产品描述
IGBT Inverter Welding Machine
Feature
● Use powerful IGBT switches and advanced inverter control technology.
● Excellent arc characteristics and good welding performance.
● With anti-stick,hot start,arc force,strong compensation capability.
● With Auto protection functions of overcurrent and overheat.
● Single phase,portable,fan-cooled,MMA inverter welder,in this welding process,an electric arc is created between a coated consumable electrode and the work piece to be welded,causing the parent material to be fued together and the electrode to be melt.
