Trouble
Reason
Solution
The malfunction of the welding gun switch.
Check the welding gun switch,
control cable and aero socket.

No gas flow (TIG)
Gas cylinder is close or gas pressure is low
Open or change the gas cylinder
Something in the valve
Remove it
Electromagnetic valve is damaged
Change it
9
Gas always flows
The gas-test on the front panel is on
The gas-test on the front panel is
off
Something in the valve
Remove it
Electromagnetic valve is damaged
Change it
The adjustment knob of pre-gas time on the
front panel is damaged
Repair or change it
10
The welding current cannot
be adjusted
The welding current potentiometer on the
front panel connection is not good or
damaged
Repair
or
change
the
potentiometer

The
welding
current
displayed isn’t accordant
with the actual value.
The min value displayed isn’t accordant with
the actual value. (Please refer to
§
3.1)
Adjust potentiometer Imin on the
power board.

Adjust potentiometer Imax on the
power board.
12
The penetration of molten
pool is not enough.
The welding current is adjusted too low
Increase the welding current
The arc is too long in the welding process
Use 2T operation
13
The alarm lamp on the front
panel is on
Over heat protection
Two much welding
current
Reduce the welding current output
Working time too
long
Reduce the duty cycle (work
intermittently)
Over-voltage
protection
Power
supply
fluctuates
Using the stable power supply
Low-voltage
protection
Power
supply
fluctuates
Using the stable power supply
Too many machines
using power supply
in the same time
Reduce the machines using power
supply in the same time
