Welding manner: Gas shielded arc welding, flux-cord wire welding. Applicable materials: Low-carbon steel, high strength and normal steel. Control systerm: Adopted arc waveform control technology, with electronic reactor adjustment function to get high deposition efficiency, little splash, high productivity effect, power-saving against manual welding. Advanced technology: 1)IGBT soft switching make it high reliable. 2)Adopting function of high voltage and slow wire feed, effective striking arc. 3)Having function to protect from overheating, over-current, over-voltage, short circuit. 4)Continuous welding current and voltage for different welding needs make the best welding effect.
