OPERATION 4-6 Manual 0-5180
D. Follow normal recommended cutting practices
as provided in the power supply operating
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.
E. For a consistent standoff height from the
workpiece, install the standoff guide by sliding
it onto the torch shield cup. Install the guide
with the legs at the sides of the shield cup
body to maintain good visibility of the cutting
arc. During operation, position the legs of the
standoff guide against the workpiece.

• Drag Cutting With a Hand Torch
Drag cutting works best on metal 1/4"(6 mm) thick
or less.
NOTE
For best parts performance and life, always
use the correct parts for the type of opera-
tion.
A. Install the drag cutting tip and set the output
current.
B. 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 protec-
tion. Choose the holding technique that feels
most comfortable and allows good control and
movement.
C. Keep the torch in contact with the workpiece
during the cutting cycle.
D. Hold the torch away from your body.
E. Slide the trigger release toward the back of the
torch handle while simultaneously squeezing
the trigger. The arc will start.
