INSTALLATION AND OPERATION

3.1 INSTALLATION
To mount the PT-19XL torch, refer to F-12-528 (PCM-
8), F-14-493 (PCC-11), or F-15-116 (ESP-1000 Sys-
tem).
To use 4-1/2 ft. to 25 ft. torches with the PCC-11, holes
must be drilled in the PCC-11 sheetmetal opposite the
7/16-20 L.H. and 7/16-20 R.H. fittings on the brass
power block. These holes should be fitted with appro-
priate bushings.
Recommended hole size: 1.094" Dia.
Recommended snap bushing: P/N 639533
The "B" L.H. fitting should be plugged with:
"B" size plug (PCC-8 P/N 996857) and nut
"B" L.H. (P/N 10N40).
The "C" L.H. fitting should be plugged with:
"C" size plug (P/N 996856) and nut "C" L.H.
(P/N 10N18).
The existing 1.073" and 1.500" diameter holes should
be covered or plugged.
3.2 OPERATION
ELECTRIC SHOCK CAN KILL. Precautionary mea-
sures should be taken to provide maximum protec-
tion against electric shock. Therefore, before mak-
ing any adjustments or performing any mainte-
nance on the torch, make sure the power to the
torch is shut off.
Never use oil or grease on this torch. Handle parts
only with clean hands on a clean surface. Oil and
grease are easily ignited and burn violently in the
presence of oxygen under pressure. Use silicone
lubricant only where directed.
Wear the usual protective gloves, clothing, and
helmet. Helmet with filter lens shade No. 6 or 7
should provide adequate protection for your eyes.

WARNING
D. If cutting arc is lost during a cut, the pilot arc will
immediately reignite as long as the switch is
depressed. You then have about 6 seconds to
move the torch close enough to work to rees-
tablish the cutting arc.
E. The cutting arc will extinguish at the end of the
cut; however, the start switch should be re-
leased to keep the pilot arc from reigniting.
Never touch any torch front end parts (Nozzle,
Retaining Cup, Etc.) unless the power switch is in
the off position, and primary power is shut off at the
disconnect.
A. Position the torch over the edge of the
workpiece with the tip of the nozzle set at about
3/8" above workpiece (standoff).
If piercing thick plate, increase standoff to 1/2" for up to
1/2" thick plate, 3/4" for thicker plate. Then return to
3/8" standoff after completing the pierce and you are
ready to cut.
B. Lower your protective helmet and activate
start switch. Pilot arc and high frequency will
energize and gas will start flowing. The pilot
arc should then transfer to the cutting arc.
NOTE
If cutting arc does not start within 6 seconds, the pilot
arc will shut off. Deactivate start switch. Check to be
sure gas pressures are adequate, work cable is firmly
connected to workpiece, cooling water is on, standoff
is about 3/8", etc. Then start from step one again.
C. Maintain the standoff of 3/8" throughout the cut
and move the torch at a rate that produces the
desired cut quality. The cutting should pro-
duce a straight fine spray of molten metal
emitting from beneath the workpiece as illus-
trated in Figure 4-1. See Table 2-1 for recom-
mended cutting speed range.

F. When cutting operation is completed, wait a
few minutes before placing the POWER switch
to the OFF position so that the cooling fan has
time to remove the heat from the unit. Then
shut off the primary power at the main discon-
nect switch.

D. Insert the nozzle into the torch.
E. Screw retaining cup onto the torch slowly to

against the gas swirl baffle (P/N 948142). Do
NOT overtighten.
F. Screw heat shield onto nozzle. Do NOT over-
tighten.
4.3 REPLACING ELECTRODE AND GAS
SWIRL BAFFLE
A. Remove heat shield, retaining cup, and nozzle
as described above.
B. Remove electrode by using the 7/16-inch nut
driver (P/N 996568 - supplied with the torch).
If electrode holder did not come out with tip,
then remove it by using removal tool (P/N
999630) supplied with the torch. The lugs will
engage with the slots on the tip holder. Make
sure you hold the nut driver or removal tool
straight, whether removing or reassembling
the electrode, to avoid damaging the gas baffle.
The gas swirl baffle should come out with the
electrode holder. If it does not, remove by
using one finger.
C. Replace electrode if the hafnium insert is pit-
ted more than 0.090 inch.

