SECTION 3

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.

DANGER

NOTE

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.

INSTALLATION AND OPERATION

Cutting Data PT-19XL W/Air (50 AMPS)

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

HAND TIGHTNESS. The nozzle will seat

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

inches

4 1/4

inches

SLEEVING

NOTE: Braid does not go over Gas or (P/N - 72020003) Hose.

Securely tape around hose bundle 2" wide.

Slide braid down and tape over 4-1/4".
