. With those habits locked in, any of these eight welders will give you a serviceable MIG weld on a UK 240V supply.
