Safety Precauons
Read enre secon before starng installaon.
Warning!
Electric Shock can kill – Only qualied personnel should perform this installaon. Turn o input power at
the fuse box before working on this equipment. Do not touch electrically live parts. Always connect the
machine to an earthed mains supply as per naonal recommended standards.
Select suitable locaon
Place the welder where clean cooling air can freely circulate in and out of the front & rear louvre vents.
Dirt, dust or any foreign material that can be drawn through vents into welder must be kept to a mini-
mum. Failure to observe these precauons can result in excessive operang temperatures which can lead
to plant failure.
Grinding
Do not direct grinding parcles towards the welder.
An abundance of conducve material can cause plant failure.
Transport & unloading
Never underesmate the weight of equipment, never move or leave suspended in the air above people.
Use recommended liing/handling equipment at all mes.

Electrical installaon
WARNING ELECTRIC SHOCK CAN KILL
Electric Shock can kill – Only qualied personnel should perform this installaon. Turn o input power at
the fuse box before working on this equipment. Do not touch electrically live parts. Always connect the
machine to an earthed mains supply as per naonal recommended standards.
Machine grounding and High Frequency Interference Protecon
This welder must be grounded to earth. See naonal electrical codes for proper grounding methods.
The high frequency generator being similar to a radio transmier may cause interference to radio, TV and
other electronic equipment. These problems may be the result of radiated interference.
Proper grounding methods can reduce or eliminate this.
Radiated interference can develop in the following ways
1. Direct interference from welder power source
2. Direct interference from the welding leads
3. Direct interference radiated from feedback into power lines
4. Interference from re-radiaon by un-grounded metallic objects.
Keeping these contribung factors in mind, installing equipment as per following instrucons should
minimize problems.
1. Keep the welder input power lines as short as possible and enclose as much of them as possible in met-
al conduit or equivalent shielding. There should be a good electrical contact between this conduit and
ground (Earth).
2. Keep the work and electrode leads as short as possible. Tape the leads together where praccal.
3. Be sure the torch and earth leads rubber coverings are free from cuts and cracks that allow welding
power leakage
4. Keep earth lead connecon to work in good condion – Clean area on workbench where earth clamp is
situated on a regular basis.

Electrical installaon cont.
Input Connecons
Make sure the voltage, phase and frequency of input power is as specied on machine rang
plate located at rear of machine.
Have a qualied electrician provide suitable input power as per naonal electrical codes. Make
sure machine is earthed / grounded.
Make sure fuse or circuit breaker is correct rang for machine. Using fuses or circuit breakers
smaller than recommended will result in ‘nuisance’ shut o from welder inrush currents even if
welding at low amperages.
Failure to follow these instrucons can cause immediate failure within the welder and void ma-
chines warranty.
Turn the input power OFF at the mains switch & fuse box before working on this equipment. Have
a qualied electrician install & service this equipment.
Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before
working inside this equipment. Do not touch electrically live parts
The TIG171-TFT DIGITAL Inverter Tig Welder requires a 240V 50/60Hz supply. It requires a 16A
supply. It comes with a 2.5 metre mains cable attached.
Connect wires according to national coding.
Brown wire – Live
Blue wire – Neutral
Green/Yellow Wire – Earth (Ground)
Connecting to an Engine Driven Generator
If connecting this machine to an engine driven generator please ensure the following
Minimum Generator KVA Output – 6KVA continuous Generator to be fitted with AVR
(automatic voltage regulation) DO NOT USE ON A GENERATOR WITHOUT AVR
Connecting to a generator without the above minimum requirements will in- validate your war-
ranty.
