Pierce a workpiece
1. With the work clamp attached to the
workpiece, hold the torch at an approximate
30° angle to the workpiece with the
torch tip within 1/16 inch (1.5 mm) of the
workpiece before firing the torch.
2. Fire the torch while still at an angle to the
workpiece. Slowly rotate the torch to a
perpendicular (90°) position.
3. Hold the torch in place while continuing to
press the trigger. When sparks exit below
the workpiece, the arc has pierced the
material.
4. When the pierce is complete, drag the
nozzle lightly along the workpiece to
proceed with the cut.
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.
