WARNING: These Safety Precautions are for
your protection. They summarize precautionary
information from the references listed in Addi-
tional Safety Information section. Before per-
forming any installation or operating procedures,
be sure to read and follow the safety precautions listed below
as well as all other manuals, material safety data sheets,
labels, etc. Failure to observe Safety Precautions can result
in injury or death.
PROTECT YOURSELF AND OTHERS -
-
Some welding, cutting, and gouging
processes are noisy and require ear
protection. The arc, like the sun, emits
ultraviolet (UV) and other radiation and
can injure skin and eyes. Hot metal can cause burns.
Training in the proper use of the processes and equip-
ment is essential to prevent accidents. Therefore:
1. Always wear safety glasses with side shields in any work
area, even if welding helmets, face shields, and goggles
are also required.
2. Use a face shield fitted with the correct filter and cover
plates to protect your eyes, face, neck, and ears from
sparks and rays of the arc when operating or observing
operations. Warn bystanders not to watch the arc and not
to expose themselves to the rays of the electric-arc or hot
metal.
3. Wear flameproof gauntlet type gloves, heavy long-sleeve
shirt, cuffless trousers, high-topped shoes, and a welding
helmet or cap for hair protection, to protect against arc rays
and hot sparks or hot metal. A flameproof apron may also
be desirable as protection against radiated heat and sparks.
4. Hot sparks or metal can lodge in rolled up sleeves, trouser
cuffs, or pockets. Sleeves and collars should be kept
buttoned, and open pockets eliminated from the front of
clothing
5. Protect other personnel from arc rays and hot sparks with
a suitable non-flammable partition or curtains.
6. Use goggles over safety glasses when chipping slag or
grinding. Chipped slag may be hot and can fly far. Bystand-
ers should also wear goggles over safety glasses.
FIRES AND EXPLOSIONS -- Heat from
flames and arcs can start fires. Hot slag
or sparks can also cause fires and ex-
plosions. Therefore:
1. Remove all combustible materi-
als well away from the work area or cover the materials
with a protective non-flammable covering. Combustible
materials include wood, cloth, sawdust, liquid and gas
fuels, solvents, paints and coatings, paper, etc.
2. Hot sparks or hot metal can fall through cracks or crevices
in floors or wall openings and cause a hidden smoldering
fire or fires on the floor below. Make certain that such
openings are protected from hot sparks and metal.“
3. Do not weld, cut or perform other hot work until the
workpiece has been completely cleaned so that there are
no substances on the workpiece which might produce
flammable or toxic vapors. Do not do hot work on closed
containers. They may explode.
4. Have fire extinguishing equipment handy for instant use,
such as a garden hose, water pail, sand bucket, or
portable fire extinguisher. Be sure you are trained in its
use.
11/95
5. Do not use equipment beyond its ratings. For example,
overloaded welding cable can overheat and create a fire
hazard.
6. After completing operations, inspect the work area to make
certain there are no hot sparks or hot metal which could
cause a later fire. Use fire watchers when necessary.
7. For additional information, refer to NFPA Standard 51B,
"Fire Prevention in Use of Cutting and Welding Processes",
available from the National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269.
ELECTRICAL SHOCK -- Contact with live
electrical parts and ground can cause se-
vere injury or death. DO NOT use AC weld-
ing current in damp areas, if movement is
confined, or if there is danger of falling.
1. Be sure the power source frame (chassis) is connected to
the ground system of the input power.
2. Connect the workpiece to a good electrical ground.
3. Connect the work cable to the workpiece. A poor or
missing connection can expose you or others to a fatal
shock.
4. Use well-maintained equipment. Replace worn or dam-
aged cables.
5. Keep everything dry, including clothing, work area, cables,
torch/electrode holder, and power source.
6. Make sure that all parts of your body are insulated from
work and from ground.
7. Do not stand directly on metal or the earth while working in
tight quarters or a damp area; stand on dry boards or an
insulating platform and wear rubber-soled shoes.
8. Put on dry, hole-free gloves before turning on the power.
9. Turn off the power before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 (listed on next page)
for specific grounding recommendations. Do not mistake
the work lead for a ground cable.
ELECTRIC AND MAGNETIC FIELDS — May
be dangerous. Electric current flowing
through any conductor causes localized
Electric and Magnetic Fields (EMF). Weld-
ing and cutting current creates EMF around
welding cables and welding machines.
