There has to be a very large voltage pulse whenever a welding arc is struck.A welder is a large inductive circuit with an 80 volt open circuit.The pulse will happen when the arc is broken for sure.A 6v ignition can generate a 200 volt pulse when the points open,ever been shocked when opening points by hand.You would have to watch the arc voltage on an oscilloscope to prove the actual voltage present when the arc is broken.If a 6 volt ignition can produce a pulse that is 33 times higher, could a welder at 80 volts.produce a 2680 volt pulse?This would eat solid state devises.Welder diodes have rc network to protect them from hi voltages.Weldors have been warned to keep their bodies out of the welding circuit.Not an engineer,just a fellow who started working in electtonics in 1950.
