The best TIG welding machines, compared.
Top pick: H HZXVOGEN HVT250P Best value: No best value – £104.49 is the lowest shelf price, and UK reviews on that SSimder pair still describe a 50 A fuse in a 13 A plug. Updated October 2026.
A TIG welding machine strikes an arc from a tungsten electrode under argon, and you add filler by hand when the joint needs it. UK buyers use one for thin steel, stainless steel, and aluminium. The [TIG welding machine buying guide](/hub/soldering-and-welding/tig-welding-machine/sub/tig-welding-machine-buying-guide) puts metal, supply, arc start, kit, and duty in that order. DC lift TIG plus stick is the lighter inverter for steel and stainless steel, not aluminium. A TIG welding machine is judged by stated supply and duty cycle, process match, and uK safety complaints.

Question 1 of 2
Which metal are you welding?
The H HZXVOGEN HVT250P combines AC/DC TIG, pulse, square-wave control and stick welding in a 13.5 kg package with a stated 200 A output. Its AC capability makes it the more relevant SSimder alternative when aluminium is part of the job, while the named WP-17 torch, earth clamp, electrode holder and argon hose cover several core connections. The listing also claims a broad 0.5–5 mm aluminium range, but that remains a seller claim rather than evidence from a controlled test. A foot pedal is supported but costs extra, and the listing gives neither input current nor duty cycle. That missing electrical information matters more than the attractive £254.99 price because the intended UK supply cannot be checked from the specification shown. The 4.9 rating is based on only 13 reviews, and all five review texts in the review sample are labelled United States, so it is not strong UK buying evidence.
Pros
Cons
Best for: A hobby buyer who needs AC for occasional aluminium work and will verify the input requirement before connecting the machine.
Less suitable: Anyone who needs a documented 13 A supply requirement, an included foot pedal or substantial UK review evidence.
Specifications
Common questions
Does the H HZXVOGEN HVT250P weld aluminium?
The bullet says AC mode is for aluminium and magnesium, and it states 0.5 mm to 5 mm aluminium. That is a listing claim. The listing has no weld procedure.
Is a foot pedal in the box?
No. The bullet says remote operation via a foot pedal is supported, and that the pedal is sold separately.
Are the reviews United Kingdom reviews?
The listing line is 4.9 from 13. All five review texts in the review sample are labelled United States.
The HITBOX HBT250P puts AC/DC pulse TIG and a stated 200 A output into an 8.6 kg machine, making it easier to move than the H HZXVOGEN. HF start, a published 0.5–200 Hz pulse range and 2T/4T control give you more visible process detail than most rows in this comparison. It is also one of only two listings here that claims AC operation for aluminium. However, the specification table does not state input current or thermal duty cycle, and the printed 10–90% figure refers to AC balance rather than how long the machine can weld under load. UK reviews describing about 27 A draw, a bridged 13 A fuse and leaking gas-hose joints are serious reasons to inspect the delivered unit before any attempt to use it. The foot pedal is not included, while the included-components field is too vague to establish that the box is a complete working kit. Its 4.3 rating across 62 reviews is broader UK evidence than the H HZXVOGEN sample, but it does not cancel the electrical and gas-seal complaints.
Pros
Cons
Best for: An experienced hobby user who needs AC/DC controls and is prepared to reject the machine immediately if the plug, fuse or gas connection is unsafe.
Less suitable: A beginner seeking a verified plug-in 13 A machine or a complete ready-to-weld package.
Specifications
Common questions
Does the HITBOX HBT250P come with a foot pedal?
No. The bullet says the foot pedal is not included and names a separate switch, ASIN B0G7FD6DC9.
Can it run from a 13 A plug?
The specification table does not state input current. United Kingdom reviews describe a 13 A plug with the fuse bridged, and one review states a draw of 27 A. The seller bullet says fuses were changed from 2024. Do not use a unit whose fuse has been altered.
Does the box include a regulator and argon?
