8. Cut as usual. Simply release the trigger assem-
bly 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 in-
stalled, 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.

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 par-
ticles 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 workpiece after the pierce is complete.
4. Hold the torch away from your body.

7. Clean spatter and scale from the shield cup and
the tip as soon as possible. Spraying the shield
cup in anti - spatter compound will minimize the
amount of scale which adheres to it.
Cutting speed depends on material, thickness, and the
operator's ability to accurately follow the desired cut line.
The following factors may have an impact on system
performance:
