† Balled electrode tip ends can best be formed and maintained at these a.c. current levels.

†† Thoriated tungsten electrodes are recommended when a gas lens and high frequency starting are used.

(Exact extension is variable; from as little

as 1/8-in. for butt-welding with standard collet

bodies to 3/4-in. for corner or llet welds with

gas lens collet bodies and cups.)

f. Screw on torch cap and tighten. The cup will

press down on the collet to grip the electrode

securely. (To readjust electrode, loosen torch

cap.)

OPERATING INSTRUCTIONS

1. Make sure that all argon and water connections in

the system have been securely tightened, and that

the torch cap has been well-tightened.

2. Turn on the water. (See Page 5 for pressure and

ow requirements.)

3. With the regulator ow-adjusting valve closed, open

the shielding gas cylinder or station valve.

4. Set the power source for the desired welding cur-

rent.

5. Open all shielding gas valves downstream from

owmeter or owmeter/regulator, (valve on torch,

lever operated shut-off valve, or solenoid-operated

valve in power source).

NOTE: Purgethegashosebyallowingthegastoow-

andmoisture.Thiswillhelppreventweldcon-

tamination.

Close control switch at work position or at power source.

Draw a test arc on a heavy piece of scrap steel or

copper. (Do not use a carbon block, which will tend to

contaminate the electrode.) If the test arc is satisfactory,

commence welding.

SET-UP AND INSTALLATION

(See Figure 1)

1. Set up the torch and accessories, following Figure

1 and 2 observing all instructions supplied with

regulator/owmeter, fuse, ow switch, and shut-off

valve. (In the simplest installation, the torch gas

hose is attached directly to the owmeter outlet, and

the water hose is attached to a water line, utilizing

adaptor 11N16 supplied with torch.)

2. Connect the fuse assembly or power cable adap-

tor to the welding power source, either directly or

through available length of welding cable tted with

lugs. Run a hose from the fuse or adaptor to a water

drain.

3. Install collet body, collet, electrode, and cup on torch.

(See Figure 2). Sequence of operations:

a. Screw in collet body. (If using gas-lens, assem-

ble insulator on collet body before installing.)

b. Apply a thin coat of silicone grease to the sur-

face of the cup that mates with the torch body

and screw on the cup.

c. Remove torch cap.

d. Slide collet into position (tapered end rst).

e. Slip electrode down through hole in top of col-

let, until end of electrode extends beyond rim

of cup.

OPERATION AND MAINTENANCE HINTS

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.

1. A poor shielding gas connection, or a leaky hose,

will not only waste gas but permit the entry of min-

ute amounts of air, sufcient to contaminate both

the electrode and the weld. Trouble signs: a bluish

coat on the electrode after it has cooled, in welding

aluminum, a dark gray deposit on or beside the weld

bead.

2. Keep the torch hose away from hot metal. The

plastic hose begins to lose strength at 125° F (52°

C).

3. Do not try to repair a damaged power cable or gas

or water hose. Replace it as directed below.

4. If the torch water passages become clogged, they

can sometimes be cleared by reversing the direction

of water ow (that is, sending water in through the

power cable, out through the water hose). However,

never weld with the ow reversed. A strainer in

the water inlet line (such as P/N 96W69) is good

insurance against clogging.

5. If an electrode becomes contaminated, shut off

power, then remove electrode from torch. Break off

the contaminated end (nicking with a grinding wheel

rst will help) and replace electrode.

6. Keep an eye on the sealing “O”ring on the torch

cap. If it shows signs of wear or distortion, cut it

off. Then install a new ring (98W18). Apply a little

silicone grease to the new ring before attempting

to slide it over the cap threads.

REPLACING GAS OR WATER HOSE

1. Unscrew the torch handle and slide it back over the

service lines to expose the hose clamp (see Fig.

5).

2. Clip off the hose clamp (98W43) and remove the

hose. The rubber torch bodies do not use a clamp,

the hose is retained with ferrule nuts.

3. Clean off the barbed tting, and then brush on some

3M type 1711 adhesive onto the tting.

4. Slide the new hose clamp over the new hose.

5. Place the end of the hose in hot water for a short

time, and then slide the new hose all the way over

the tting, so it completely covers the ridges.

6. Orient the hose clamp so the tabs will not interfere

with the handle, and position the clamp so it is over

the ridges on the tting.

7. Crimp both tabs using a crimping tool or pliers (see

Fig. 3).

REPLACEMENT OF GAS LENS SCREENS IN 45V63,

995795, AND 45V64 (See Figure 4)

Large diameter gas lens collet bodies contain replace-

able screens. If plugged by spatter, replace as follows:

1. With the collet body removed from the torch, remove

the outer snap ring, P/N 54N71. This can be done

by using a small screwdriver, or an electrode with

a diameter no greater than 3/32-in. Insert the tip in

the slot on the outer sleeve of the collet body, and

pry out the snap ring.

2. Using a pair of needle nose pliers, pry out the inner

snap ring, P/N 54N69.

3. Hold the collet body with the screens down, and

gently tap the body on the work bench. The body

contains three ne and one coarse screens, sepa-

rated by spacers. If the screens are not badly fouled,

they should drop out of the body. Excessive fouling

may necessitate prying out the screens.

4. Inspect the screens and replace those which show

plugging, or other damage.

5. Replace the screens and spacers making sure that

a spacer is installed between each screen, and that

the coarsest screen is inserted last. Replace the

snap rings.
