SECTION 3 OPERATION
3.3 CUTTING WITH THE POWERCUT-1250 / 1500
Use the following procedures to cut with the PT-32EH torch.
A. Make sure that the wall disconnect switch is on. Turn on the Front
Panel Power Switch.
B. Set Pressure Regulator to 80 psig.
C. Hold the torch nozzle approximately 1/8 to 3/16 inch above the work and
tilted at about 15 - 30°. This reduces the chance of spatter entering the
nozzle. If the PT-32EH's standoff guide (P/N 0558002393) is being
used, the distance between Electrode and Work Piece will be approx.
3/16-inch.
D. Depress the torch switch. Air should flow from the torch nozzle.
E. 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 mode, torch switch may be released after
establishing the cutting arc.)
F. After starting the cut, the torch should be maintained at a 5-15° forward
angle (Figure 3-2). This angle is especially useful in helping to create
a "drop" cut. When not using the standoff guide, the nozzle should be
held approximately 1/4 inch from the work.
