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 weld in the rain.
• Do not use damaged, undersized, 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.
SAFETY

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 aect 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.

Water Cooler Mode
Provides electronic link when water cooler unit is connected to the machine
• Press button to turn ON / OFF
GAS TEST
Press the GAS TEST button to initiate a gas test. After 20s the test will end, you
can also end the test by pressing the GAS TEST button again.
Water Cooler Connection
The water cooler is connected to the power source via a 5 Pin connector located
at the rear of the machine. The connector provides 220-230VAC power supply
to the water cooler unit via Pins 1&2. The machine will monitor the water flow and
welding o time via a signal circuit connected to Pins 3&4.
NOTE: This sensor circuit will turn o the welding output should there be no
or insucent water flow from the water cooler unit. This will prevent the Water
Cooled torch cable from over heating and burning out.
When using RAZOR 320 AC/DC machine with a Water Cooled TIG Torch ensure:
1. The water cooler is plugged into the power supply at the rear of the Power Source.
2. The water level is to the full level.
3. The water cooler is switched on using the on/o switch located on the front
panel of the water cooler.
4. The power source is in Water Cooler Mode by selecting the Water On icon on
the front panel.

Razor32OAC/DC TIG-MMA
AC Square Wave: Allows the current to change from electrode + positive to electrode - negative
very quickly. This produces high voltage as the current switches polarities allowing the arc to re-
start easily. The arc can be maintained without the use of high-frequency and the fast transitions
provide for responsive, dynamic and focused arc for better directional control.
AC Triangle Wave: Characterised by a particularly soft and concentrated arc combining the ef-
fect of peak amperage while reducing overall heat input. Leads to quick puddle formation and,
because of lowered heat input, reduced weld distortion, especially on thin material This wave
form is ideal for very precise welding of thin Aluminum plate.
AC Sine Wave: It is the standard Wave form, characterised by low noise and excellent arc
control, it also gives the soft-arc feel of a conventional power source, while using square transi-
tions to eliminate the need for continuous HF.

Increasing Square Wave Frequency
It is possible with the RAZOR320ACDC machine to adjust the frequency of the AC Square Wave output. It means that the
amount of time that it takes the AC square wave to complete a full cycle switch from postive (+) to negative (-) can be ad-
justed from 20Hz (20 times per second) to 200Hz
Increasing frequency (Hz) causes the current to change direction more often, which means that it spends less time per cycle
in both DC electrode negative and DC electrode positive mode. By spending less time at each polarity, the arc cone has less
time to expand.
A higher frequency produces a narrower arc cone producing an arc that is tighter with more focus at the exact spot the
electrode is pointing. The result is improved arc stability, ideal for llet welds and other t ups requiring precise penetration.
Decreasing the frequency softens the arc and broadens the weld pool producing a wider bead, produces good overall pen-
etration and ideal for build up applications.
