Electrode Wear

If the electrode has a pit which is more than .06" (1.5mm) deep at its center, it must be replaced. This is done by unscrew-
ing the electrode in a counter-clockwise direction from the piston. If the electrode is used beyond this recommended
wear limit, damage to the torch and power source may occur. Nozzle life is also greatly reduced when using the electrode
below the recommended limit.
