MMA-250 SV

IGBT Inverter DC MMA welding machines are used primarily to weld carbon steel, low and high alloy steel, stainless steel, cast iron and ductile iron.
The MMA welding process (Shielded Metal Arc welding / Manual Metal Arc welding) is activated by a stick consumable flux-encased electrode. The IGBT combines the simple gate-drive characteristics of the MOSFETs with the high-current and low-saturation-voltage capability of bipolar transistors.
