5. TIG WELDING
IWT-130U
Starting Arc
1. Hold electrode above work piece at weld start point and enable
output of inert gas.
2. Touch electrode to work piece for 1-2 seconds.
3. Slowly lift electrode, arc is formed when electrode is lifted
4. Tilt torch and travel at a consistent speed
Touch
1-2 Seconds
CAUTION!:
Ensure approved welding helmet/mask is
worn at all times to protect your face and eyes from
arc rays and sparks.

IMPORTANT!:
Check for gas leakage prior to
operation of your inverter welder. Close the cylinder
valve when the inverter welder is not in use.
2. Attach TIG Torch lead
to the NEGATIVE (-)
output terminal. Insert &
rotate until connection is
firm.

3. Attach Earth Clamp lead
to the POSITIVE (+)
output terminal. Insert &
rotate until connection is
firm.
5. Attach the Earth Clamp to
the work piece ensuring
area is free from paint or
dirt so that there is a good
electrical connection.
1. Set Process Selection
Switch to TIG WELDING
process.
4. Set up the gas hose and
pressure regulator.
WARNING!:
ENSURE THE TOOL IS DISCONNECTED
FROM THE POWER SUPPLY BEFORE PERFORMING
ANY OF THE FOLLOWING OPERATIONS.
Before starting you will require a suitable Regulator and bottle of
Inert Gas.

6. Connect the Inverter welder power cord into a power outlet.
Different Types of Electrodes
Tungsten electrodes are colour coded at the end for easy
identification.
A couple of the most commonly used tungsten electrodes available
in Australia and New Zealand are listed below.
Tungsten Type:
2% Cerium Tungsten (Grey tipped).
This tungsten requires less amperage to start so it is recommended
for thinner metals, it can be used to weld every type of metal.
2% Thoriated Tungsten (Red tipped).
They are most commonly used electrodes and are preferred for their
longevity and ease of use. Best stability is achieved at medium cur-
rents, good arc starts. Commonly used for steel and stainless steel
applications.
Note:
Avoid use of long extension leads .
