4.2 cuttINg WIth thE pt-32Eh
Use the following procedures to cut with the PT-32EH torch (Figure 4-4).
1.
Make sure that the wall disconnect switch is on. Turn on the Power Switch to the cutting power source console.
2.
Set Pressure Regulator to 75 - 80 psig (5.2 - 5.5 bar).
3.
Hold the torch nozzle approximately 1/8 in. to 3/16 in. (3.2 mm-4.7mm) 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 in. (.47 mm).
4.
Depress the torch switch. Air should flow from the torch nozzle.
5.
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.)
6.
After starting the cut, the torch should be maintained at a 5-15° forward angle (Figure 4-2). 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 in. (6.4 mm) from the work.
