CUTMASTER A60
OPERATION 4T-6 Manual 0-4982
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.
8. 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, posi-
tion the legs of the standoff guide against
the workpiece.

Cutting Guide
Using Drag Shield Cup With Straight Edge
The crown shield cup functions best when cutting
3/16 inch (4.7 mm) solid metal with relatively
smooth surface.
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.
1. Install the drag cutting tip and set the out-
put current.
2. 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
holding technique that feels most comfort-
able and allows good control and move-
ment.
4. Keep the torch in contact with the work-
piece during the cutting cycle.
5. Hold the torch away from your body.
6. Slide the trigger release toward the back
of the torch handle while simultaneously
squeezing the trigger. The pilot arc will
start.

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.
