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 ow 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 ow 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 ttings 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.
Esseti NZ Ltd, authorised representatives or agents of Esseti NZ Ltd will not be liable
or responsible for the loss of any gas.
ATTENTION! - CHECK FOR GAS LEAKS

SAFETY
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 under-
stand this instruction manual carefully before the installation and operation of this equipment.
• 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 qualied.
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 circuit, electrodes and wires with bare hands.
The operator must wear dry welding gloves while he/she performs the welding 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.
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 fumes and
gases. Use of a PAPR system is recommended.
• In conned or heavy fume environments always wear an approved air-supplied respirator.
Welding 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 in locations near de-greasing, 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. Do not weld these materials unless the area is very well ventilated, and or wearing
an air supplied respirator.
Arc rays: harmful to people’s eyes and skin. Arc rays from the welding 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 lter lens and suitable protective clothing including
welding gloves whilst the welding 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 ash,glare and sparks; warn others not to watch the arc.
Machine Operating Safety

Fire hazard. Welding on closed containers, such as tanks,drums, or pipes, can cause them
to explode. Flying sparks from the welding arc, hot work piece, and hot equipment can cause
res and burns. Accidental contact of electrode to metal objects can cause sparks, explosion,
overheating, or re. Check and be sure the area is safe before doing any welding.
• The welding sparks may cause re, therefore remove any ammable materials away from the working
area, at least 12m from the welding arc. Cover ammable materials and containers with approved covers
if unable to be moved from the welding area.
• Do not weld on closed containers such as tanks, drums, or pipes, unless they are properly prepared
according to the required Safety Standards to insure that ammable or toxic vapors 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 where the atmosphere may contain ammable dust, gas, or liquid vapours (such as petrol)
• Have a re extinguisher nearby and know how to use it. Be alert that welding sparks and hot materials
from welding can easily go through small cracks and openings to adjacent areas. Be aware that welding
on a ceiling, oor, bulkhead, or partition can cause re on the hidden side.
Gas Cylinders. Shielding gas cylinders contain gas under high pressure. If damaged, a cylin-
der can explode. Because gas cylinders are normally part of the welding process, be sure to
treat them carefully. CYLINDERS can explode if damaged.
• Protect gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open ames,
sparks, and arcs.
• Ensure cylinders are held secure and upright to prevent tipping or falling over.
• Never allow the welding electrode or earth clamp to touch the gas cylinder, do not drape welding cables
over the cylinder.
• Never weld 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 are invisible and odourless.
• Shut off shielding gas supply when not in use.
• Always ventilate conned spaces or use approved air-supplied respirator.
Electronic magnetic elds. 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 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
gun. Use insulated welding gloves and clothing to handle hot parts and prevent burns.

TIG welding can be combined with the high penetration of DC TIG welding, obtaining higher
welding speeds and establishing the weld puddle quicker on cold workpieces. The operator
adjustable parameter is the percentage of AC waveform compared to DC- waveform over the
entire period, which can be varied from 5~95%. Ideal for welding heavier gauge material with
less current than AC welding.
AC Square Wave: Allows the current to change from electrode + positive to electrode - nega-
tive very quickly. This produces high voltage as the current switches polarities allowing the
arc to restart 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
effect 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 tran-
sitions to eliminate the need for continuous HF.
