Premium features include:-

1. Inverter power source – more efficient to operate, provides smoother weld characteristics.

2. Pulse welding in DC Tig welding mode

3. HF Arc start – Easy arc striking and prolonged tungsten life

4. Slope up / slope down

5. Digital amp meter

6. Industrial 35% Duty cycle at 160 Amps @ 40C

Recommended Processes

The R-Tech Tig160PDC is recommended for the Tig welding processes within its output capacity of

160 Amps

Equipment Limitations

The R-Tech Tig160PDC is protected from overloads beyond the output ratings and duty cycle as

per machine specifications with thermostat protection of the output coils and rectifiers.

Welding Capability – Duty Cycle

The R-Tech Tig160PDC is rated at 160 Amps at 35% duty cycle on a ten minute basis. If the duty

cycle is exceeded a thermal protector will shut machine off until the machine cools.

Safety Precautions

Read entire section before starting installation

WARNING!

Electric Shock can kill – Only qualified personnel should perform this installation. Turn off 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 national recommended standards.

Select suitable location

Place the welder where clean cooling air can freely circulate in and out of the front & rear louver

vents. Dirt, dust or any foreign material that can be drawn through vents into welder must be kept to

a minimum. Failure to observe these precautions can result in excessive operating temperatures

which can lead to plant failure.

Grinding

Do not direct grinding particles towards the welder. An abundance of conductive material can cause

plant failure.

Stacking

This machine cannot be stacked.

Transport – Unloading

Never underestimate the weight of equipment, never move or leave suspended in the air above

people. Use recommended lifting equipment at all times.

WARNING!

Falling Equipment can cause injury. Never lift welder with gas bottle attached. Never lift above

personnel.

Tilting

Machine must be placed on a secure level surface or on a recommended undercarriage/trolley.

This machine may topple over if this procedure is not followed.

Environmental Rating

The welding power source carries the IP21S rating. It may be used in normal industrial and

commercial environments. Avoid using in areas where water / rain is around.

Read and follow the ‘Electric Shock Warnings’ in the safety section if welding must be performed

under electrically hazardous conditions such as welding in wet areas or water on the work piece.

Electrical Installation

WARNING!

ELECTRIC SHOCK CAN KILL

Machine grounding and High Frequency Interference Protection

This welder must be grounded to earth. See national electrical codes fro proper grounding

methods.

The high frequency generator being similar to a radio transmitter 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-radiation by un-grounded metallic objects.

Keeping these contributing factors in mind, installing equipment as per following instructions should

minimize problems.

1. Keep the welder input power lines as short as possible and enclose as much of them as

possible in metal 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

practical.

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 connection to work in good condition – Clean area on workbench where

earth clamp is situated on a regular basis.

Input Connections

Make sure the voltage, phase and frequency of input power is as specified on machine rating plate

located at rear of machine.

Have a qualified electrician provide suitable input power as per national electrical codes. Make sure

machine is earthed / grounded.

Make sure fuse or circuit breaker is correct rating for machine. Using fuses or circuit breakers

smaller than recommended will result in ‘nuisance’ shut off from welder inrush currents even if

welding at low amperages.

Failure to follow these instructions can cause immediate failure within the welder and void

machines warranty.

Turn the input power OFF at the mains switch & fuse box before working on this equipment.

Have a qualified 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 TIG160PDC Inverter Tig Welder requires a 240V 50/60Hz 13amp fused supply. It comes with a

2 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 – 5 KVA 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 warranty.

To avoid a High Frequency shock keep the Tig torch in good condition and replace if any of the

insulation is damaged.

Connect the gas input hose to gas regulator and use ‘Pure Argon’ Gas, available from local

suppliers. Set gas flow/pressure to 8-12 LPM.

Make sure gas bottle is secured to avoid injury.
