SAFETY INSTRUCTIONS AND WARNINGS
SECTION 1:
SAFETY INSTRUCTIONS AND WARNINGS
!
!
WARNING
SERIOUS INJURY OR DEATH may result if welding and cutting equipment is not properly installed, used and maintained.
Misuse of this equipment and other unsafe practices can be hazardous. The operator, supervisor, and helper must
read and understand the following safety warnings and instructions before installing or using any welding or cutting
equipment.
The welding and cutting process is used in many potentially dangerous environments such as elevated heights, areas
of limited ventilation, close quarters, around water, in hostile environments, etc., and it is important that the operator(s)
are aware of the dangers associated with working in these types of conditions. Be certain that the operator(s) are
trained in safe practices for environments in which they are expected to work and under competent supervision.
It is essential that the operator, supervisor and all other personnel in the work area are aware of the dangers of the
welding or cutting process. Training and proper supervision are important for a safe work place. Keep these instructions
for future use. Additional recommended safety and operating information is referenced in each section.
1.01 Welding Hazards
WARNING
electric shocK can cause injury or
death.
install and maintain equipment in
accordance With the national electrical
code (nfpa 70) and local codes. do not
service or repair equipment With poWer
on. do not operate equipment With
protective insulators or covers removed.
service or repair to equipment must be
done by a qualified repair technician, or
trained personnel only.
1.
Do not touch live electrical parts.
2.
Do not touch an electrode with bare skin and electrical
ground at the same time.
3. Always keep welding gloves dry and in good condition.
NOTE
Aluminized protective clothing can become part
of the electrical path.
4. Keep oxygen cylinders, chains, wire ropes, cranes, hoists,
and elevators away from any part of the electrical path.
5. All ground connections must be checked periodically
to determine that they are mechanically strong and
electrically adequate for the required current.
6. When engaged in alternating current, welding or cutting
under wet conditions or warm surroundings where
perspiration is a factor, the use of reliable automatic
controls for reducing the no-load voltage is recommended
to reduce shock hazard.
7. When the welding or cutting process requires values of
open circuit voltages in alternating current machines
higher than 80 volts, and direct current machines higher
than 100 volts, means must be provided to prevent the
operator from making accidental contact with the high
voltage by adequate insulation or other means.
8. When welding is to be suspended for any substantial
length of time, such as during lunch or overnight, all
electrodes should be removed from the electrode
holder and the electrode holder carefully located so that
accidental contact cannot occur.
9. The holder must be disconnected from the power source
when not in use.
10. Never immerse Mig-Guns, electrode holders, tig torches,
plasma torches, or electrodes in water.
WARNING
smoKe, fumes and gases can be dangerous
to your health.
11. Keep smoke, fumes, and gases from the breathing
area.
12. Fumes from the welding or cutting process are of various
types and strengths, depending on the kind of base metal
being worked on. To ensure your safety, do not breathe
these fumes.
13. Ventilation must be adequate to remove smoke, fumes,
and gases during the operation to protect operators and
other personnel in the area.

SAFETY INSTRUCTIONS AND WARNINGS
14. Vapors of chlorinated solvents can form the toxic gas
“Phosgene” when exposed to ultraviolet radiation from
an electric arc. All solvents, degreasers and potential
sources of these vapors must be removed from the work
area.
15. Fumes produced by welding or cutting, particularly in
confined places, can cause discomfort and physical harm
if inhaled over an extended period of time.
16. Provide adequate ventilation in the welding or cutting
area. Use air-supplied respirators if ventilation is not
adequate to remove all fumes and gases. Never ventilate
with oxygen. Oxygen supports and vigorously accelerates
fire.
WARNING
arc rays, hot slag, and sparKs can injure
eyes and burn sKin .
17. The welding and cutting processes produce extreme
localized heat and strong ultraviolet rays.
18. Never attempt to weld or cut without a welding helmet
with the proper lens. Ensure that the lens complies with
federal guidelines. A number 12 to 14 shade filter lens
provides the best protection against arc radiation. When
in a confined area, prevent the reflected arc rays from
entering around the helmet.
19. Ensure all personnel in the work area are protected from
arc rays and sparks. Approved shielding curtains and
appropriate goggles should be used to provide protection
to staff in the surrounding area and operators of nearby
equipment.
20. Unprotected skin should also be covered from arc rays,
heat and molten metal. Always wear protective gloves
and clothing that does not allow skin to become exposed.
All pockets should be closed and cuffs sewn shut. Leather
aprons, sleeves, leggings, etc., should be worn for out-of-
position welding and cutting or for heavy operations using
large electrodes. High top work shoes provide adequate
protection from foot burns. For added protection use
leather spats.
21. Flammable hair preparations should not be used when
welding or cutting. Wear ear plugs to protect ears from
sparks.
22. Where the work area permits, the operator should be
enclosed in an individual booth painted with a finish of
low reflectivity such as zinc oxide. This is an important
factor for absorbing ultraviolet radiations, and lamp black.
The operator should be enclosed with non-combustible
screens similarly painted.
WARNING
Welding sparKs can cause fires and
eXplosions.
23. Causes of fire and explosion are: combustibles reached by
the arc, flame, flying sparks, hot slag or heated material.
Remove combustibles from the work area and/or provide
a fire watch.
24. Avoid oily or greasy clothing as sparks may ignite them.
Have a fire extinguisher nearby, and know how to use
it.
25. Be alert to the danger of conduction or radiation. For
example, if welding or cutting is to be done on a metal
wall, partition, ceiling, or roof, precautions must be taken
to prevent ignition of combustibles on the other side.
26. Do not weld or cut containers that have held combustibles.
All hollow spaces, cavities, and containers should be
vented prior to welding or cutting to permit the escape
of air or gases. Purging with inert gas is recommended.
27. Never use oxygen in a welding torch. Use only inert gases
or inert gas mixes as required by the process. Use of
combustible compressed gases can cause explosions
resulting in personal injury or death. Arcing against any
compressed gas cylinder can cause cylinder damage or
explosion.
WARNING
noise can damage hearing.
28. Noise from the air carbon-arc process can damage
your hearing. Wear protective hearing devices to ensure
protection when noise levels exceed OSHA standards.
Adequate hearing protection devices must be worn by
operators and surrounding personnel to ensure personal
protection against noise.

MAINTENANCE
Contact tips and nozzles should be cleaned frequently. Spatter
buildup may cause bridging between nozzle and tip. This
could cause electrical shorting between the nozzle and work
piece as well as restricting gas flow.
Regularly inspect the conductor tube, torch and cable
assembly for abrasions, cuts, and undue wear. Replace or
repair any parts as needed.
The torch and conductor tube assemblies have o-rings for
seals. Lubrication of these o-rings should be done periodically
and periodical inspections should be made to ensure that the
o-rings do not de-grade, allowing water and/or shielding gas
leaks to occur. When removing the conductor tube from the
torch assembly, be sure the single o-ring located in the bottom
of the hole remains in place.
