Detailed Product Description
1. CHARACTERS AND APPLICATION
The arc welder HM400/500, adopts IGBT element with PWM pulse modulation technology,
inverts low frequency 50Hz into a high frequency 25KHz, then reduces voltage
and rectifies current, outputs a high DC power soIt adopts advanced inverter technology
and IGBT element urce fit for welding. It has the following significant
characters:
It adopts PWM pulse modulation technology; its inverter frequency reaches 20KHz;
It is with rapid dynamic response, calm arc, perfect welding line and good welding