A cylinder and a regulator are not named. Reviews discuss a gas hose that did not seal. The included-components cell only prints 1.
This SSimder offers DC lift TIG and stick welding for £104.49, with a stated 10–140 A range and a manageable 6.82 kg weight. The named WP-17 torch, electrode holder, earth clamp and manual make the basic contents clearer than the HITBOX included-components cell. Its DC-only process is aimed at steel and stainless steel rather than ordinary aluminium, and lift start is less convenient than the HF start named on both AC/DC machines. The 3.8 rating from 167 reviews is not an independent result because it is shared with the older SSimder ASIN in this comparison. More importantly, UK reviews describe a 50 A fuse fitted in a 13 A plug and cite a manual input figure of 22.7 A. The listing table instead prints 3 kW without stating input current, so the electrical record is internally inconsistent. Treat the low purchase price as secondary to checking the plug and nameplate; an altered fuse is a stop-and-return fault, not a workaround.
Pros
Cons
Best for: Budget DC practice on steel or stainless steel only after a safe, correctly rated UK supply has been confirmed.
Less suitable: Aluminium work, buyers wanting HF start, or anyone unable to verify the plug and input requirement.
Specifications
Common questions
Will this SSimder weld aluminium?
This listing does not claim AC or aluminium. The listing question is unanswered. The other SSimder listing, B08QVQ9FKH, says aluminium is not applicable.
Does it include a carry case?
The listing question is unanswered. The included-components line names the welder, a TIG torch, an electrode holder, a ground clamp, and a manual.
Why do reviews mention the plug fuse?
United Kingdom reviews in this listing describe a 50 A fuse in a 13 A plug, and one cites a manual input of 22.7 A. That is a reason to stop and return the unit, not a setup step.
The older SSimder listing is a compact 6 kg DC TIG and stick machine whose own bullet explicitly excludes aluminium. It names a TIG torch, electrode holder, earth clamp and manual, and the stick information includes 7018, 6013 and 6010 rods. For steel-only hobby practice, that is a more relevant specification than paying for unused AC controls. Confidence is weakened by a basic output conflict: the title says 140 A while the technical table prints 200 A. Its 3.8 rating from 167 reviews is the same shared pool used by the newer SSimder ASIN, so the two rows are not separate bodies of evidence. Shared UK reviews also describe about 22.7 A input and a 50 A fuse in a 13 A plug, while the listing itself does not provide a dependable input-current field. At £119.99 it costs more than the other SSimder listing without resolving those safety or specification gaps.
Pros
Cons
Best for: Occasional DC TIG or stick work on steel where the buyer can independently confirm a safe supply and accepts the listing inconsistencies.
Less suitable: Aluminium jobs, buyers expecting a distinct review record, or anyone wanting a clearly documented 13 A machine.
Specifications
Common questions
Can the SSimder on B08QVQ9FKH weld aluminium?
No. The bullet says it is not applicable to aluminium. It names stainless steel and carbon steel.
Is the output 140 A or 200 A?
The title says 140 A. The technical table prints an amperage capacity of 200 A. Both figures are in the listing and they conflict.
Is the 3.8 from 167 a separate test from the other SSimder?
No. ASIN B0FVWWVWB1 prints the same 3.8 from 167. Treat it as one shared review pool.
We compared four TIG welding machine listings on amazon.co.uk, snapshot 16 October 2026. The displayed score converts that listing’s star line to a 0–100 figure, then to the 1–10 scale on this page. It is not a weld trial. Review count, review geography, a shared SSimder pool, missing input current, a missing thermal duty cycle, and repeated fuse complaints are written in the notes. They do not add points on top of the star line, and they block a top-pick or best-value award. Price does not set the score. The weights below describe what the notes record. They sum to 100.
amazon.co.uk star line
40%The number follows the UK listing stars. A high line is not a laboratory score, and it is not United Kingdom opinion when the review sample is labelled United States.
Review count, geography, and shared pools
20%A 13-review sample and a star line shared by two SSimder ASINs are recorded. The same 3.8 from 167 is one pool, not two tests.
