3 – Operation
Gouge a workpiece
1. Hold the torch so that the torch tip is slightly above the workpiece before firing the torch.
2. Hold the torch at a 30 – 45° angle to the workpiece, with a small gap between the torch tip and the workpiece. Press
the trigger to obtain a pilot arc. Transfer the arc to the workpiece.
3. Change the torch’s angle as needed to achieve the desired dimensions for the gouge. Refer to Varying the gouge
profile on page 37 and 125 A gouging profile chart on page 37.
4. Maintain the same angle to the workpiece as you feed into the gouge. Push the plasma arc in the direction of the
gouge you want to create. Keep a small distance between the torch tip and the molten metal to avoid reducing
consumable life or damaging the torch.
WARNING!
SPARKS AND HOT METAL CAN INJURE EYES AND BURN SKIN
When firing the torch at an angle, sparks and hot metal will spray out from the nozzle. Point the torch
away from yourself and others. Always wear proper protective equipment including gloves and eye
