2. GENERAL DESCRIPTION
Advanced IGBT inverter technology
● High inverter frequency greatly reduces the volume and weight of the
welder.
● Great reduction in magnetic and resistance loss obviously enhances the
welding efficiency and energy saving effect.
● Switching frequency is beyond audio range, which almost eliminates noise
pollution.
Leading control mode
● Advanced control technology meets various welding applications and
greatly improves the welding performance.
● It can be widely used in acid and basic electrode welding.
● Easy arc starting, less spatter, stable current and good shaping.
Features of MMA series
● Efficiency, energy saving, portable, stable arc, high no-load voltage, and
with good compensation of arc force, are able to meet various welding
requirements in field work.
