Two AC Inverter Welding Power Supplies
Inverter technology with pulse-width modulation (PWM) enables Amada Weld Tech’s MIB-300A and MIB-600A power sources to provide better control than standard AC welders.

The MIB-300A and MIB-600A AC inverter welding power supplies fromAmada Weld Tech Inc.（蒙罗维亚，加利福尼亚州）提供更高的控制，导致与传统的交流焊接控制相比，更精确的热量输入和更好的焊缝。
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.
该单元可以与标准交流焊机相同的变压器和焊头一起使用。最大输出电流分别为20,000和40,000A，它们可用于各种焊接应用。AC逆变器的常用用途包括金属板焊接，电线压实和钎焊。
