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 work piece.
• Operators should be trained and or qualified.
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 work piece 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, under sized, or badly joined cables.
• 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.
Fumes and gases are dangerous. Smoke and gas generated whilst 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 whilst 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 galvanized, lead, or cadmium plated steel, containing elements that
can give off 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.

TIG200L PRO AC/DC

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 correct
shade of filter lens and suitable protective clothing including welding gloves whilst 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.
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 work piece, and hot equipment can cause fires and burns.
Accidental contact of 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
properly prepared according to the required Safety Standards to insure 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 fire on the hidden side.
Gas Cylinders. Shielding gas cylinders contain gas under high pressure. If damaged, a
cylinder can explode. Because gas cylinders are normally 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.
• Insure 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 causes 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 off shielding gas supply when not in use.
• Always ventilate confined spaces or use approved air-supplied respirator.

Electronic magnetic fields. MAGNETIC FIELDS can affect 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.