Stated supply and duty cycle
20%Input current and a thermal duty cycle at a stated amperage are the supply checks. None of the four listings prints them. A percentage without the current does not count.
Process match
12%AC/DC against DC-only, HF against lift, and whether aluminium is claimed or excluded. Seller thickness lines are not treated as a measured weld.
UK safety complaints
8%Bridged or oversized fuses in a 13 A plug, and gas-hose leaks, stay in the record. They do not become a setup step, and they block an award.
Choose the metal before the star rating. Aluminium needs AC. Mild steel and stainless steel are DC. Then ask whether the listing states an input current that is legal on a BS 1363 13 A plug, and whether a duty cycle is printed at that current.
A TIG welding machine in this comparison is an inverter that strikes an arc from a tungsten electrode under argon. You add filler by hand when the joint needs it. Two types stayed in the table. DC lift TIG plus stick is the lighter inverter for steel and stainless steel, not aluminium. That is the SSimder pair. The bullets on B0FVWWVWB1 say 10–140 A, while the model string says TIG-200.
The SSimder bullet on B08QVQ9FKH says aluminium is not applicable. The other SSimder listing does not claim AC. Aluminium and magnesium need the AC advertised on the HITBOX and the HZXVOGEN.
UK reviews cite about 27 A and a bridged fuse on the HITBOX, and about 22.7 A with a 50 A fuse in a 13 A plug on the SSimder pair. A larger fuse is not a setup step. If the circuit has to change, call an electrician.
The HITBOX bullet figure of 10–90% is AC balance. None of the four listings prints a thermal duty cycle at a stated current. A shared 3.8 from 167 on the two SSimder ASINs is one review pool, not two tests.
Metal comes first. Aluminium and magnesium need AC. Mild steel and stainless steel are DC. The HITBOX and HZXVOGEN bullets advertise AC. The SSimder on B08QVQ9FKH says it is not for aluminium. The newer SSimder file does not claim AC either. Seller lines about thickness are not a measured weld, so this page does not repeat them as a result. Arc start comes next. Lift start avoids a high-frequency spark. The newer SSimder listing names lift TIG.
UK plugs to BS 1363 are 13 A. If the manual states an input above 13 A, the machine needs a proper circuit, not a bigger fuse in a 13 A plug. R-Tech’s published 160 A sets are specified as 240 V 13 A at 35% duty, at £499 on that maker’s site. That machine is not one of these four ASINs. Listings that omit input current do not get the benefit of the doubt. UK reviews on the HITBOX describe about 27 A and a bridged 13 A fuse.
Three typical situations, each with a recommendation from this comparison.
You want DC TIG for brackets, exhausts, or stainless, and a supply you can trust. SSimder B08QVQ9FKH says aluminium is not applicable, at £119.99, and names a torch, holder, clamp, and manual. The title says 140 A and the table also prints 200 A. Shared UK reviews describe a 50 A fuse in a 13 A plug. Confirm the supply before you treat this as a usable DC machine.
An alloy wheel or a boat fitting needs AC, plus a budget for a pedal and for the plug question. The H HZXVOGEN HVT250P advertises AC/DC at £254.99, with the pedal sold separately. Input current and thermal duty cycle are not stated, and the 4.9 from 13 reviews in the sample is labelled United States. Verify the input before you connect it.
You want a published duty cycle and a stated input current. None of these four listings gives either. The HITBOX HBT250P has the broader UK review sample, 4.3 from 62, at £339.99, and it still lacks those two figures. UK reviews also describe a bridged 13 A fuse. This row does not meet a workshop specification.
The top pick is HITBOX HBT250P, with the highest score in this comparison (8.3 out of 10, from 62 amazon.co.uk reviews). A lower shelf price does not become best value while that fuse record stands.
No best value
£104.49 is the lowest shelf price, and UK reviews on that SSimder pair still describe a 50 A fuse in a 13 A plug.
