1.2 Product introduction
Master S model welding machines are designed for industrial use and for welding all kinds of
covered electrodes. Master S is also suitable for carbon arc gouging.
In addition to the basic functions Master S 400 and 500 models include advanced functions
like HotStart, ArcForce, TIG mode and remote control, which are all set through the panel.
Both models come equipped with a voltage reduction device (VRD) that is designed to
