depressed.
A
B
Power source is not in the
correct mode of operation.
Faulty torch trigger.
A
B
Set the power source to the correct mode of
operation with the process selection switch.
Repair or replace torch trigger switch/lead.

ON. Indicator light is not lit
and welding arc cannot be
established.
A
B
Primary control fuse is blown.
Broken connection in primary
circuit.

electrical contact.
6 Welding output voltage is not
present when torch trigger
depressed
Faulty trigger switch / lead Repair or replace Torch / trigger lead
7 TIG electrode melts when
arc is struck.
TIG torch is connected to
the Worklead terminal. Connect the TIG torch to the Electrode
terminal.
8 Arc flutters during TIG
welding.
Tungsten electrode is too
large for the welding current. Select the correct size of tungsten
electrode.
