4.0 Connections
4.1
Power
The machine is designed to operate on a 240V
±15% input single phase AC outlet. The machine
is supplied with a heavy duty 10A input plug.
Ensure that there is adequate ventilation around
the machine when it is connected to the mains
power supply.
4.2 Shielding gas
When working in TIG mode this welding process
requires shielding gas. The shielding gas can be
supplied via a regulator to the machine from either
a fixed installation or single cylinder of gas.
If a cylinder of gas is used, please ensure that the
cylinder is securely fastened (refer to the section
on cylinder handling and safety), before starting
any welding operation.
4.3 TIG torch connection
The Raptor 180 TIG ACDC machine is rated at 180A
at 10% duty cycle.
The TIG torch is fitted to the machine by means
of the Safe Lock dinse back end. For DC (-) TIG
operation, fit the torch back end to the negative
dinse connection. Similarly for DC (+), fit the torch
back end to the positive dinse connection.
The gas hose is fitted to the gas fitting (GAS)
located on the front bottom panel of the machine.

4.4 MMA operation
The Raptor 180 TIG ACDC can be used as an MMA
welding machine by fitting an electrode holder
and work return lead to the respective dinse
connectors (dependent on the type of electrodes
being used).
When using your Raptor 180 TIG ACDC machine in
MMA mode, ensure that the TIG/MMA selector is
switched to the MMA position.
4.5 TIG welding operation
The Raptor 180 TIG ACDC is fitted with an option of
High Frequency (HF) start mode. The arc would be
initiated by keeping a distance of 2–4 mm between
the workpiece and the tungsten. The HF will be
initiated by depressing the contactor switch.
Once the arc is initiated, the HF will automatically
turn off.
