SECTION 4 OPERATION

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. (3.2mm-

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. 3/16in. (.47mm).

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. (6.4mm) from the

work.

ELECTRIC SHOCK can kill.

• Do NOT operate the unit with the

cover removed.

• Do NOT apply power to the unit while

holding or carrying the unit.

• Do NOT touch any torch parts

forward of the torch handle (nozzle,

heat shield, electrode, etc.) with

power switch on.

ARC RAYS can burn eyes and skin;

NOISE can damage hearing.

• Wear welding helmet with No. 6 or 7

lens shade.

• Wear eye, ear, and body protection.
