Multi-Process Welding Applications
The Weldrnan UNI series heavy duty, energy efficient inverter power sources are multi-process machine
capable of delivering either constant current (CC) or constant voltage (CV) DC welding power using proven
IGBT power transformation technology. When coupled with the WE4R wire feeder, the machines provide
excellent arc characteristics with both solid and flux. cored wire welding. These machines render excellent
performance for stick welding with various types of electrodes and also for scratch-start TIG application.
Heavy duty welding at high current is achieved due to careful design and layout of components and cooling
arrangement. The power source is highly energy efficient.

FEATU RES
