High production rate + high yield = industrial process success. Understanding both the process requirements and production environment allows companies to optimize their production rates resulting in lower cost per part and higher profit.
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 allowing more precise energy delivery in less time, is not affected by line voltage fluctuation, and provides a balanced three phase load. AC inverters combine the energy efficiency of inverter technology with the even heating of AC welders and is capable of producing a square wave output or a sinusoidal waveform which emulates a normal AC signal. The AC Inverter uses the incoming AC line voltage and full wave rectifies it to a regulated DC voltage, this DC voltage is then pulse width modulated and the output is switched from positive to negative which results in an AC waveform. This high voltage signal is then sent to the transformer where the high voltage low current is converted to low voltage and high current. The AC inverter is capable of a wide range of current from 0.05 kA to over 40 kA depending on the transformer used and can proved weld times from 2 ms to several seconds. Common uses for AC inverters include sheet metal welding, wire compacting, and brazing.
