8. Cut as usual. Simply release the trigger assembly
to stop cutting.
9. Follow normal recommended cutting practices as
provided in the power supply operator's manual.
NOTE
When the shield cup is properly installed, there
is a slight gap between the shield cup and the
torch handle. Gas vents through this gap as
part of normal operation. Do not attempt to
force the shield cup to close this gap. Forcing
the shield cup against the torch head or torch
handle can damage components.
D. Piercing With Hand Torch
1. The torch can be comfortably held in one hand
or steadied with two hands. Position the hand to
press the Trigger on the torch handle. With the
hand torch, the hand may be positioned close to
the torch head for maximum control or near the
back end for maximum heat protection. Choose the
technique that feels most comfortable and allows
good control and movement.
NOTE
The tip should never come in contact with the
workpiece except during drag cutting opera-
tions.
2. Angle the torch slightly to direct blowback particles
away from the torch tip (and operator) rather than
directly back into it until the pierce is complete.
3. In a portion of the unwanted metal start the pierce
off the cutting line and then continue the cut onto
the line. Hold the torch perpendicular to the work-
piece after the pierce is complete.
4. Hold the torch away from your body.
5. Slide the trigger release toward the back of the
torch handle while simultaneously squeezing the
trigger. The pilot arc will start.
