The best MIG/MAG welding machines, compared.
Top pick: Reboot RBM2100 MAX Best value: HZXVOGEN MIG145II – Same £99.99 shelf price in a 3.4 kg cabinet, with 0.8 mm flux-core wire and MMA rods listed. 4.4 from 543 reviews, shared with the 205 A sibling. Manuals and breaker trips are the recurring complaints. Updated October 2026.
Gas-shielded MAG uses a CO₂ or argon mix. Gasless listings use flux-core wire that makes its own shield. The eight amazon.co.uk rows here are single-phase inverters for a garage, a farm gate or DIY fabrication: flux-core in a draught, and bottled gas indoors when the listing actually has a gas path. Title figures of 135–250 A are peak welding current, not what a 13 A BS 1363 fuse will hold on a 230 V ring. This capture does not print a duty-cycle percentage, so treat a high dial as burst work. HSE treats all welding fume, including mild steel MIG, as needing exposure control. Quality is not the biggest amp number on the title. How to choose is set out in the [MIG/MAG welding machine buying guide](/hub/soldering-and-welding/mig-mag-welding-machine/sub/mig-mag-welding-machine-buying-guide).

Personal buying guide
Question 1 of 2
Where will you strike the arc?
Reboot’s RBM2100 MAX at about £142.12 shows 4.9 stars from only 21 UK reviews. The average looks high and the file is thin next to the HITBOX hundreds. Positive posts compare weld consistency with decades-old gas MIG kit and praise flux-core stability on gaps and exhaust work. Several buyers note the box can arrive without welding wire despite photos, so check the included-components line before you plan a weekend job. That line lists a gas hose, a manual, the welder, a MIG torch, a ground clamp and an electrode holder. It does not list a spool. Internal plastics get honest mentions at this price, and lift TIG remains a torch-extra mode. Aluminium is in the title. Confirm the liner, the roller and any spool gun before alloy work. At 12.7 kg it is the heaviest cabinet here.
Pros
Cons
Best for: You want a Reboot flux-core and gas box in the middle of this price band and you can accept 21 reviews.
Less suitable: You rank review depth above the star average, or you need wire in the box on day one.
Specifications
Common questions
Does the RBM2100 MAX run flux-core?
The process line names flux-core or gasless MIG and gas-shielded MIG/MAG, plus lift TIG. The components list a gas hose and a MIG torch. Welding wire is not in that list, and reviews say some boxes arrived without it.
Can it weld aluminium as titled?
Aluminium is in the title. The capture does not show a spool gun or a named liner in the box. Treat alloy welding as extra parts until the listing names the roller and the liner for the wire you buy.
What supply is listed for the RBM2100 MAX?
Power source is AC/DC and the title says 240 V. A 13 A fuse will not feed the top of a 210 A dial for long. No duty-cycle percentage is in this capture. Weight is 12.7 kg.
The FEIFANKE 145 A synergic welder at about £189.99 posts 4.9 stars from 13 UK reviews — the highest average here with one of the smallest samples. Short praise covers both gas MIG and gasless once the machine is set, and there is little volume to show recurring faults. The listing bundles flux-core and solid wire samples (0.5 kg of 1.0 mm flux-core and 0.5 kg of 0.8 mm solid), several nozzles and a 15AK gas torch. That is a full paper kit for a 145 A class machine priced above the HITBOX and the HZXVOGEN 145 A rows. You are trading review certainty for kit contents. No duty cycle appears in the capture. Aluminium is not in the title, so keep the job to mild steel unless you add the right wire path. A 205 A multiprocess row exists near this money.
Pros
Cons
Best for: You want bundled wire and nozzles and you accept a 13-review pool.
Less suitable: You want hundreds of UK texts before spending near £190 on 145 A.
Specifications
Common questions
Does the FEIFANKE include flux-core wire?
