Output Voltage With Transferred Arc
The voltage is approximately 140VDC at the output diode bridge when the torch arc is
transferred to the workpiece. Take this reading across the two bars spanning output diodes
D2 and D3 (wires 29 and 30).
If the torch is not working, the voltage will be approximately 300VDC for 5 seconds and then
drop to 0VDC.
