Control, and aluminum · review
The only machine on this page that publishes a 100% duty cycle figure — 155 A, all day, with a number attached.
Where we come out The most honest specification sheet in this price band, on a German-market-only listing.
Two hundred amps, HF start, pulse, digital control with a job memory, a 4 m (13 ft) SR 26 torch in the box — and one figure that makes this machine stand out at €270: 100% duty cycle at 155 A.
Most listings publish a maximum current and nothing else. Duty cycle is what tells you how long the machine holds a current before its thermal protection intervenes, expressed as a percentage of a ten-minute period. « 100% at 155 A » means it does not stop at all at that current. Machines in this bracket typically manage 60% at their rated maximum and rather less on a hot day; a manufacturer that publishes a continuous figure is one that expects to be held to it.
HF start, so the tungsten never touches the work and stays sharp for longer. Pulse, which is what lets you put heat in without warping thin material. Hot start and anti-stick on the MMA side. A digital panel with job memory — the parameters that worked on 1.5 mm (0.06 in) stainless are recalled rather than found again.
The torch is worth noting: a 4 m (13 ft) SR 26 with a part-leather sheath and a ball-joint handle. Torches at this length are usually the first upgrade owners buy, and it is included here.
The reference resolves on the German store and, at the time of checking, on none of the other five. That is stated in the specification table rather than hidden: readers elsewhere are sent to a local search rather than to a page that does not exist.
Current, duty cycle, processes, control features, supplied torch and warranty come from the manufacturer’s published specification. Market availability was verified per market on the EAN.

It is worth knowing about. It means the machine can weld continuously at 155 A without thermal cut-out — no counting minutes, no waiting for the fan. For tacking and short beads it changes nothing. For a long run of stainless tube or a repair you want to finish in one heat, it is the difference between working and waiting.
Storing a set of parameters — current, pulse frequency, up-slope, post-flow — so you can return to a material and thickness without dialing it in again. It matters most if you weld several different jobs: the settings for 1 mm (0.04 in) stainless and 4 mm (0.16 in) steel have nothing in common, and rediscovering them each time is where an evening goes.
