Method of detecting a welding voltage
First Claim
1. Method of detecting a welding process voltage detected between a welding torch and a workpiece, comprising the step of performing a calculation of the welding process voltage in real time, taking account of the interference variables including a calculated inductance and a resistance of a welding system, the calculation for determining inductance being performed at specific time intervals during a welding process without the welding process being affected.
