Set the power source to the
correct mode of operation with
the process selection switch.
Connect 8 Pin TIG Torch control
plug securely and correctly to the
8 Pin control socket of the front of
the Power Source.
Ensure that the Work Lead is
connected to the work piece and
has a good connection to the
work piece. Refer to Set Up for
TIG Section 5.02.
Repair or replace torch trigger
switch/lead.
2 Mains Supply Voltage is On,
the On/Off switch on the rear
panel is in the On position
and the Power indicator on
the front panel is illuminated
however the power source
will not STICK weld.

B
Set the power source to STICK
mode. Refer to Section 6.01.
Ensure that the Work Lead is
connected to the work piece and
has a good connection to the
work piece.
3 Fault Indicator is illuminated
and unit will not commence
welding when the torch
trigger switch is depressed.
Duty cycle of power source has
been exceeded.
Leave the power source
switched ON and allow it to
cool. Note that fault indicator

Source is repeatedly switched
On then Off rapidly or the
supply to the Power Source is
switched On then Off rapidly.
If this occurs leave the Power
Source On/Off switch in the Off
position for several minutes to
allow the protective device to
reset.
