CUMASTER A80, A120
Manual 0-5119 4T-7 OPERATION
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 characteristic
of the power supply and not a function 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 op-
erator) 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 perpen-
dicular 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.
