Piercing
Hold the torch so that the nozzle is within 1/8 inch (3 mm) from the workpiece before firing the torch.
Fire the torch at an angle to the workpiece, then
slowly rotate it to an upright position.
When sparks are exiting from the bottom of the
workpiece, the arc has pierced through the material.
When the pierce is complete, 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.
