Bosch 800 amp 1000 Hertz Inverter Power Supply mounted under the weld transformer
Power supply connects to Inverter Transformer and secondary is rectified to D.C. This control system compensates on each pulse after the first pulse is detected, which means that compensation is 16.6 times more than that of conventional A.C. (60 HZ). Most generally, welding controls are set by using the peak values set by the AWS. RMS current is a more accurate method of setting up welding current. By using RMS values, the actual current flowing through a weld can be determined, which is much more reliable than measuring only the point at which current is at its peak.

Quality Assurance with Secondary Constant Current Voltage
Variations in resistance during welding are detected and fed back to the control unit. The advantage of this type of control is that reliable welds can be achieved regardless of fluctuations in power source voltage or weld defects that occur due to plating, oxides, oil or other contaminants, but with the high frequency inverter, weld current remains the same due to the ability to detect and correct current fluctuations at very high speeds. If unable to reach weld current, machine will shut down.
