General Safety

PROTECT yourself and others. Read and understand this information.

1. Before use, read and understand manufacturer′s

instructions, Material Safety Data Sheets

(MSDS′s), employer′s Safety practices,

ANSI Z49.1, and welder instructions.

2. Keep out of reach of children.
Keep children and bystanders away while operating.

3. Place the welder on a stable location before use.
If it falls while plugged in, severe injury,
electric shock, or fire may result.

4. Do not overreach.

Keep proper footing and balance at all times.

5. Stay alert, watch what you are doing and use
common sense when operating a welder.
Do not use a welder while you are tired or under
the influence of drugs, alcohol or medication.

A moment of inattention while operating welders
may result in serious personal injury.

6. Avoid unintentional starting. Make sure you are
prepared to begin work before turning on the Welder.

7. Never leave the Welder unattended while
energized. Turn power off if you have to leave.

8. The warnings, precautions, and instructions

discussed in this instruction manual cannot
cover all possible conditions and situations
that may occur. It must be understood by the

operator that common sense and caution are
factors which cannot be built into this product,
but must be supplied by the operator.

9. WARNING: This product, when used for welding,
plasma cutting, soldering, or similar applications,
produces chemicals known to the State of
California to cause cancer and birth defects
or other reproductive harm. (California Health
& Safety Code § 25249.5, et seq.)

10. WARNING: The cord of this product contains
lead and/or di (2-ethylhexyl) phthalate (DEHP),
chemicals known to the State of California
to cause cancer, and birth defects or other
reproductive harm. Wash hands after handling.
(California Health & Safety Code § 25249.5, et seq.)

11. Exposure to welding or cutting exhaust

fumes can increase the risk of developing
certain cancers, such as cancer of the
larynx and lung cancer. Also, some diseases

that may be linked to exposure to welding
or plasma cutting exhaust fumes are:

• Early onset of Parkinson’s Disease

• Heart disease

• Ulcers

• Damage to the reproductive organs

• Inflammation of the small intestine or stomach

• Kidney damage

• Respiratory diseases such as emphysema,
bronchitis, or pneumonia

Use natural or forced air ventilation and wear
a respirator approved by NIOSH to protect
against the fumes produced to reduce the
risk of developing the above illnesses.

12. Do not use near degreasing or

painting operations.

13. Keep head out of fumes.
Do not breathe exhaust fumes.

14. Use enough ventilation, exhaust at arc, or

both, to keep fumes and gases from breathing
zone and general area. If engineering controls

are not feasible, use an approved respirator.

15. Work in a confined area only if it

is well-ventilated, or while wearing
an air-supplied respirator.

16. Have a recognized specialist in
Industrial Hygiene or Environmental Services
check the operation and air quality
and make recommendations
for the specific welding situation.

Follow OSHA guidelines for
Permissible Exposure Limits (PEL’s) and
the American Conference of Governmental
Industrial Hygienists recommendations for
Threshold Limit Values (TLV’s) for fumes and gases.

17. Wear ANSI-approved welding eye protection

featuring at least a number 10 shade lens rating.

18. Wear leather leggings, fire resistant shoes
or boots during use. Do not wear pants with

cuffs, shirts with open pockets, or any clothing
that can catch and hold molten metal or sparks.

19. Keep clothing free of grease, oil,

solvents, or any flammable substances.

Wear dry, insulating gloves and protective clothing.

20. Wear an approved head covering to protect
the head and neck. Use aprons, cape, sleeves,
shoulder covers, and bibs designed and
approved for welding and cutting procedures.

21. Wear an approved welding jacket or long sleeves

to protect forearms from radiation burns.

22. When welding/cutting overhead or in confined
spaces, wear flame resistant ear plugs or
ear muffs to keep sparks out of ears.

23. Turn off, disconnect power, and
discharge electrode to ground before
setting down torch/electrode holder and
before installing TIG torch to welder.

24. Turn off, disconnect power, and
discharge electrode to ground before setting
down torch/electrode holder and before service.

25. Do not touch energized electrical parts.
Wear dry, insulating gloves. Do not touch electrode
holder, electrode, welding torch, or welding wire with
bare hand. Do not wear wet or damaged gloves.

26. Do not use near water or damp objects.

27. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields
in close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.

28. Do not expose welders to rain or wet conditions.
Water entering a welder will increase
the risk of electric shock.

29. Do not use outdoors.

30. Insulate yourself from the workpiece and ground.
Use nonflammable, dry insulating material if possible,
or use dry rubber mats, dry wood or plywood, or
other dry insulating material large enough to cover
your full area of contact with the work or ground.

31. Clear away or protect flammable objects.
Remove or make safe all combustible materials for a
radius of 35 feet (10 meters) around the work area.
Use a fire resistant material to cover or block all open
doorways, windows, cracks, and other openings.

32. Keep ABC-type fire extinguisher near

work area and know how to use it.

33. Maintain a safe working environment.
Keep the work area well lit.
Make sure there is adequate surrounding workspace.
Keep the work area free of obstructions,
grease, oil, trash, and other debris.

34. Do not operate welders in atmospheres

containing dangerously reactive or
flammable liquids, gases, vapors, or dust.

Provide adequate ventilation in work areas
to prevent accumulation of such substances.

Welders create sparks which may ignite flammable
substances or make reactive fumes toxic.

35. If working on a metal wall, ceiling, etc.,

prevent ignition of combustibles on the
other side by moving the combustibles to a
safe location. If relocation of combustibles is

not possible, designate someone to serve as
a fire watch, equipped with a fire extinguisher,
during the cutting process and for at least one
half hour after the cutting is completed.

36. Do not weld or cut on materials having

a combustible coating or combustible
internal structure, as in walls or ceilings, without
an approved method for eliminating the hazard.

37. Do not dispose of hot slag in containers
holding combustible materials.

38. After welding, make a thorough examination
for evidence of fire. Be aware that easily

visible smoke or flame may not be present
for some time after the fire has started.

39. Do not apply heat to a container that has held

an unknown substance or a combustible
material whose contents, when heated,
can produce flammable or explosive vapors.

Clean and purge containers before applying heat.
Vent closed containers, including castings,
before preheating, welding, or cutting.

40. Unplug before maintenance. Unplug the Welder
from its electrical outlet before any inspection,
maintenance, or cleaning procedures.

Gas Shielded Welding - Cylinder Safety

Cylinders can explode when damaged.

1. Do not weld on a pressurized or closed cylinder.

2. Do not allow an electrode holder,

electrode, welding torch, or welding
wire to touch the cylinder.

3. Keep cylinders away from any electrical circuits,
including welding circuits.

4. Keep protective cap in place over the valve
except when the cylinder is in use.

5. Use only correct gas shielding equipment
designed specifically for the type of welding
you will do. Maintain this equipment properly.

6. Protect gas cylinders from heat, being struck,
physical damage, slag, flames, sparks, and arcs.

7. Use proper procedures to move cylinders.
