July 31, 2020 | By MRO Magazine


AMADA WELD TECH Inc., MIB-300A and MIB-600A AC inverter welding power supplies, offer exact heat input and quality welds.

It uses inverter technology with pulse width modulation (PWM) to produce and simulate an AC waveform. AC inverter can produce an AC frequency from 50 to 500 Hz, is not affected by line voltage fluctuation, and provides a balanced three phase load.

MIB-300A and MIB-600A feature secondary constant current control, up to 20 pulses per weld and ability to set upslope, downslope and weld interrupt.

MIB-300A and MIB-600A may be used with the same transformers and weld heads as standard AC welders. With max output currents of 20,000 and 40,000 A respectively, the units may be used for a variety of welding applications.
