The input power circuit and machine internal 

circuits are also live when power is on. In semi-

automatic 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.

 

DANGER!

 

Touching live electrical parts can cause fatal  

 

shocks or severe burns. The electrode and work  

 

circuit is electrically live whenever the output is  

 on.

 

CAUTION!

 

Noise from some processes can damage 

 

 

hearing. Use AS/NZS compliant ear plugs or ear  

 

muffs if the noise level is high.

 

DANGER!

 

Remove any combustible material from the 

 

 work area.

Electricity Can Kill

Noise Can Damage Hearing

Work Environment Safety

1.  When possible, move the work to a location well 

away from combustible materials. If relocation 

is not possible, protect the combustibles with 

a cover made of fire resistant material.

2.  Remove or make safe all combustible materials 

for a radius of 10 metres around the work area. 

Use a fire resistant material to cover or block 

all doorways, windows, cracks, and other 

openings.

3.  Enclose the work area with portable fire 

resistant screens. Protect combustible walls, 

ceilings, floors, etc., from sparks and heat with 

fire resistant covers.

4.  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 

welding process and well after the welding is 

completed.

5.  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.

6.  After welding, make a thorough examination 

for evidence of fire. Be aware that visible 

smoke or flame may not be present for some 

time after the fire has started. Do not weld or 

cut in atmospheres containing dangerously 

reactive or flammable gases, vapours, liquids, 

and dust. Provide adequate ventilation in work 

areas to prevent accumulation of flammable 

gases, vapours, and dust.

1.  Do not touch live electrical parts.
2.  Wear dry, hole-free insulating gloves and body 

protection.

3.  Insulate yourself from the work and the 

ground using dry insulating mats or covers.

4.  Disconnect input power before installing or 

servicing this equipment. 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 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 

the 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.  Connect work piece to a good electrical 

ground.

7.  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 vapours. 

Clean and purge containers before applying 

heat. Vent closed containers, including 

castings, before preheating, welding, or 

cutting.

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 safety protection.

5.  Never wear contact lenses while welding.
