Welding and cutting equipment can be dangerous to both the operator and people in or near the

surrounding working area if the equipment is not correctly operated. Equipment must only be used

under the strict and comprehensive observance of all relevant safety regulations.

Read and understand this instruction manual carefully before the installation and operation of this equipment.

Machine Operating Safety

• Do not switch the function modes while the machine is operating. Switching of the function modes during

welding can damage the machine. Damage caused in this manner will not be covered under warranty.

• Disconnect the electrode-holder cable from the machine before switching on the machine, to avoid arcing

should the electrode be in contact with the workpiece.

• Operators should be trained and or qualiﬁed.

Arc rays: harmful to people’s eyes and skin. Arc rays from the welding/cutting process produce intense visible

and invisible ultraviolet and infrared rays that can burn eyes and skin.

• Always wear a welding helmet with the correct shade of ﬁlter lens and suitable protective clothing, including

welding gloves while the welding/cutting operation is performed.

• Measures should be taken to protect people in or near the surrounding working area. Use protective screens or

barriers to protect others from ﬂash, glare and sparks; warn others not to watch the arc.

Fumes and gases are dangerous. Smoke and gas generated while welding or cutting can be harmful to people’s

health. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.

• Do not breathe the smoke and gas generated while welding or cutting, keep your head out of the fumes.

• Keep the working area well ventilated, use fume extraction or ventilation to remove welding/cutting fumes and

gases.

• In conﬁned or heavy fume environments always wear an approved air-supplied respirator.

• Welding/cutting fumes and gases can displace air and lower the oxygen level, causing injury or death. Be sure

the breathing air is safe.

• Do not weld/cut 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.

• Materials such as galvanised, lead, or cadmium plated steel, containing elements that can give o toxic fumes

when welded/cut. Do not weld/cut these materials unless the area is very well ventilated, and or wearing an

air-supplied respirator.

Electric shock: It 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 internal machine circuits

are also live when power is on. In MIG/MAG welding, the wire, drive rollers, wire feed housing, and all metal

parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is

dangerous.

• Connect the primary input cable, according to Australian and New Zealand standards and regulations.

• Avoid all contact with live electrical parts of the welding/cutting circuit, electrodes and wires with bare hands.

• The operator must wear dry welding gloves while he/she performs the welding/cutting task.

• The operator should keep the workpiece insulated from himself/herself.

• Keep cords dry, free of oil and grease, and protected from hot metal and sparks.

• Frequently inspect input power cable for wear and tear, replace the cable immediately if damaged, bare wiring

is dangerous and can kill.

• Do not use damaged, undersized, or badly joined cables.

• Do not weld in the rain.

• Do not drape cables over your body.

• We recommend (RCD) safety switch is used with this equipment to detect any leakage of current to earth.

SAFETY

General Information

Fire hazard. Welding/cutting on closed containers, such as tanks, drums, or pipes, can cause them to explode.

Flying sparks from the welding/cutting arc, hot workpiece, and hot equipment can cause ﬁres and burns.

Accidental contact of the electrode to metal objects can cause sparks, explosion, overheating, or ﬁre. Check and

be sure the area is safe before doing any welding/cutting.

• The welding/cutting sparks & spatter may cause ﬁre, therefore remove any ﬂammable materials well away from

the working area. Cover ﬂammable materials and containers with approved covers if unable to be moved from

the welding/cutting area.

• Do not weld/cut on closed containers such as tanks, drums, or pipes, unless they are correctly prepared

according to the required Safety Standards to ensure that ﬂammable or toxic vapours and substances are totally

removed, these can cause an explosion even though the vessel has been "cleaned". Vent hollow castings or

containers before heating, cutting or welding. They may explode.

• Do not weld/cut where the atmosphere may contain ﬂammable dust, gas, or liquid vapours (such as petrol)

• Have a ﬁre extinguisher nearby and know how to use it. Be alert that welding/cutting sparks and hot materials

from welding/cutting can easily go through small cracks and openings to adjacent areas. Be aware that welding/

cutting on a ceiling, ﬂoor, bulkhead, or partition can cause a ﬁre on the hidden side.

Gas Cylinders. Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode.

Because gas cylinders usually are part of the welding/cutting process, be sure to treat them carefully. CYLINDERS

can explode if damaged.

• Protect gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open ﬂames, sparks, and arcs.

• Ensure cylinders are held secure and upright to prevent tipping or falling over.

• Never allow the welding/cutting electrode or earth clamp to touch the gas cylinder, do not drape welding cables

over the cylinder.

• Never weld/cut on a pressurised gas cylinder, it will explode and kill you.

• Open the cylinder valve slowly and turn your face away from the cylinder outlet valve and gas regulator.

Gas build-up. The build-up of gas can cause a toxic environment, deplete the oxygen content in the air resulting

in death or injury. Many gases use in welding/cutting are invisible and odourless.

• Shut o shielding gas supply when not in use.

• Always ventilate conﬁned spaces or use approved air-supplied respirator.

Electronic magnetic ﬁelds. MAGNETIC FIELDS can aect Implanted Medical Devices.

• Wearers of Pacemakers and other Implanted Medical Devices should keep away.

• Implanted Medical Device wearers should consult their doctor and the device manufacturer before going near

any electric welding, cutting or heating operation.

Noise can damage hearing. Noise from some processes or equipment can damage hearing.

• Wear approved ear protection if noise level is high.

Hot parts. Items being welded/cut generate and hold high heat and can cause severe burns.

• Do not touch hot parts with bare hands. Allow a cooling period before working on the welding/cutting gun. Use

insulated welding gloves and clothing to handle hot parts and prevent burns.

ATTENTION! - CHECK FOR GAS LEAKAGE

At initial set up and at regular intervals we recommend to check for gas leakage

Recommended procedure is as follows:

1. Connect the regulator and gas hose assembly and tighten all connectors and clamps.

2. Slowly open the cylinder valve.

3. Set the ﬂow rate on the regulator to approximately 8-10 L/min.

4. Close the cylinder valve and pay attention to the needle indicator of the contents pressure gauge on the

regulator, if the needle drops away towards zero there is a gas leak. Sometimes a gas leak can be slow

and to identify it will require leaving the gas pressure in the regulator and line for an extended time period.

In this situation it is recommended to open the cylinder valve, set the ﬂow rate to 8-10 L/min, close the

cylinder valve and check after a minimum of 15 minutes.

5. If there is a gas loss then check all connectors and clamps for leakage by brushing or spraying with soapy

water, bubbles will appear at the leakage point.

6. Tighten clamps or ﬁttings to eliminate gas leakage.

IMPORTANT! - We strongly recommend that you check for gas leakage prior to operation of your

machine. We recommend that you close the cylinder valve when the machine is not in use.

Welding Guns Of Australia PTY LTD, authorised representatives or agents of Welding Guns Of Australia

PTY LTD will not be liable or responsible for the loss of any gas.
