Health hazard information
The actual process of welding is one that can cause a variety of hazards.
All appropriate safety equipment should be worn at all times, i.e.
headwear, hand and body protection. Electrical equipment should be
used in accordance with the manufacturer’s recommendations.
Eyes
The process produces ultra violet rays that can injure and cause
permanent damage. Fumes can cause irritation.
Skin
Arc rays are dangerous to uncovered skin.
Inhalation
Welding fumes and gases are dangerous to the health of the operator
and to those in close proximity. The aggravation of pre-existing
respiratory or allergic conditions may occur in some workers. Excessive
exposure may cause conditions such as nausea, dizziness, dryness and
irritation of eyes, nose and throat.
Personal protection
Respiratory
Conned space welding should be carried out with the aid of a fume
respirator or air supplied respirator as per AS/NZS 1715 and AS/NZS
1716 Standards.
→You must always have enough ventilation in conned spaces. Be alert
to this at all times.
→Keep your head out of the fumes rising from the arc.
→Fumes from the welding of some metals could have an adverse e󹟽ect
on your health. Don’t breathe them in. If you are welding on material
such as stainless steel, nickel, nickel alloys or galvanised steel,
further precautions are necessary.
→Wear a respirator when natural or forced ventilation is insu󹟾cient.
Eyes
A welding helmet with the appropriate welding lter lens for the
operation must be worn at all times in the work environment. The
welding arc and the reecting arc ash gives out ultraviolet and infrared
rays. Protective welding screen and goggles should be provided for
others working in the same area.
Recommended lter shades for arc welding
Less than 150 amps Shade 10*
150 to 250 amps Shade 11*
250 to 300 amps Shade 12
300 to 350 amps Shade 13
Over 350 amps Shade 14
*Use one shade darker for aluminium.
Clothing
Suitable clothing must be worn to prevent excessive exposure to UV
radiation and sparks. An adjustable helmet, ameproof loose-tting
cotton clothing buttoned to the neck, protective leather gloves, spats,
apron and steel capped safety boots are highly recommended.

Cylinder safety
→Read labels and Safety Data Sheet (SDS) before use
→Store upright and use in well ventilated, secure areas away from
pedestrian or vehicle thoroughfare
→Guard cylinders against being knocked violently or being allowed to
fall
→Wear safety shoes, glasses and gloves when handling and connecting
cylinders
→Always move cylinders securely with an appropriate trolley. Take care
not to turn the valve on when moving a cylinder
→Keep in a cool, well ventilated area, away from heat sources, sources
of ignition and combustible materials, especially ammable gases
→Keep full and empty cylinders separate
→Keep ammonia-based leak detection solutions, oil and grease away
from cylinders and valves
→Never use force when opening or closing valves
→Don’t repaint or disguise markings and damage. If damaged, return
cylinders to BOC immediately
Cylinder valve safety
When working with cylinders or operating cylinder valves, ensure
that you wear appropriate protective clothing – gloves, boots and
safetyglasses. When moving cylinders, ensure that the valve is not
accidentally opened in transit.
Before operating a cylinder valve
Ensure that the system you are connecting the cylinder into is suitable
for the gas and pressureinvolved.
Ensure that any accessories (such as hoses attached to the cylinder
valve, or the system being connected to) are securely connected. Ahose,
for example, can potentially ail around dangerously if it is accidentally
pressurised when not restrained at both ends.
Stand to the side of the cylinder so that neither you nor anyone else is
in line with the back of the cylinder valve. This is in case a back-plug
is loose or a bursting disc vents. The correct stance is shown in the
diagramabove.
When operating the cylinder valve
Open it by hand by turning the valve hand-wheel anti-clockwise. Use
only reasonable force.
Ensure that no gas is leaking from the cylinder valve connection or
the system to which the cylinder is connected. DO NOT use ammonia-
based leak detection uid as this can damage the valve. Approved leak
detection uid, can be obtained from a BOC Gas & Gear centre.
When nished with the cylinder, close the cylinder valve by hand
by turning the valve hand-wheel in a clockwise direction. Use only
reasonable force.
Remember NEVER tamper with the valve.
If you suspect the valve is damaged, DONOT use it. Report the issue to
BOC and arrange for the cylinder to be returned to BOC.

How important is the correct
input cable and plug on
a welding machine?
The size of the plug depends on a formula that
not only uses the maximum current draw but
also the duty cycle of the power source. Theuse
of any welding power source will not only cause
the machine itself to heat up, but the input cable,
plug and mains power circuit will increase in
temperature as well. That’s why it’s important
to understand input and output currents and to
make sure that the input circuit is correctly rated
to supply the required input draw. Thisallows the
machine to operate at or near maximum output
and protects the circuit board from tripping,
overheating and/or catchingre.
For your safety, BOC meets
AS/NZS Standards for safe
electricalcompliance
Regulatory Compliance Mark (RCM)
andnumber
All BOC welding machines undergo an
independent certication process to meet
Australian and New Zealand regulations
regarding electrical safety. The triangle-circle-
tick (RCM) symbol signies that BOC has taken
the necessary steps to have the product comply
with the electrical safety and/or electromagnetic
compatibility (EMC) legislative requirements as
specied by the Electrical Regulatory Authorities
Council (ERAC). Depending on the machine, BOC
may be required to have a 32A single phase
plug to ensure that when the machine runs at
its maximum output, the input supply plug and
lead will not overheat. For your safety, please
check for this symbol before buying any welding
machine in Australia and NewZealand.
Check the rating plate
onyourmachine
All welding machines that comply with IEC 60974
or AS 60974 must have a rating plate similar to
the one shown. Welding machines draw some
current when idle (not welding) and a higher
current when welding. E󹟽ective rated primary
current (I1e󹟽 ) combines the conductor heating
due to these two levels of current. I1e󹟽 is the
maximum rated e󹟽ective supply current that
determines the minimum plug and input cable
rating as well as the minimum capacity of the
input circuit that the machine gets plugged
into to safely operate the machine. Look for
the I1e󹟽 (see lower right in our example) on the
welding machine’s rating plate and ensure that
you have the correct input circuit to support this
powerdraw.
What if I don’t have a 240 volt
15 amp or 32 ampoutlet?
If you don’t have a suitable power outlet, you
should contact a qualied electrician to advise
whether the wiring in your building will cater for
a 15 amp or 32 amp outlet. You mayalso need
to upgrade your circuit breakers and possibly
switchboard to suit. Failure to do this may cause
an electrical re in the building which may
voidinsurances.
✓ Use the correct input current,
✓cable and ✓ plug in accordance
with AS60974-1 for your safety and
to get the maximum performance
from your welding machine.
Example
If the I1e󹠋 rating on your
machine is 27A then you must
use a 32A plug as a 15A is
undersized for the welding
current being used and may
cause the cable to overheat.
✖ Risk damage to your machine
or cause tripping and/or re by
using the wrong input current,
cable orplug.
✖ Tamper with plugs or
ledown earth pins. Doing so
willvoidwarranty.
✓ Inspect cables and plugs regularly.
✓ Contact a qualied electrician
for advice and/or upgrade and, if
needed, to replace any damaged
plugs orcables.
