Workshop
Steel moves as it cools, and a weld pulls with far more force than any magnet can resist. A welding bench exists to hold the work square through that shrinkage, and every component on it is chosen with that single fact in mind.
Steel moves as it cools, and a weld pulls with far more force than any magnet can resist. A welding bench exists to hold the work square through that shrinkage, and every component on it is chosen with that single fact in mind.
The most demanding case: four corners to hold while the metal shrinks. The table decides the outcome more than the machine does.
Nothing is flat, nothing is square. What counts is the packing — shims, jacks, adjustable supports — not the flatness of the top.
Tacks fix the geometry. A table that lets you tack without fighting the part saves everything downstream.
When the part will not come to the table, the table becomes a mobile earth and a means of packing. That is a different trade.
| What you need | The right tool | What it will not do |
|---|---|---|
| Hold a corner while tacking | A bolted-down clamping square | A magnet will not resist shrinkage |
| Pull two edges together | A clamp or locking pliers | A magnet positions, it does not clamp |
| Position quickly before clamping | A welding magnet | It replaces no clamp at all |
| Carry the return current | A conductive table with a fixed earth | An earth on paint conducts nothing |
A welding table degrades by accumulation: spatter, tack marks, a top that has bowed. It never breaks down; it gradually becomes less accurate — and you find out on the parts.
A properly set-up welding station removes part of the risk before the arc is even struck.
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
200 A · 230 V · rutile, basic, stainless, cast iron to Ø 4 mm (0.16 in) · €263
The only machine in this batch live on all six markets, and the only one that names the electrode types it is built for.
Best for: Someone who welds cast iron or runs basic electrodes and wants the machine to cope
≈ $405
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
Because a cooling weld shrinks with more force than a 13 or 22 kg (48.5 lb) magnet can hold, and because magnets lose grip on hot steel. Their job is positioning: set the angle, tack both ends, remove the magnet, clamp mechanically, then weld. Skipping the middle steps is the commonest reason a frame is not square.
As close to the weld as practical, on clean bare metal. A long path through a table, a hinge or a bearing sends the current somewhere unintended — through bearings it causes pitting, and through a poor connection it makes the arc unstable in a way no machine setting will fix.
Thick enough not to bow under the heat of everyday work, reasonable enough to stay movable if space demands it. The compromise depends on what you weld; a thin top is paid for in distortion.
A holed table changes how you clamp: squares and jacks go wherever you want, and squareness becomes repeatable. A solid top stays better for dirty work and for dressing with a grinder.
Clamp firmly, tack at spread-out points before running continuous beads, and alternate sides to balance the shrinkage. Welding sequence matters as much as clamping.
Best avoided: the heat vaporizes the zinc and produces fume that no makeshift ventilation handles properly. A bare steel top, even a rusty one, is preferable.
General light strong enough to prepare and inspect, and a raking light to reveal surface defects. During the bead only contrast under the helmet counts: a dark background helps more than harsh light.
Only if it takes the loads of bending or straightening work. For welding alone, enough mass and adjustable feet beat an anchorage that stops you moving it.
For work that: A first serious MIG that will still be adequate after two years of use
Where it is best: Synergic control: you set the material and thickness, the machine sets the wire speed
Where it is worst: The duty cycle is not stated with its temperature in the listing, so 200 A is a ceiling, not a working figure
For work that: Someone who welds cast iron or runs basic electrodes and wants the machine to cope
Where it is best: Names the electrode families it handles — including basic and cast iron, which cheaper machines avoid mentioning
Where it is worst: €263, against €90 to €140 for the machines above it
For work that: Aluminum work, and anyone who wants the weld to look like the ones in the photographs
Where it is best: Pulse and double pulse, with aluminum synergic programs — the reason to buy it
Where it is worst: €600 buys 200 A here and 200 A elsewhere for half that — you are paying for pulse
Tips, nozzles, wire and gas from the same aisle, at the price we read. Confirm they suit the machine you choose before ordering: it turns on the torch and the part number, which the product page gives.
Welder against welder, where the comparison is already written up.
The welders here are taken from the catalog of this site. Specifications come from the maker and from the Amazon product page; prices are what Keepa reported for the date shown, and both move. The order rests on declared specifications, on stated strengths against stated limits, and on price. No machine here has struck an arc in our hands, and nothing on this page pretends it has.

Prices quoted in these summaries are dated readings. The live price is shown next to each product.
Welders and plasma cutters swing by a hundred dollars or more across the year, and the biggest "discounts" often land at prices the same model sold for six weeks earlier. UniverTrack tracks the real price history across retailers, spots fake reductions, and alerts you when it is genuinely the moment to buy.