Yes. Included components list 0.5 kg of 1.0 mm flux-cored wire and 0.5 kg of 0.8 mm solid wire, plus 0.8 mm and 1.0 mm nozzles and knurled and V rollers. The process line covers gasless and gas MIG.
Does the FEIFANKE claim aluminium?
Aluminium is not in the title. The wire in the box is flux-core and solid steel sizes. Alloy work needs a liner and roller the listing does not name as included.
What voltage does the FEIFANKE listing state?
The comparison supply is 240 volts, and the technical power source is AC/DC. Wattage is listed as 4,000 watts. A 13 A plug is a poor match for the top of the dial. Weight is 8.7 kg. No duty cycle is printed.
Across 573 amazon.co.uk reviews at 4.4 stars, the HITBOX HBM200 at about £99.99 carries the deepest UK sample in this table and still undercuts several 205 A titles. Buyers praise compact flux-core work on gates and trailer repairs once they dial in the one-knob synergic control, and several compare the torch and earth clamp with older Clarke-era kit. The listing itself notes that effective welding current sits below the 200 A headline, so treat the dial as burst output on a 13 A garage ring. UK texts also mention a sticky wire feed when you stitch-weld with lots of stop-start, and doubt that the amp scale is linear. Lift TIG and aluminium come up in reviews, but plan a separate torch. Weight and the box contents are not in this capture. No duty-cycle percentage is printed.
Pros
Cons
Best for: Garage DIY and farm-gate flux-core, where review depth matters more than the headline amp number.
Less suitable: You need a printed continuous output on a 13 A socket, or clean aluminium without extra kit.
Specifications
Common questions
Does the HITBOX run gasless flux-core wire?
The listing names flux-core or gasless MIG and gas-shielded MIG/MAG, plus MMA and lift TIG. Confirm the wire diameter in the bullets before you load a spool. The torch for lift TIG is described as often extra.
Can the HITBOX weld aluminium out of the box?
Aluminium is not in the title. Reviews talk about aluminium, but a spool gun and the right liner are not established as included. Do not plan alloy work from the 200 A headline alone.
What supply does the HITBOX listing expect?
The captured supply line is 230 V, which matches UK mains. A 13 A fused BS 1363 plug may not hold the top of a 200 A dial. The listing says usable current sits below that title, and no duty cycle is printed.
At about £99.99 and 3.4 kg, the HZXVOGEN MIG145II shares a 4.4 star line with 543 UK ratings — the same count as the pricier 205 A sibling in this capture — so read themes for this ASIN rather than assuming identical feedback. Reviewers who get on with it describe easy flux-core starts on DIY steel and straightforward MMA setup with the supplied holder. Synergic auto feed is a recurring plus for a first spool of 0.8 mm wire. The other side of the file is blunt: manuals and setup videos frustrate many buyers, and breaker trips on garage circuits appear when the dial is high on a shared ring. Some one-star returns cite confusing instructions more than arc quality. The box lists flux-core wire and contact tips, not a welding helmet. Budget for eye and face protection to BS EN ISO 16321-2, or a legacy EN 175 or EN 169 lens, before the first bead.
Pros
Cons
Best for: You want the low shelf price for a synergic flux-core box that already has a long star line.
Less suitable: You rely on a paper manual, or the garage circuit trips when other loads are on.
Specifications
Common questions
Does the MIG145II run gasless flux-core?
Yes. The process line names flux-core or gasless MIG, gas-shielded MIG/MAG, MMA and lift TIG. The included components list 0.8 mm flux-cored wire and 0.8 mm and 1.0 mm contact tips.
Is aluminium included on the MIG145II?
Aluminium is not in the title. A spool gun and a soft-wire liner are often sold separately even on boxes that mention alloy. This row is a mild-steel flux-core machine unless the live listing adds those parts.
What supply does the MIG145II listing give?
Power source is listed as DC, and the title says 240 V. UK mains are 230 V with a BS 1363 plug. Reviews report breaker trips when the dial is high on a shared ring. No duty cycle is printed.
