8. Connecttheworklead/clamptothejobasclose
to the welding area as practical to prevent weld-
ing current from travelling long, possibly un-
known paths and causing electric shock and re
hazards.
9. Do not use a welder to thaw frozen pipes.
10.Removethe stick electrodefrom the holder or
cut o the welding wire at the contact tip when
not in use.
Sparks & Hot Metal
WARNING!
Chipping and grinding causes ying metal, and
as welds cool they can throw o slag.
1. WearanAS/NZSapprovedfaceshieldorsafety
goggles.Sideshieldsarerecommended.
2. Wear appropriate safety equipment to protect
the skin and body.
Cylinders
WARNING!
Gas cylinders contain gas under high pressure. If
damaged, a cylinder can explode. Since gas cyl-
inders are normally part of the welding
process, be sure to treat them carefully.
1. Protect compressed gas cylinders from excessive
heat, mechanical shocks, and arcs.
2. Install and secure cylinders in an upright posi-
tion by chaining them to a stationary support or
equipment cylinder rack to prevent falling or tip-
ping.
3. Keep cylinders away from any welding or other
electrical circuits.
4. Never allow a welding electrode to touch any
cylinder.
5. Useappropriateshieldinggas,regulators,hoses,
and ttings designed for the specic application;
maintain them and their associated parts in
good condition.
6. Turn your face away from the valve outlet when
opening the cylinder valve.
3. If ventilation is poor, use an approved air-sup-
plied respirator.
4. ReadtheSafetyDataSheets(SDS)andtheman-
ufacturer’s instruction for the metals, consuma-
bles, coatings, and cleaners.
5. Workinaconnedspaceonlyifitiswellventi-
lated, or while wearing an air-supplied respirator.

is safe.
6. Do not weld in locations near degreasing, clean-
ing, 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 galva-
nized, lead, or cadmium plated steel, unless the
coating is removed 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 o
toxic fumes if welded.
Fire & Explosive Risks
WARNING!
Sparks and spatter y o from the welding arc.
The ying sparks and hot metal, weld spatter,
work piece, and hot equipment can cause res
and burns.
Accidental contact of electrode or welding wire to
metal objects can cause sparks, overheating, or re.
1. Protect yourself and others from ying sparks
and hot metal.
2. Do not weld where ying sparks can strike am-
mable material.
3. Removeallammableswithin10moftheweld-
ing site.
4. Be alert that welding sparks and hot materials
from welding can easily go through small cracks
and openings to adjacent areas.
5. Watchforre,andkeepareextinguishernear-
by.
6. Be awarethat weldingona ceiling, oor,bulk-
head, or partition can cause re on the hidden
side.
7. Do not weld on closed containers such as tanks
or drums.