4.1 INTRODUCTION
If this equipment does not operate properly, stop
work immediately and investigate the cause of the
malfunction. Maintenance work must be performed
by an experienced person, and electrical work by a
trained electrician. Do not permit untrained persons
to inspect, clean, or repair this equipment. Use
only recommended replacement parts.
NOTE
For detailed maintenance, troubleshooting, and parts
information on the power source, see Form F-14-483
(PCM-150) and supplement F-15-027 (PCM-1500), or
F-15-528 (PCM-8XL), F-15-108 (ESP-400), or F-15-
109 (ESP-600). F-15-141 (ESP-300). F-15-116 (ESP-
1000).
NOTE
Removing the nozzle from torch to check electrode
wear greatly reduces electrode life. To maximize
electrode life, only remove nozzle when changing
electrode.
4.2 REPLACING PT-19XL NOZZLE
(REFER TO FIGURE 5-1)
A. To remove nozzle, unscrew heat shield and
retaining cup, then grip the nozzle and pull
straight out.
NOTE
Always remove heat shield before removing retaining
cup. If heat shield will not loosen, tighten retaining cup
to reduce pressure on heat shield.
B. Check copper nozzle for melting from exces-
sive current, gouges from internal arcing, or
nicks and deep scratches on the O-ring seal-
ing surface. If any of these defects are visible,
replace the nozzle. (Discoloration of the inter-
nal surfaces and small black starting marks
are normal.) Hafnium particles may be re-
moved with fine sandpaper or steel wool.
C. Apply a light coating of silicone lubricant (P/N
17672-1 oz. tube) around the periphery of the
nozzle and O-ring. Make sure the O-ring (P/N
181W89) is set evenly around the shoulder of
the nozzle.

the 7/64-inch hex Allen wrench (supplied with
the torch) at the contact ring assembly (P/N
20395). Remove contact ring assembly from
the insulator body by removing one socket
head screw with a 7/64-inch hex Allen wrench.
E. Reassemble in reverse order. Align insulator
body with locating pin (P/N 996242) and push
in.
4.5 REPLACING CABLES AND HOSE
A. To disconnect the power cable, water return
hose, and gas hose at the back end of the
torch, unscrew the fiberglass sleeve (P/N
19483) from the stainless steel body.
B. The pilot arc cable is attached to connector
(P/N 20408) under insulator (P/N 20409). Re-
move tape behind the insulator so that it can be
slid up the pilot arc cable exposing the con-
nector. Loosen set screws with 7/64-inch hex
Allen wrench to remove cable from connector.
A 12-inch long 12 gauge bare copper wire is
connected to the contact ring assembly and to
the connector.
C. Straighten out the services lines and make
sure the torch sleeve is straight when screwing
it back onto the torch body. Threads are rather
fine and easy to cross-thread. Do not force the
sleeve. A little bit of silicone grease will help.
D. Secure the sleeving (P/N 995826) on the 50 ft
torch (P/N 20390) with tape or ty-wrap under
the torch sleeve to protect the service lines
from arc radiation. When the torch is ready to
operate, make sure the service lines are well
out of the way.
D. Check O-ring (P/N 86W99) inside electrode
holder periodically. If nicked, it should be
replaced exercising care to avoid scratching
the O-ring groove. Lubricate new O-ring lightly
with silicone grease before installing it into the
electrode holder.
E. Replace the gas swirl baffle if it is cracked or if
the front edge (nozzle seating surface) is
chipped.
F. When reassembling, slip the gas swirl baffle
over the electrode/electrode holder assembly.
Then screw the electrode assembly into the
torch using 7/16-inch nut driver. Tighten firmly
but do NOT overtighten.
4.4 REPLACING INSULATOR ASSEMBLY
The insulator assembly (P/N 20434) should be re-
moved periodically and inspected for cracking and for
possible replacement of six O-rings. To remove the
insulator body, do the following:
A. Remove heat shield, nozzle retaining cup,
nozzle, electrode, electrode holder, and gas
swirl baffle as described above.
B. Pull the insulator body straight out.
NOTE
The pilot arc cable will be attached, so allow plenty of
slack on the cable.
C. Lubricate the O-rings sparingly with silicone
grease. If necessary, replace O-rings.
D. If replacing the insulator body, disconnect the
pilot arc cable by loosening the setscrew with
