IGBT inverter submerged arc welding machine: ² Adopt Siemens IGBT module. ² Can continual adjust generating arc current and pushing current. ² Duty cycle up to 100%. ² Welding power has compensation function power web voltage has little influence during welding. ² Digital display makes current, voltage and welding speed setting precisely. ² Two methods of arc generating: scrape and whip. ² Equal feeding system make base metal distortion small, welding fast and effective, can weld more than 3mm carbon steel and stainless steel with submerge welding method. ² Increase equipment usage rate with manual arc welding and carbon arc gas gouging. All the CHD brand machines are one year guaranteed.