The HZXVOGEN HVM205P at about £169.99 advertises 205 A, gas and gasless MIG, MMA, lift TIG and aluminium in the title, with a graphene liner named in the components list. UK-facing review themes mirror the 145 A row: synergic flux-core works for car and home repairs when the settings click, but confusing documentation and breaker trips on domestic rings recur. Because the 543-review star line is shared with the cheaper MIG145II in this capture, treat the written comments as family patterns, not proof this exact model differs. Feedback also mentions soft front knobs and aluminium that worked only after liner and roller changes. Check what is actually in the box before you plan alloy work. At 7.5 kg it is still a one-person lift. You are paying mid-set money without a review file that is clearly separate from the £99.99 sibling.
Pros
Cons
Best for: You have outgrown 145 A flux-core and want gas MIG plus stick in one cabinet.
Less suitable: You mainly want evidence depth at the lowest spend. Compare the HITBOX row first.
Specifications
Common questions
Does the HVM205P run gasless and gas?
Yes. The process line names flux-core or gasless MIG, gas-shielded MIG/MAG, MMA and lift TIG. Components include 0.8 mm wire, an air hose, a MIG torch and a graphene liner.
Is the aluminium claim ready to weld?
Aluminium is in the title, and a graphene liner is listed. A spool gun is not established as included. Reviews describe alloy work only after liner and roller changes. Confirm the roller groove before you buy aluminium wire.
Why is the 543-review line not a second sample?
This capture gives the HVM205P and the MIG145II the same 4.4 from 543 reviews. Read the written themes as a family pattern. Power source is DC and the title says 240 V. Weight is 7.5 kg. No duty cycle is printed.
The HZXVOGEN 250 A listing at about £249.99 is the most expensive inverter here and sits at 4.2 stars from 235 UK reviews, a harsher written tone than the 4.4 clusters below it. Fans describe garage work on trailers and frames once flux-core or gas modes are tuned, and pulse is mentioned in marketing. Critical UK posts focus on short earth leads, awkward cable exit angles, manuals that reference buttons the panel lacks, and pulse settings that were not there in practice. Buyers drawn by an aluminium story then found the TIG torch is not in the process line for this ASIN. Aluminium is not in the captured title field. At this price you are paying for the headline current. If you need a published duty cycle, dealer brands with a PDF sit outside this amazon capture. Treat 250 A on the dial as peak burst on UK 230 V, not continuous production welding. Weight is 8.5 kg.
Pros
Cons
Best for: You want the top amp dial in this amazon.co.uk set and you will sort lead lengths yourself.
Less suitable: You expect pulse controls on the panel, or aluminium without an accessory spend.
Specifications
Common questions
Does the MIG250DP run flux-core?
Yes. The process line names flux-core or gasless MIG and gas-shielded MIG/MAG. Components include a MIG torch, a gas tube, an electrode holder, 0.8 mm wire and a graphene tube. Lift TIG is not on that process line.
Is aluminium in the MIG250DP title?
Not in the captured title field. Reviews describe buyers who expected an aluminium torch and did not find it bundled. Do not buy this row for alloy work unless the live listing names the liner, the roller and the torch.
Will 250 A run all day on a 13 A plug?
No. Title amps are peak welding current, not socket capacity. UK rings are 230 V with BS 1363 plugs, and a 13 A fuse will not feed the top of this dial for long. No duty cycle is printed. The star line is 4.2 from 235 reviews.
Reboot’s RBM205PRO at about £189.04 is the most feature-dense title in the set: 7-in-1, dual aluminium paths, synergic MIG, and both a Teflon-liner story and an optional spool-gun story in the bullets. This capture has no UK review block, so there is no star line and you have to lean on the listing and on the thinner Reboot sibling. At 11.6 kg it is a heavier cabinet than the compact HITBOX. The box list names the machine, a MIG torch, an earth clamp, an electrode holder, a shielding gas hose and a manual. It does not name a spool of wire. Confirm the BS 1363 fuse rating. Expect the lift TIG torch and a spool gun as extras. Do not assume aluminium works until the liner and the roller match the wire you buy. The price sits next to the FEIFANKE with none of that short review file.
