7. Bring the torch within transfer distance to the work.
The main arc will transfer to the work, and the pilot
arc will shut OFF.
NOTE!
The gas preflow and postflow are a charac-
teristic of the power supply and not a func-
tion of the torch.

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 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.

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.
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 per-
formance:
• Torch parts wear
• Air quality
• Line voltage fluctuations
• Torch standoff height
• Proper work cable connection
