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 1.5 mm (1/16 inch) 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.
