Kempomig-power sources are MIG/MAG and MMA –power sources designed for professional use.
Kempomig-power sources are inverter power sources based on IGBTs controlled by PWM principle.
The operating frequency is fixed on 18 kHz throughout the machine´s operating range.
Kempomig-power source together with Feed-unit form a compilation, in which the Feed-unit controls
all the operations. Feed-unit´s all functions are programmatically controlled.
