Over-heat protection ,too much
welding current
Reduce the welding current
Reduce the welding time
Over-heat protection ,working too
much time
Over-current protection, current in
the main circuit is out of control
Tig torch is connected to the
positive terminal
Tungsten electrode is too big for
the welding current
Check the earth clamp position on
the work piece
Check and repair main circuit
and drive board
Connect the tig torch to negative
terminal
Adjust the position of earth clamp
Select the correct size of tungsten
electrode
Thermal overload
indicator light is on
