Checking breakdown
Cautions:
The operators are supposed to have enough knowledge of electric-gas and
common sense of safety, and concerning certificates are needed. We suggest you contact us
before operation and meanwhile get permission
BREAKDOWN
1.No reflection after turn-on
2. The regulator indicates no
sound of releasing
electricity, no show of
breakdown.
3. Have HF
electricity-releasing, but no
current output.
4. Have current output, but
cannot adjust,
5. Hand-control normal, while
foot switch abnormal.
6. Abnormal pilot light on
7. Can not remove the
oxidized coating in
AL-welding
8. Current normal, but no gas
out
9. Tungsten terribly damaged
10. Earth cable too hot
If you still can not solve the problem after consulting the above table, then please contact the
sales agency or concerning department.
.
POSSIBLE CAUSES
1. No power supply or
short of phase
2. Power cable in break
circuit
3. Assistant power off in
the phase
1. Something wrong with
the switch
2. Releasing nozzle in
short circuit
3. Air-socket wrongly set
up
1. Earth cable not well
connected
2. Torch cable in short
circuit.
1. Hand-control and foot
switch in wrong place.
2. Potentiometer in the
foot switch broken.
1. Slight switch in foot
switch broken.
2. Sliding potentiometer in
the foot switch broken.
1. Spontaneous
over-current protection.
2. Too much dust causes
short circuit.
3. Some parts in the
machine broken.
1. Choose the wrong
welding button.
2. Clear width too low.
3. Damage the MOSFET in
second inverter.
1. Have sound of
electromagnetic valve
a. Gas nozzle blocked up
b. gas hose broken
2. No sound of
electromagnetic valve
a. Valve damaged
b. Valve-controlled circuit
in trouble
Clear width adjust too
much
Earth cable not well
connected
SOLUTION
1. Check the power supply.
2. Open the case to check the voltage
3. Contact the supplier or specialist.
1. Use screw knife to make the two- cored
air socket short circuit.
2. Adjust the distance between
electric-releasing nozzles.
3. When using torch or foot switch, the
concerned plug should be in the two-cored
socket.
1. Check the earth cable.
2. Check or renew the torch.
1. When using foot switch, the exchange
switch should be in "on" place.
2. Renew the potentiometer.
1. Renew the slight switch.
2. Renew 1K sliding potentiometer.
1. Turn off the machine, and restart after
the light on.
2. Open the case; use the compressed air to
clear the dust.
3. Contact professionals or suppliers.
1. Choose AC button in AL welding.
2. Make clear width high or remove the
oxidized coating.
3. Contact professional.
a. Clear the blockings.
b. Repair and change Tig torch
a. Change the valve.
b. Ask professional to repair the board.
Adjust the clear width in counterclockwise
Better tie the cable screw to the work table
