Pierce a workpiece
The hand torch can pierce interior features on metal. The type of pierce that you do relates to the
thickness of the workpiece and the pierce capacity of the plasma power supply. (Refer to
Recommended pierce capacity on page 35.)

Straight pierce – Use a straight pierce to cut a workpiece that is thinner than 8 mm
(5/16 inch). If a straight pierce does not pierce the workpiece, try a rolling pierce.

Rolling pierce – Use a rolling pierce to cut a workpiece that is 8 mm (5/16 inch) or thicker,
or if a straight pierce does not pierce the workpiece.
1. Attach the work clamp to the workpiece.
2. Straight pierce: Hold the torch perpendicular (90°) to the workpiece.
Rolling pierce: Hold the torch at an approximate 30° angle to the workpiece with the torch tip
touching the workpiece before firing 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 torch tip.
Point the torch away from yourself and others. Always put on correct protective equipment
including gloves and eye protection.