Therefore:
1. Welders having pacemakers should consult their physician
before welding. EMF may interfere with some pacemakers.
2. Exposure to EMF may have other health effects which are
unknown.
3. Welders should use the following procedures to minimize
exposure to EMF:
A. Route the electrode and work cables together. Secure
them with tape when possible.
B. Never coil the torch or work cable around your body.
C. Do not place your body between the torch and work
cables. Route cables on the same side of your body.
D. Connect the work cable to the workpiece as close as
possible to the area being welded.
E. Keep welding power source and cables as far away from
your body as possible.
SAFETY PRECAUTIONS
6
FUMES AND GASES -- Fumes and
gases, can cause discomfort or harm,
particularly in confined spaces. Do
not breathe fumes and gases. Shield-
ing gases can cause asphyxiation.
Therefore:
1. Always provide adequate ventilation in the work area by
natural or mechanical means. Do not weld, cut, or gouge
on materials such as galvanized steel, stainless steel,
copper, zinc, lead, beryllium, or cadmium unless positive
mechanical ventilation is provided. Do not breathe fumes
from these materials.
2. Do not operate near degreasing and spraying operations.
The heat or arc rays can react with chlorinated hydrocar-
bon vapors to form phosgene, a highly toxic gas, and other
irritant gases.
3. If you develop momentary eye, nose, or throat irritation
while operating, this is an indication that ventilation is not
adequate. Stop work and take necessary steps to improve
ventilation in the work area. Do not continue to operate if
physical discomfort persists.
4. Refer to ANSI/ASC Standard Z49.1 (see listing below) for
specific ventilation recommendations.
CYLINDER HANDLING -- Cylinders, if
mishandled, can rupture and violently
release gas. Sudden rupture of cylin-
der, valve, or relief device can injure
or kill. Therefore:
1. Use the proper gas for the process and use the proper
pressure reducing regulator designed to operate from the
compressed gas cylinder. Do not use adaptors. Maintain
hoses and fittings in good condition. Follow manufacturer's
operating instructions for mounting regulator to a com-
pressed gas cylinder.
2. Always secure cylinders in an upright position by chain or
strap to suitable hand trucks, undercarriages, benches,
walls, post, or racks. Never secure cylinders to work
tables or fixtures where they may become part of an
electrical circuit.
3. When not in use, keep cylinder valves closed. Have valve
protection cap in place if regulator is not connected.
Secure and move cylinders by using suitable hand trucks.
Avoid rough handling of cylinders.
4. Locate cylinders away from heat, sparks, and flames.
Never strike an arc on a cylinder.
5. For additional information, refer to CGA Standard P-1,
"Precautions for Safe Handling of Compressed Gases in
Cylinders", which is available from Compressed Gas
Association, 1235 Jefferson Davis Highway, Arlington,
VA 22202.
EQUIPMENT MAINTENANCE -- Faulty or im-
properly maintained equipment can cause
injury or death. Therefore:
1. Always have qualified personnel perform the installation,
troubleshooting, and maintenance work. Do not perform
any electrical work unless you are qualified to perform
such work.
Used to call attention to immediate haz-
ards which, if not avoided, will result in
immediate, serious personal injury or loss
of life.
Used to call attention to potential hazards
which could result in personal injury or
loss of life.
Used to call attention to hazards which
could result in minor personal injury.
2. Before performing any maintenance work inside a power
source, disconnect the power source from the incoming
electrical power.
3. Maintain cables, grounding wire, connections, power cord,
and power supply in safe working order. Do not operate any
equipment in faulty condition.
4. Do not abuse any equipment or accessories. Keep equip-
ment away from heat sources such as furnaces, wet condi-
tions such as water puddles, oil or grease, corrosive atmo-
spheres and inclement weather.
5. Keep all safety devices and cabinet covers in position and
in good repair.
6. Use equipment only for its intended purpose. Do not modify
it in any manner.

2.1 Setup and Installation
A. Connect the regulator/flowmeter to a gas cylinder. Refer to the
instructions supplied with the regulator/flowmeter for details on
attaching and adjusting the regulator.
B. Connect one end of the gas hose (40V77 or 34V38) to the regulator
outlet and the other end to the torch cable adaptor (105Z57).
C. Connect the power cable adaptor to the welding power source,
either directly or through a suitable length of welding cable fitted with
lugs.
