1.1 Meaning of symbols
As used throughout this manual: Means Attention! Be Alert!
1.2 Safety precautions
WARNING!
These Safety Precautions are for your protection. They summarise precautionary
information from the references listed in Additional Safety Information section. Before
performing 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 equipment is essential to prevent accidents. Therefore:
1. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when
welding or watching.
2. Always wear safety glasses with side shields in any work area, even if welding helmets face
shields and goggles are also required.
3. 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.
4. Wear flameproof gauntlet type gloves, heavy long-sleeve shirt, cuff less trousers, high-topped
shoes and a welding helmet or cap for 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.
5. 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.
6. Protect other personnel from arc rays and hot sparks with a suitable non-flammable partition or
curtains.
7. Use goggles over safety glasses when chipping slag or grinding. Chipped slag maybe hot and
can fly far. Bystanders should also wear goggles over safety glasses.
DANGER!
Means immediate hazards which, if not avoided, will result in immediate, serious
personal injury or loss of life.
WARNING!
Means potential hazards which could result in personal injury or loss of life.
CAUTION!
Means hazards which could result in minor personal injury.
WARNING!
Before use, read and understand the instruction manual and
follow all labels, employer´s safety practices and Safety Data
Sheets (SDSs).

0463 815 101 - 5 - © ESAB AB 2021
FIRES AND EXPLOSIONS
Heat from flames and arcs can start fires. Hot slag or sparks can also cause
fires and explosions. Therefore:
1. Protect yourself and others from flying sparks and hot metal.
2. Remove all combustible materials 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.
3. 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.
4. Do not weld, cut or perform other hot work until the work piece has been completely cleaned
so that there are no substances on the work piece which might produce flammable or toxic
vapors. Do not do hot work on closed containers, they may explode.
5. 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.
6. Do not use equipment beyond its ratings. For example, an overloaded welding cable can
overheat and create a fire hazard.
7. 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.
ELECTRICAL SHOCK
Contact with live electrical parts and ground can cause severe injury or
death. DO NOT use AC welding current in damp areas, if movement is
confined, or if there is danger of falling. Therefore:
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 damaged 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 both the work piece and from the
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 for specific grounding recommendations. Do not mistake
the work lead for a ground cable.

0463 815 101 - 6 - © ESAB AB 2021
ELECTRIC AND MAGNETIC FIELDS
May be dangerous. Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). Welding 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 minimise exposure to EMF:
1. Route the electrode and work cables together. Secure them with tape when possible.
2. Never coil the torch or work cable around your body.
3. Do not place your body between the torch and work cables. Route cables on the same
side of your body.
4. Connect the work cable to the workpiece as close as possible to the area being welded.
5. Keep welding power source and cables as far away from your body as possible.
FUMES AND GASES
Fumes and gases, can cause discomfort or harm, particularly in confined
spaces. Shielding gases can cause asphyxiation. Therefore:
1. Keep your head out of the fumes. Do not breathe the fumes and gases.
2. 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.
3. Do not operate near degreasing and spraying operations. The heat or arc can react with
chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas and other irritant gases.
4. 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.
5. Refer to ANSI/ASC Standard Z49.1 for specific ventilation recommendations.
6. WARNING: This product when used for welding or cutting, produces fumes or gases which
contain chemicals known to the State of California to cause birth defects and in some cases
cancer (California Health & Safety Code §25249.5 et seq.)
CYLINDER HANDLING
Cylinders, if mishandled, can rupture and violently release gas. A sudden
rupture of cylinder valve or relief device can injure or kill. Therefore:
1. Locate cylinders away from heat, sparks and flames. Never strike an arc on a cylinder.
2. 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 compressed gas cylinder.
3. Always secure cylinders in an upright position by chain or strap to suitable hand trucks,
undercarriages, benches, wall, post or racks. Never secure cylinders to work tables or fixtures
where they may become part of an electrical circuit.
4. 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.

below.
To install wire spool, refer to the steps below.
Figure 12: 12.5 lb (8 in.) spool installation
1 Wire spool hub nut 5 12.5 lb (8 in.) wire spool
2 Flat washer small hole 6 Spool hub
3 Spring small hole
4 Plastic nut
1) Remove wire spool hub retaining clip. Grasp the loop and pull.
2) Place wire spool onto the hub, loading it so that the wire will feed off the bottom of the spool
as the spool rotates counter clockwise. Make sure to align the spool alignment pin on the hub
with the mating hole in the wire spool.
3) Replace the wire spool hub retaining clip in the set of holes closest to the spool.
NOTE!
The hub tension has been pre-adjusted at the factory. However if adjustment is
required, see the "Wire reel brake" section.
CAUTION!
Use care in handling the spooled wire as it will tend to “unravel” when loosened from
the spool. Grasp the end of the wire firmly and don’t let go of it.

