SECTION 1: Arc Welding Safety Instructions and Warnings
!
WARNING
ARC WElDING can be hazardous.
Protect yourself and others from possible serious injury or death. Keep children away. Do not lose these instructions. Read
operating / instruction manual before installing, operating or servicing this product.
Welding products and welding processes can cause serious injury or death, or damage to other equipment or property, if the operator does not strictly observe all safety
rules and take precautionary actions.
Safe practices have developed from past experience in the use of welding and cutting. These practices must be learned through study and training before using this
equipment. Anyone not having extensive training in welding and cutting practices should not attempt to weld. Certain practices apply to equipment connected to power
lines; other practices apply to engine driven equipment.
Safe practices are outlined in the American National Standard Z49.1 entitled: SAFETY IN WELDING AND CUTTING. This publication and other guides to what you should
learn before operating this equipment are listed at the end of these safety precautions.

1.01 Safety Instructions
ElECTRIC SHOCk can kill.
Touching live electrical parts can cause fatal shocks or severe
burns. The electrode and work circuit is electrically live whenever
the output is on. The input power circuit and machine internal cir-
cuits are also live when power is on. In semiautomatic or automatic
wire welding, the wire, wire reel, drive roll housing, and all metal
parts touching the welding wire are electrically live. Incorrectly
installed or improperly grounded equipment is a hazard.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from work and ground using dry insulating mats or covers.
4. Disconnect input power or stop engine before installing or servicing this equip-
ment. Lock input power disconnect switch open, or remove line fuses so power
cannot be turned on accidentally.
5. Properly install and ground this equipment according to its Owner’s Manual
and national, state, and local codes.
6. Turn off all equipment when not in use. Disconnect power to equipment if it
will be left unattended or out of service.
7. Use fully insulated electrode holders. Never dip holder in water to cool it or lay
it down on the ground or the work surface. Do not touch holders connected to
two welding machines at the same time or touch other people with the holder
or electrode.
8. Do not use worn, damaged, undersized, or poorly spliced cables.
9. Do not wrap cables around your body.
10. Ground the workpiece to a good electrical (earth) ground.
11. Do not touch electrode while in contact with the work (ground) circuit.
12. Use only well-maintained equipment. Repair or replace damaged parts at once.
13. In confined spaces or damp locations, do not use a welder with AC output
unless it is equipped with a voltage reducer. Use equipment with DC output.
14. Wear a safety harness to prevent falling if working above floor level.
15. Keep all panels and covers securely in place.
ARC RAYS can burn eyes and skin;
NOISE can damage hearing.
Arc rays from the welding process produce intense heat and strong
ultraviolet rays that can burn eyes and skin. Noise from some
processes can damage hearing.
1. Use a Welding Helmet or Welding Faceshield fitted with a proper shade of filter
(see ANSI Z49.1 and AS 1674 listed in Safety Standards) to protect your face
and eyes when welding or watching.
2. Wear approved safety glasses. Side shields recommended.
3. Use protective screens or barriers to protect others from flash and glare; warn
others not to watch the arc.
4. Wear protective clothing made from durable, flame-resistant material (wool
and leather) and foot protection.
5. Use approved ear plugs or ear muffs if noise level is high.
FUMES AND GASES can be hazardous
to your health.
Welding produces fumes and gases. Breathing these fumes and
gases can be hazardous to your health.
1. Keep your head out of the fumes. Do not breathe the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to remove welding
fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDS) and the manufacturer’s instruction
for metals, consumables, coatings, and cleaners.
5. Work in a confined space only if it is well ventilated, or while wearing an air-
supplied respirator. Shielding gases used for welding can displace air causing
injury or death. Be sure the breathing air is safe.
6. Do not weld in locations near degreasing, cleaning, or spraying operations.
The heat and rays of the arc can react with vapours to form highly toxic and
irritating gases.
7. Do not weld on coated metals, such as galvanised lead, or cadmium plated steel,
unless the coating is re moved from the weld area, the area is well ventilated,
and if necessary, while wearing an air supplied respirator. The coatings and
any metals containing these elements can give off toxic fumes if welded.
