4.3 Electrode Wear
Figure 4-3. Electrode Wear Limit
REPLACE ELECTRODE BEFORE WEAR BECOMES DEEPER THAN .060"
INCH (1.5 MM)
CAUTION
WORN
NEW
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
unscrewing 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.
