ELECTRIC SHOCK can kill.
ž Do NOT operate the unit with
the cover removed.
ž Do NOT apply power to the
unit while holding or c a r r y -
ing the unit.
ž Do NOT touch any
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.
ž Wear welding helmet with No.
6 or 7 lens shade.
ž Wear eye, ear, and body pro-
tection.
Position the PowerCut 1500 at
least 3 meters (10 feet) from the
cutting area. Sparks and hot
slag from the cutting operation
can damage the unit.
3.3 CUTTING WITH THE POWERCUT-1500
Use the following procedures to cut with the PT-32EH torch (see ex-
ploded view of 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 5.5 bar (80 psig).
C. Hold the torch nozzle approximately 3.2 to 4.8 mm (1/8 to 3/16 inch)
above the work and tilted at about 15 - 30°. This reduces the chance
torch
of spatter entering the nozzle. If the PT-32EH's standoff guide is being
used, the distance between electrode and work piece will be approx.
4.8 mm (3/16 inch). 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 (see figure below). This angle is especially useful in helping to
create a "drop" cut. When not using the standoff guide, the nozzle
should be held approximately 6.4 mm (1/4 inch) from the work.