Pros
Cons
Best for: You want the Reboot feature list and you will check every included part on the live listing.
Less suitable: You want an amazon.co.uk review count before paying upper mid-set money.
Specifications
Common questions
Does the RBM205PRO state flux-core?
The captured process field says MIG/MAG multiprocess, not a plain flux-core line. A gas hose is included. Confirm gasless wire in the live bullets before you skip a bottle. No review line is in this capture.
Can the RBM205PRO weld aluminium out of the box?
Aluminium is in the title, and the copy names dual aluminium paths plus a Teflon liner and an optional spool gun. Those extras are often sold separately. Match the roller and the liner to the wire before you rely on the claim.
What supply does the RBM205PRO listing expect?
Power source is AC/DC. A 13 A fused plug may not sustain the top of a 205 A dial. Weight is 11.6 kg. No duty cycle and no amazon.co.uk star line are in this capture. The shelf price is about £189.04.
The DEKO inverter at about £79.99 is the cheapest row. The captured process field lists MMA or stick and lift TIG, not flux-core and not gas MIG. That matters on this page: it belongs with an electrode welder unless the live listing clearly restores wire feed. There is no review block in the short capture, so there is no UK star line to set against the £99.99 MIG boxes. At 6.96 kg it is a plausible occasional stick machine for tacks. Buying it from this table because you want MIG/MAG wire will disappoint. Confirm the amazon.co.uk page before checkout if the job is wire-first. Even as stick, plan a helmet, fume control and a realistic 135 A burst limit on a 13 A plug. Synergic is mentioned in the marketing line.
Pros
Cons
Best for: You want stick first, and you will confirm the live listing is still MMA rather than wire.
Less suitable: You are on this page for flux-core or gas wire welding.
Specifications
Common questions
Does the DEKO run gasless flux-core wire?
Not on the captured process field. That field lists MMA or stick and lift TIG. The title still says MIG welder. Open the live amazon.co.uk bullets and confirm a wire feed before you treat it as MIG/MAG.
Can the DEKO weld aluminium out of the box?
Aluminium is not in the title. Lift TIG is named, and the torch is the usual extra. There is no spool-gun or liner line in this capture, and there is no review file.
What supply does the DEKO listing expect?
The captured supply is 230 V, in line with UK mains. A 13 A fuse is a limit on the top of a 135 A dial, and no duty cycle is printed. Weight is 6.96 kg. The shelf price is about £79.99, with no star line in the capture.
Eight amazon.co.uk listings were scored for this page. Weights sum to 100. A title amp figure, a synergic label and an aluminium line are seller claims, not a measured weld. There was no lab test. Display scores that are only the star rating times 20 are reduced when the review count is under about 30, or missing. The two HZXVOGEN rows that share one 543-review line are not treated as two independent samples. Prices are the 19–20 October 2026 shelf figures.
Amazon evidence
30%Star rating on amazon.co.uk, with a hard deduction when the count is under about 30, under 10, or when the capture has no out-of-five line. A missing star line scores as no evidence. A shared count on two HZXVOGEN ASINs does not double the sample.
Listing fit
30%A wire process first: flux-core, gas MIG/MAG, or both. Synergic control, a stated supply, and whether aluminium is only a title word. A stick-and-lift-TIG row with no wire mode scores low here. A 13 A plug limit is assumed when no duty cycle is printed.
Review outcome
25%UK review notes on wire feed, manuals, breaker trips, missing wire, short leads and aluminium that needed a liner or roller. Thin files stay low on this part even when the average is 4.9.
Value
15%Shelf price in GBP against a flux-core or gas path the listing actually describes. The lowest complete synergic box with a long star line scores highest here. A low price does not erase a missing review line or a missing wire mode.
