1.2
Safety precautions
WARNING!
These Safety Precautions are for your protection. They summarise precautionary
information from the references listed in the 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 the Safety Precautions could
result in injury or death.
PROTECT YOURSELF AND OTHERS
Some welding, cutting and gouging processes are noisy and require
hearing protection. The arc, like the sun, emits ultraviolet (UV) and
other radiation and can injure the 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.
2.
3.
Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes
when welding or watching.
Always wear safety glasses with side shields in any work area, even if welding
helmets, face shields and goggles are also required.
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 look at the arc and not to expose themselves to
the rays of the electric-arc or hot metal.

4.
5.
6.
7.
Wear flameproof gauntlet-type gloves, heavy long-sleeve shirt, cuffless pants,
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.
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 the
clothing.
Protect other personnel from arc rays and hot sparks with a suitable non-flammable
partition or curtains.
Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be
hot and can fly for long distances. Bystanders should also wear goggles over safety
glasses.
FIRES AND EXPLOSIONS
The heat from flames and arcs can start fires. Hot slag or sparks can
also cause fires and explosions. Therefore:
1.
2.
3.
4.
5.
6.
7.
Protect yourself and others from flying sparks and hot metal.
Move 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 coating paper, etc.
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.
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 perform hot work on closed containers, they may
explode.
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.
Do not use equipment beyond its ratings. For example, an overloaded welding cable
can overheat and create a fire hazard.
After completing work, inspect the work area to make sure there are no hot sparks or
hot metal that could cause a fire later. Use fire watchers when necessary.
ELECTRICAL SHOCK
Contact between live electrical parts and earth 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.
2.
3.
4.
5.
6.
7.
Be sure the power source frame (chassis) is connected to the earth system of the
input power.
Connect the workpiece to a good electrical earth.
Connect the work cable to the workpiece. A poor or missing connection can expose
you or others to a fatal shock.
Use well-maintained equipment. Replace worn or damaged cables.
Keep everything dry, including clothing, work area, cables, torch/electrode holder and
power source.
Make sure that all parts of your body are insulated from both the work piece and from
the ground.
Do not stand directly on metal or the ground while working in tight quarters or a damp
area; stand on dry boards or an insulating platform and wear rubber-soled shoes.

1 SAFETY
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 earth cable.
ELECTRIC AND MAGNETIC FIELDS
May be dangerous. Electric current flowing through any conductor
causes localised Electric and Magnetic Fields (EMF). Welding and
cutting current creates EMF around welding cables and welding
machines. Therefore:
1.
2.
3.
Welders with pacemakers fitted should consult their doctor before welding. EMF may
interfere with some pacemakers.
Exposure to EMF may have other health effects which are unknown.
Welders should use the following procedures to minimise 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 the 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.
2.
3.
4.
5.
6.
Keep your head out of the fumes. Do not breathe the fumes and gases.
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 in the fumes from these materials.
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.
If you develop momentary eye, nose or throat irritation while operating, this is an
indication that the ventilation is not adequate. Stop work and take the necessary steps
to improve ventilation in the work area. Do not continue to operate if physical
discomfort persists.
Refer to ANSI/ASC Standard Z49.1 for specific ventilation recommendations.
WARNING: This product when used for welding or cutting, produces fumes or gases
that 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.

5 OPERATION
Connect the return cable to the other output on the power source. Secure the return cable’s
contact clamp to the workpiece, and make sure that there is a good contact between the
workpiece and the output for the return cable on the power source.
•
•
For TIG (GTAW) welding, the negative welding terminal (-) is used for the welding
torch and the positive welding terminal (+) is used for the return cable.
For stick (SMAW) welding, the welding cable can be connected to the positive welding
terminal (+) or negative welding terminal (-), depending on the type of electrode used.
The connection polarity is stated on the electrode packaging.
5.4
Turning the power on/off
Turn on the power by turning the switch to the “ON” (I) position.
Turn the unit off by turning the switch to the “O” position.
Whether the power supply is interrupted or the power source is switched off in the normal
manner, weld programs are stored so that they are available the next time the unit is started.
CAUTION!
Do not turn off the power source during welding (with load).
5.5
Fan control
The power source has automatic thermal control. The fan continues to run for a few minutes
after welding has stopped while the power source switches to energy-saving mode. The fan
starts again when welding restarts.
In energy-saving mode, the fan starts occasionally and runs for a few minutes.
5.6
Thermal protection
The power source includes thermal protection against overheating. When
overheating occurs, welding stops, the overheating indicator on the panel
illuminates, and an error message appears on the display screen. The protection
is automatically reset once the temperature has decreased to a safe level.
5.7
Functions and symbols
Stick (SMAW) welding
Stick (SMAW) welding can also be referred to as welding with coated electrodes.
Striking the arc melts the electrode, and its coating forms protective slag.
For Stick (SMAW) welding, the power source must be supplemented with the following:
•
•
Welding cable with electrode holder
Return cable with clamp
Soft/Crisp
The arc force function determines how the current changes in response to
variations in arc length during welding. Use a low value (Soft) to get a calm arc
with little spatter, and use a high value (Crisp) to get a hot and digging arc.
Soft/Crisp only applies to stick (SMAW) welding.

5 OPERATION
Cel 6010
Optimized arc characteristics for cellulose electrodes, such as 6010.
TIG (GTAW) welding
TIG welding, also called gas tungsten arc welding (GTAW), melts the metal of
the workpiece using an arc struck from a tungsten electrode that does not melt.
The weld pool and electrode are protected by shielding gas.
For TIG (GTAW) welding, the welding power source must be supplemented with
the following:
•
•
•
•
TIG (GTAW) torch with gas valve
Argon gas cylinder
Argon gas regulator
Tungsten electrode
This power source performs Live TIG (GTAW) start.
The tungsten electrode is placed against the workpiece. When lifted from
workpiece, the arc is struck at a limited current level.
Voltage Reduction Device (VRD)
The VRD function ensures that the open-circuit voltage does not exceed 35 V
when welding is not being carried out. This is indicated by a lit VRD indicator on
the panel. Contact an authorized ESAB service technician to activate this
function.
