The first machine most people buy
MIG is the process most people learn first, because the arc starts when you pull the trigger and keeps going. What separates machines is not the headline amperage but the wire feed and the honesty of the duty cycle. We compare feed rollers, low-end control on thin sheet, and whether a machine that claims gasless capability actually reverses its polarity.
160 A · 230 V · 8 kg (17.6 lb) · €176
An 8 kg (17.6 lb) three-process inverter with a seven-year manufacturer’s warranty and a German importer with a published address.
Best for: A first MIG where the budget is firm and the machine must still be repairable in five years
Gasless · 7.5 kg (16.5 lb) · D100 spools · €140
Seven and a half kilos, a set of tips and a reel of wire in the box — the machine you take to the work rather than the other way round.
Best for: Repairs away from the bench — gates, trailers, a bracket on a machine that cannot be moved
135 A · gasless · 60% duty cycle stated · €110
The cheapest machine on this page, and — unusually for the price — one that publishes a duty cycle figure at all.
Best for: A first machine for someone finding out whether they enjoy welding at all
200 A · gas and gasless · 3-in-1 · €160
A 200 A synergic machine at €160, sold under a brand with no service address — cheap for a reason we state plainly.
Best for: A one-off job where the machine only has to survive the project
160 A · gasless only · 3-in-1 · €200
A gasless-only machine, on purpose: no bottle, no regulator, no shielding to be blown away — for people who weld outdoors.
Best for: Gates, trailers, fence posts and anything welded where you cannot close a door
200 A · gasless · sold as a set · €200
A gasless 200 A set from a German seller — verified in Germany, and nowhere else, because the listing publishes no EAN.
Best for: Outdoor repair work in Germany, where the machine can be bought and returned locally
160 A · 230 V single phase · Euro torch connector · €505
A French-built trolley machine with a Euro connector and a 40 W feed motor — bought for the feed quality rather than for its headline current.
Best for: Someone who intends to keep the machine ten years and wants standard consumables
200 A · pulse and double pulse · aluminum synergics · €600
The only machine here with genuine pulse and a spool gun interface — which is what makes aluminum a normal job rather than a fight.
Best for: Aluminum work, and anyone who wants the weld to look like the ones in the photographs
20–160 A · 4-in-1 · 6.8 kg (15 lb) · €220
Four processes in a 6.8 kg (15 lb) case, and the only machine here whose lower limit — 20 A — is published as well as its ceiling.
Best for: A small workshop that wants one box for occasional stick, TIG and MIG work
200 A · synergic · gas and gasless · €330
The synergic 200 A inverter that most German workshops end up with, and the cheapest machine here with a genuinely adjustable inductance.
Best for: A first serious MIG that will still be adequate after two years of use
Italian-built trolley MIG · ~€1,550 across the EU
The one professional machine on this page — and the one whose price is the same in four countries, which tells you it is not a marketplace listing.
Best for: A workshop that welds most days and cannot afford the machine to be the reason work stops
Maximum current decides the thickness you can penetrate in one pass. Undersized, the machine lays metal on the surface without actually welding.
On bodywork the issue is not power but fineness of adjustment at the low end. Too much current goes through the sheet instead of joining it.
It is the most forgiving: it is learnt in a few hours. TIG takes weeks for a comparable result.
The proportion of time the machine can weld at a given current before it has to cool. A machine with high current but a poor duty cycle cuts out constantly.
Gas gives a markedly cleaner bead and will not hold in wind. Outdoors, gasless flux-cored is the only workable option.
An argon-CO2 mix for carbon steel, pure argon for aluminum. The exact mix changes penetration and the look of the bead.
Wire speed and voltage badly matched, or a poorly placed earth. The sound should be steady, like continuous frying.
On clean metal, as close as possible to the weld. An earth sitting on paint or rust is the number one cause of unstable arcs.
Yes, with pure argon, a suitable feeder and a PTFE-type liner. Aluminum wire is soft and birdnests in a steel liner.
A helmet with the right shade, gloves, covering cotton clothing and ventilation. The arc burns the eyes within seconds, even seen from the side.
MIG is the fastest process to learn, and the duty cycle says more than the advertised current. Put the earth on bare metal near the weld — it is the first cause of unstable arcs — and never approach an arc without a suitable helmet.
There is no table here, and the reason is in the listings. The figure published most often across these 11 products is processes, given by 8 of them — short of the four in five a column needs to compare rather than to display gaps. Each product page says what its own maker published.
Specifications: manufacturer sheets for welding and metalworking machines and the matching Amazon product pages. Prices and availability: Keepa.
