The MIB-300A and MIB-600A AC inverter welding power supplies from Amada Weld Tech Inc. (Monrovia, CA) offer increased control, resulting in more exact heat input and better-quality welds compared to traditional AC weld controls.
The AC inverter uses inverter technology with pulse-width modulation (PWM) to produce and simulate an AC waveform. Unlike AC welders that use line frequency and depend on well-regulated facility power, the AC inverter can produce an AC frequency from 50 Hz to 500 Hz. This allows more precise energy delivery in less time, isn’t affected by line voltage fluctuation, and provides a balanced three-phase load.
The units feature secondary constant current control; up to 20 pulses per weld; and the ability to set upslope, downslope and weld-interrupt. Up and downslope improve energy input into the welded material. Weld-interrupt stops the flow of current if displacement breaches a set level, preventing overwelding.
The units 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, they may be used for a variety of welding applications. Common uses for AC inverters include sheet metal welding, wire compacting, and brazing.
