Manual 0-5119 4T-5 OPERATION
4T.06 Hand Torch Operation
Standoff Cutting With Hand Torch
NOTE
For best performance and parts life, always use
the correct parts for the type of operation.
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
holding technique that feels most comfort-
able and allows good control and move-
ment.
NOTE
The tip should never come in contact with
the workpiece except during drag cutting
operations.
2. Depending on the cutting operation, do one
of the following:
a. For edge starts, hold the torch perpen-
dicular to the workpiece with the front
of the tip on the edge of the workpiece
at the point where the cut is to start.
b. For standoff cutting, hold the torch 1/8
- 3/8 in (3-9 mm) from the workpiece
as shown below.
Standoff Distance
3. Hold the torch away from your body.
4. Slide the trigger release toward the back
of the torch handle while simultaneously
squeezing the trigger. The pilot arc will
start.
5. 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.
6. Cut as usual. Simply release the trigger
assembly to stop cutting.
7. Follow normal recommended cutting
practices as provided in the power supply
operator's manual.