The checks run in this order: wire process, gas or gasless, supply and duty, the spool path, then extras and price. The table is the eight listings. None of these machines was measured in a lab for this page. A title amp, a synergic label and an aluminium word stay seller claims. Welding fume controls still apply on the cheapest row.
A MIG/MAG welding machine feeds continuous wire through a torch while an arc melts the joint. Gas-shielded MAG uses a CO₂ or argon mix. Gasless listings use flux-core wire that makes its own shield. UK buyers in this amazon.co.uk set are garage, farm-gate and DIY fabricators who want one 230 V box that can run flux-core outdoors and, on some rows, bottled gas indoors. Quality is not the biggest amp number on the title.
Aluminium welding needs the liner, the U-groove roller and the wire the listing names. A spool gun is rarely in the box. The Reboot titles and the HVM205P mention aluminium. That is not proof the parts are included.
Wind blows the shielding gas off the puddle and defeats fume control. Flux-core is the outdoor process in this set. Gas MIG belongs indoors, with a regulator and a bottle stored upright.
Title amps are peak current. A BS 1363 13 A fuse will not feed the top of a 200 A or 250 A dial for long. This capture prints no duty-cycle percentage. Stop when the machine cuts out on temperature.
Start with the process the listing actually names. Flux-core and gas MIG are the point of this page. Stick and lift TIG are extras, and on the DEKO row they are the whole captured process field. Gasless wire tolerates a draught. Gas MIG needs still air and a bottle. UK mains are 230 V. Several titles say 240 V, which is the same nominal supply, not a second socket. A 13 A fuse is the limit on a domestic ring. The HITBOX listing already says usable current sits below its 200 A title.
Check the roller, the liner and the spool size before the amp number. The MIG145II lists 0.8 mm flux-core wire. The FEIFANKE lists flux-core and solid samples. The RBM2100 MAX components list does not include wire, and reviews say some boxes arrived without it. The HITBOX box list is missing from this capture. Aluminium needs a U-groove roller and often a soft liner. If those parts are not named, the alloy claim is marketing. Then read the review count, not only the average.
Three typical situations, each with a recommendation from this comparison.
You want synergic flux-core on 2–4 mm mild steel and a review file you can read. The HITBOX HBM200 is the top pick in this set: 4.4 from 573 reviews at about £99.99. The listing says usable current sits below the 200 A title, and reviews mention a sticky feed on stop-start stitches.
You want flux-core, a light cabinet and MMA practice rods at about £99.99. The HZXVOGEN MIG145II is the best value here, at 3.4 kg, with 4.4 from 543 reviews. That count is shared with the 205 A sibling. Reviews cite manuals and breaker trips on a shared ring.
You want the 250 A dial in this amazon.co.uk set and you will sort leads yourself. The HZXVOGEN MIG250DP is about £249.99, with 4.2 from 235 reviews. Reviews mention short earth leads and a manual that does not match the panel. Treat 250 A as burst output on 230 V.
The top pick is the HITBOX HBM200, at about £99.99, with 4.4 from 573 reviews, the longest UK sample in this set, and synergic flux-core plus a gas path on the listing. Reviews mention a sticky wire feed on stop-start work, and the listing caps usable current below the 200 A title. The best value is the HZXVOGEN MIG145II at the same £99.99, at 3.4 kg, with flux-core wire in the box and 4.4 from 543 reviews. That 543-count is shared with the dearer 205 A sibling, and reviewers criticise the manual and breaker trips. A 4.9 from 13 or 21 reviews does not lead this page. The DEKO row does not list a wire mode in the captured process field.
HZXVOGEN MIG145II
Same £99.99 shelf price in a 3.4 kg cabinet, with 0.8 mm flux-core wire and MMA rods listed. 4.4 from 543 reviews, shared with the 205 A sibling. Manuals and breaker trips are the recurring complaints.
