Mesurement Method

4-4. Note on the Use of Tip Voltage Detection Cable

Since induced electromotive force by welding current generates induction by the tip voltage detection

cable when measuring the tip voltage, as shown in the following figure, please make connection of the

tip voltage detection cable. When especially a lead is made to gather and is attached, induced electromotive

force becomes small and the tip voltage can measure correctly.