D. Install collet body, collet, electrode, and cup on torch (see Figure
2-1) as follows:
1. Screw in collet body. (If using a gas lens, assemble insulator
on collet body before installing.)
2. Apply a thin coat of silicone grease to the surface of the cup that
mates with the torch body and then screw on cup.
3. Remove torch cap and slide collet into position (tapered end
first).
4. Slip electrode down through hole in top of collet until end of
electrode extends beyond rim of cup. (Exact extension varies
from 1/8 inch for butt welding with standard collet bodies to
3/4 inch or more for corner or fillet welds with gas lens collet
bodies and cups).
5. Screw on the torch cap and tighten. The cap will press down
on the collet to grip the electrode securely. To readjust
electrode, loosen torch cap.
SECTION 2 INSTALLATION
NOTE
When using high frequency with
sleeved high- impact cups, arcing
may sometimes occur between
the electrode and the steel sleeve.
To avoid this, it is advantageous
to extend the electrode as far as
possible consistent with the par-
ticular application.

2.2 Operating Instructions
A. Make sure that all gas connections in the system and the torch cap
have been securely tightened.
B. With the regulator flow-adjusting valve closed, open the gas
cylinder or station valve.
C. Set the power source for the desired welding current.
D. Open all shielding gas valves downstream from the flowmeter or
flowmeter/regulator (e.g., valve on torch, lever-operated shutoff
valve, or solenoid-operated valve in power source).
E. Set shielding gas flow to the desired level, as registered on
flowmeter tube or gauge.
NOTE
Purge the gas hose by allowing the
gas to flow long enough (up to 15
minutes on new torch; less than 5
minutes thereafter) to drive out air
and moisture. This will help prevent
weld contamination.
2.3 Installation of Argon Shutoff Valve
Referring to Figure 2-2, install argon shutoff valve (17732) on HW-17
phenolic body torch originally supplied without valve (16X48, 16X50, or
634720) as follows:
A. Remove and discard the torch handle (105Z55).
B. Remove the power cable from the torch body.
C. Screw the front handle (12N06) of the argon valve to the torch body.
D. Remove the rear handle (17731) from the argon valve.
E. Assemble valve body (17729) to torch body.
F. Pass the power cable through the rear handle and attach it to the
valve body (17729).
G. Screw the rear handle to the valve body.

3.1 Maintenance
A. A poor shielding gas connection, or a leaky hose, will not only waste
gas but permit the entry of minute amounts of air, sufficient to
contaminate both the electrode and the weld. Trouble signs: a
bluish cast on the electrode after it has cooled; in welding aluminum,
a dark gray deposit on or beside the weld bead.
B. Keep the torch hose away from hot metal.
C. Do not try to repair concentric power cable, it should be replaced.
Two piece cable and hose assemblies may be repaired using the
repair kits noted in parts breakdown. The kits include replacement
fittings and lugs for the cable and hose.
D. If an electrode becomes contaminated, shut off power, then remove
electrode from torch. Break off the contaminated end (nicking with
a grinding wheel first will help) and replace electrode.
E. Periodically check on the sealing "O" ring on the torch cap. If it
shows signs of wear or distortion, cut it off. Then install new "O" ring
(181W53) using the assembly tool (13N42) supplied with the torch.
Apply a small amount of silicone grease to the new "O" ring before
attempting to slide it over the tool and into the cap groove.
SECTION 3 MAINTENANCE
If this equipment does not operate prop-
erly, stop work immediately and investi-
gate the cause of the malfunction. main-
tenance 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 recom-
mended replacement parts.

3.2 Replacement of Gas Lens Screens (See Figure 3-1)
If screens are plugged by spatter, replace as follows:
A. With the collet body removed from the torch, remove the outer snap-
ring (54N71). This can be done by using a small screwdriver, or an
electrode with a diameter no greater than 3/32". Insert the tip in the
slot on the outer sleeve of the collet body, and pry out the snapring.
B. Using a pair of needle nose pliers, pry out the inner snapring
(54N69).
SECTION 3 MAINTENANCE
Figure 3-1. Replaceable Parts in Collet Bodies 45V63, 995795,
and 45V64
C. Hold the collet body with the screens down, and gently tap the body
on the work bench. The body contains three fine and one coarse
screens, separated by spacers. If the screens are not badly fouled,
they should drop out of the body. Excessive fouling may necessi-
tate prying out the screens.
D. Inspect the screens and replace those which show plugging or other
damage.
E. 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 snaprings.
