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.
5. Slide the trigger release toward the back
of the torch handle while simultaneously
squeezing the trigger. The pilot arc will
start.

6. Bring the torch within transfer distance
to the work. The main arc will transfer to
the work, and the pilot arc will shut off.
NOTES
The gas preflow and postflow are a characteristic
of the power supply and not a function of the
torch.
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 performance:
• Torch parts wear
• Air quality
• Line voltage uctuations
• Torch standoff height
• Proper work cable connection

WARNINGS
Be sure the operator is equipped with proper
gloves, clothing, eye and ear protection and
that all safety precautions at the front of this
manual have been followed. Make sure no part
of the operator’s body comes in contact with the
workpiece when the torch is activated.
Disconnect primary power to the system
before disassembling the torch, leads, or
power supply.
CAUTION
Sparks from plasma gouging can cause damage
to coated, painted or other surfaces such as glass,
plastic, and metal.
Check torch parts. The torch parts must
correspond with the type of operation. Refer to
Section 4T.07, Torch Parts Selection.
Gouging Parameters
Gouging performance depends on parameters
such as torch travel speed, current level, lead angle
(the angle between the torch and workpiece), and
the distance between the torch tip and workpiece
(standoff).
CAUTION
Touching the torch tip or shield cup to the work surface
will cause excessive parts wear.
