Technical explanation

Standard • IEC 60974-1 — an international standard for arc welding machines that defines safety and operating modes.

Supply voltage (U1) • 220V
Operation from a single-phase electrical network.

Open circuit voltage (U0) • 65V
Ensures easy arc ignition and stable start.

Output current range • 20A – 200A
Operating current adjustment range for materials of different thicknesses.

Output voltage (U2) • 28V
Standard operating voltage at maximum load mode.

Duty cycle (X)

60% — 200A
Means that in a 10-minute cycle:
the machine operates for 6 minutes at full load (200A)
and requires 4 minutes for cooling

100% — 155A
The machine can operate continuously at 155A without overheating.

Input current

Maximum consumed current (Imax) • 39A
Average effective consumption (Ieff) • 30A

Practical recommendation

Minimum recommended:

Circuit breaker • 25 – 32A
Cable • 4 – 6 mm²

Protection and construction data

Protection class • IP21S

IP21 means:

Protected against solid particles larger than 12 mm
Protected against vertically falling water drops

Intended for indoor work
Not recommended for use in rain or open environments without protection
