The Latest MOSFET Technology

The MOSFET transistor helps to provide the highest standard of performance combined with a compact and lightweight design. The result is 85% efficiency! The welding current is very stable and thus ensures a perfect weld every time.

TIG AC/DC Mode Switch

TIG welding is divided into AC (alternating current) and DC (direct current) welding. This allows for additional welding functionality such as welding aluminium.

Featuring ARC Force and Hot Start

With ARC Force, the current increases automatically when the arc is shorter. Hot Start automatically boosts the tension at the ignition of the arc, this function facilitates the electrical arc ignition. After ignition, the unit automatically returns to the pre-set voltage.
