2.0 Product Description
This welding machine is manufactured using advanced
inverter technology. The input voltage is rectified to
DC and then inverted to high frequency AC voltage.
before being converted back to DC for the output .This
allows the use of a much smaller transformer and so
allowing weight saving and improved power efficiency.

4.0 Description of Controls
1) ON OFF Switch
for switching on or off the mains
supply to the machine. Note the output of the
machine is permanently on in MMA mode unless the
on/off switch is in the off position.
2) Gas input connection
3/8 BSP male connection for
TIG welding Gas.
3) Water input connection
, input of cooling water
when using a water cooled TIG torch.
4) Power light
This indicates mains power is applied
to the machine and that the machine is currently
switched on when the light is illuminated
5) Fault light
This indicates a fault or over temperature
condition with the machine refer to the fault finding
section for further information
6) TIG mode
, this toggles between LIFT-ARC mode and
HF start TIG.
7) Process selector switch
. This switch has 3 positions
the top position selects MMA welding and will latch
on the output when in this position. The centre
position is TIG welding with 2 touch trigger control
(momentary). The bottom position is TIG welding with
