4.3 cuttINg WIth thE pt-32Eh
Use the following procedures to cut with the PT-32EH torch
(Figure 4-4).
A.
Hold the torch nozzle approximately 3.2mm to 4.8mm (1/8" to 3/16") above the work and tilted at about 15 - 30°. This
reduces the chance of spatter entering the nozzle. If the PT-32EH's standoff tool (P/N 0558002393) is being used, the
difference between the electrode and workpiece is approximately 4.8mm (3/16").
B.
Depress the torch switch. Air should flow from the torch nozzle.
C.
Two seconds after depressing the torch switch, the pilot arc should start. The main arc should immediately follow, al-
lowing the cut to begin. (If using the trigger LOCK mode, torch switch may be released after establishing the cutting
arc.)
D. 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
6.4mm (1/4 ") from the work.
E.
When ending a cut, the torch switch should be released (press and release if using trigger LOCK mode) and lifted off
the workpiece just before the end of the cut. This is to prevent the high frequency from reigniting after cutting arc
extinguishes and causing damage to the nozzle (double arcing).
