It can work on single-phase supplies and 230-volt, 16A or 10A supplies. It can also be used with a generator power supply, even with extra-long extension cables of more than 100m.

A large LED meter display, remote current control option and Lift TIG ignition are standard. Precise arc ignition, large voltage reserves and automatic arc dynamics control mean it’s suitable for welding with all electrode types.
