SAFETY INFORMATION

The following types of welding operation
must be performed by a qualified coded
welder and approved by a qualified welding
inspector.

The welding of pressure vessels for liquid
and gaseous substances.

The welding of pressurised pipe work for
liquid and gaseous substances.

The repair of containers for flammable liquids
and corrosive chemicals.

Structural support and load bearing
steelwork in buildings.

Load lifting and moving equipment.

Load lifting slings, chains, hooks and
shackles.

Hydraulic systems.

Any type of safety critical equipment.

In addition to the above it is strongly
recommended that the following welding
operations are checked by a competent person.

The repair of vehicle chassis and suspension
and steering components.

Vehicle load bearing attachment points ie,
engine mounts seat and seat belt anchor
points.

Motor Cycle frames and components.

General Safety Rules
Warning!

Read all instructions Failure to follow

all instructions listed below may result in electric
shock, fire and/or serious injury. The term
"power tool" in all of the warnings listed below
refers to your mains operated welder.

Save These Instructions

1) Work Area

a)

Keep work area clean and well lit.

Cluttered and dark areas invite accidents.

b)

Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust.

Power

tools create sparks which may ignite the dust
or fumes.

c)

Keep children and bystanders away while
operating a power tool.

Distractions can

cause you to lose control.

2) Electrical Safety

a)

Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools.

Unmodified plugs

and matching outlets will reduce risk of
electric shock.

b)

Avoid body contact with earthed or
grounded surfaces such as pipes,
radiators, ranges and refrigerators.

There is an increased risk of electric shock if
your body is earthed or grounded.

c)

Do not expose power tools to rain or wet
conditions.

Water entering a power tool will

increase the risk of electric shock.

d)

Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil,
sharp edges or moving parts.

Damaged or

entangled cords increase the risk of electric
shock.

e)

When operating a power tool outdoors,
use an extension cord suitable for outdoor
use.

Use of a cord suitable for outdoor use

reduces the risk of electric shock.

3) Personal Safety

a)

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

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

b)

Use safety equipment. Always wear eye
protection.

Safety equipment such as dust

mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate
conditions will reduce personal injuries.