4.3Inserting wire into the wire feed mechanism
Release the tension from the pressure roller by turning the adjustable wire drive tension knob (1)
in a counter clockwise direction. Then to release the pressure roller arm (2) push the tension
screw toward the back of the machine which releases the pressure roller arm (2). With the MIG
welding wire feeding from the bottom of the spool, see pass the electrode wire through the inlet
guide (4), between the rollers, through the outlet guide (3) and into the MIG gun. Resecure the
pressure roller arm (2) and wire drive tension screw and adjust the pressure accordingly. Remove
the contact tip from the MIG gun. With the MIG gun lead reasonably straight, feed the wire
through the MIG gun by pressing the trigger switch. Fit the appropriate velocity contact tip.
WARNING!
Before connecting the work clamp to the workpiece make sure the electricity supply is
switched off. The electrode wire will be at welding voltage potential while it is being
feed through the system. Keep the MIG gun away from eyes and face.

General safety regulations for handling the equipment can be found in the "SAFETY"
chapter of this manual. Read it through before you start using the equipment!
5.1 Victor regulator
Pressure regulator attached to the cylinder valve reduce high cylinder pressures to suitable low
working pressures for welding, cutting, and other applications.
Figure 16: Victor regulator
1 Low pressure gauge (delivery)
2 High pressure gauge (supply)
3 Outlet connection
4 Pressure adjusting screw
5 Inlet connection
WARNING!
Use the regulator for the gas and pressure for which it is designed. Never alter a
regulator for use with any other gas.
Regulators purchased with open 1/8 in., 1/4 in., 3/8 in., or 1/2 in. NPT ports must be assembled to
their intended system.
1. Note the maximum inlet pressure stamped on the regulator. DO NOT attach the regulator to a
system that has a higher pressure than the maximum rated pressure stamped on the
regulator.
2. The regulator body will be stamped “IN” or “HP” at the inlet port. Attach the inlet port to the
system supply pressure connection.
3. If gauges are to be attached to the regulator and the regulator is stamped and listed by a third
party (i.e. “UL” or “ETL”). The following requirements must be met:
•Inlet gauges over 1000 PSIG (6.87 mPa) shall conform with the requirements of UL
404, “Indicating Pressure Gauges for Compressed Gas Service.”
•Low pressure gauges must be UL recognized for the class of regulator they are being
used on according to UL252A.
WARNING!
Do not use a regulator that delivers pressure exceeding the pressure rating of the
downstream equipment unless provisions are made to prevent over-pressurization
(i.e. system relief valve). Make sure the pressure rating of the downstream
equipment is compatible with the maximum delivery pressure of the regulator.

4. Be sure that the regulator has the correct pressure rating and gas service for the cylinder
used.
NOTE!
For MIG application, the gas mixture used is 80% argon and 20% carbon dioxide.
For MAG application, 100% carbon dioxide is used.
5. Carefully inspect the regulator for damaged threads, dirt, dust, grease, oil, or other flammable
substances. Remove dust and dirt with a clean cloth. Be sure the inlet swivel filter is clean and
in place. Attach the regulator to the cylinder valve. Tighten securely with a wrench.
WARNING!
Do not attach or use the regulator if oil, grease, flammable substances or damage is
present! Have a qualified repair technician clean the regulator or repair any damage.
Figure 17: Regulator to cylinder valve
6. Before opening the cylinder valve, turn the regulator adjusting screw counter-clockwise until
there is no pressure on the adjusting spring and the screw turns freely.
7. Relief valve (where provided): The relief valve is designed to protect the low pressure side of
the regulator from high pressures. Relief valves are not intended to protect downstream
equipment from high pressures.
WARNING!
Do not tamper with the relief valve or remove it from the regulator.
WARNING!
Stand to the side of the cylinder opposite the regulator when opening the cylinder valve.
Keep the cylinder valve between you and the regulator. For your safety, never stand in
front of or behind a regulator when opening the cylinder valve!
