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.
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
operations.
2. Angle the torch slightly to direct blowback
particles away from the torch tip (and op -
erator) 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 per-
pendicular to the workpiece 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.
