4.2 Cutting with the Powercut-1300/1600 using the PT-38 torch
Use the following procedures to cut with the PT-38 torch.
A. Make sure that the wall disconnect switch is on and air is supplied to machine.
B. Turn on the front panel power switch.
C. Flip toggle switch upward to place unit in "GAS TEST" mode. Set Pressure Regulator to 80 psig (5.5 bar).
D. Place unit in Normal Trigger (CENTER position) or Trigger Lock (DOWN position).
E. Hold the torch nozzle approximately 1/8 - 1/4 inch (3.2 - 6.4 mm) above the work and tilted at about 5 -15°. This reduces
the chance of spatter entering the nozzle. If the PT-38's 90A stand-off guide is being used, the distance between nozzle
and work piece will be approximately 1/4" (6.4 mm).
F. Depress the torch switch. Air should flow from the torch nozzle.
G. Two seconds after depressing the torch switch, the pilot arc should start. The main arc should immediately follow,
allowing the cut to begin. (If using the TRIGGER LOCK feature, torch switch may be released after establishing the
cutting arc.) See note.
NOTE: Trigger Lock Mode.
Manual Operation using the PT-38 torch - When placed in TRIGGER LOCK position, this permits re-
leasing torch switch button after cutting arc has been initiated. To extinguish arc at end of cut, press
and release torch switch button again or pull torch away from work. When placed in NORMAL TRIGGER
position, torch switch must be held closed by the operator during the entire cutting operation and then
released at the end of cut.
