Where we come out The reach and the electrode size are the argument, not the number on the front.
A hundred dollars buys 250 A, a large LED readout with a rotary control, hot start, and — the specification that actually changes a working day — eight-meter leads on both sides.
Leads are the forgotten specification
Almost every machine at this price ships with 2 to 3 m (7 to 10 ft) of cable, which puts the welder within a pace of the joint. That is fine on a bench and awkward everywhere else: on a gate post, under a trailer, along a fence line. Eight meters each side means the machine stays where the extension cable reaches and you carry only the holder.
Buying a longer set afterwards is not cheap. Having it in the box at €100 is the reason to look at this machine rather than the 200 A ones beside it.
What 250 A is for
Four-millimeter electrodes. That is the practical meaning of the number: a bigger rod deposits more metal per pass, so 6 to 8 mm (0.24 to 0.31 in) sections can be joined in one run instead of three. The limit you will meet first is your supply — a 230 V machine drawing 250 A needs a circuit that can feed it, and most domestic sockets cannot for long.
What is not stated
No duty cycle, no arc force, no anti-stick figure. Hot start is listed and is the one that matters most for striking. For the rest, treat 250 A as a peak and expect to work comfortably in the middle of the range.
Sources
Current, electrode size, lead lengths, display and hot start come from the manufacturer’s published specification. Market availability was verified per market on the EAN; the reference was not live on the American store at the time of checking.

What it handles, and what it will not
Strengths
8 m (26 ft) leads as standard — you reach the work instead of moving the machine
250 A takes 4 mm (0.16 in) electrodes, which is a real step up in what you can weld in one pass
Five markets under one reference
Compromises
No published duty cycle, and 250 A on a 230 V supply will demand a serious circuit
No arc force or anti-stick stated
Single process — stick only

The questions welders ask
Do 8 m (26 ft) leads make a real difference?
More than the amperage does. Standard leads are 2 to 3 m (7 to 10 ft), which means the machine has to sit within arm’s reach of the weld — awkward on a gate, impossible under a trailer. Eight meters each side lets you leave the welder on the ground by the extension cable and take the holder to the work. Buying longer leads afterwards costs a significant share of this machine’s price.
What does 250 A let me do that 200 A does not?
Run 4 mm (0.16 in) electrodes comfortably, which means fewer passes on thick section — a 6 to 8 mm (0.24 to 0.31 in) plate joined in one run rather than three. Whether your supply will deliver it is a separate question: at that current a 230 V machine draws heavily, and a domestic 16 A circuit is the real limit, not the welder.
