PRODUCT 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 WM series
•
Efficiency, energy saving, portable, stable arc, high no-load voltage, and with good compensation of arc force, can
meet various welding requirements in field work.
