These fan-cooled, single PCB design IGBT digital inverter power sources are built for MMA welding.
The welder automatically delivers optimal start and stop parameters according to your preset welding current.
Its booster circuit supplies extra voltage to achieve reliable arc ignition and excellent performance for cellulosic electrodes.
With wide current range and strong welding capability, this DC arc welder supports general, stainless steel and cellulosic welding rods.
The Hot Start function greatly improves arc striking performance even when using hard-to-ignite electrodes.
ARC FORCE allows users to adjust and obtain the ideal dynamic arc characteristics during welding.
The ANTI STICK feature cuts down current output so you can separate the electrode easily when it sticks to the workpiece.
