Fault symptom

The fan does not rotate, the

digital meter has no display, and

there is no welding output.

The fan turns, the abnormal

indicator light is not bright, there

is no high-frequency discharge

"sa sa sa" sound, and the "LIFT

TIG welding" can not start the arc.

Abnormal indicator light is off,

there is high frequency discharge

"sa sa sa" sound, no welding

output

Abnormal indicator light is not lit,

no high-frequency discharge "sa

sa sa" sound, arc welding can

start arc

Abnormal indicator light is on, no

output

1. Confirm that the air switch is intact or closed.

2. Confirm that the power grid connected to the output cable has

power.

3. The thermistor (four) on the power supply board is damaged (this is

usually caused by DC24V relay failure or poor contact contact).

4. The power board (base board) is faulty and there is no DC537V

voltage output.

5. The auxiliary power supply on the control panel has failed.

1. Check all kinds of patch cords in the machine for poor contact.

2. Control circuit problems, find the cause or contact the dealer.

3. The control line on the welding torch is broken.

1. The welding gun cable is broken.

2. The ground wire is broken or not connected to the welded

workpiece.

3. The positive output terminal or the torch gas output terminal is loose

from the connection inside the machine.

1. The primary line of the arcing transformer is in poor contact with the

arcing plate and is retightened.

2. The discharge nozzle is oxidized or the distance is remote. The

surface of the discharge nozzle is treated with an oxide film or the

distance of the discharge nozzle is about 1 mm.

3. Hand soldering argon welding conversion switch is damaged and

replaced.

4. The individual components of the high-frequency arc-trigger circuit

are damaged, and the replacement is found.

1. It may be overcurrent protection. Please turn off the machine. When

the abnormal indicator light is off and then restarted, it can be restored.

2. may be overheat protection, do not need to shut down for 2-3

minutes, the machine can naturally return to normal.

3. It may be that the inverter circuit is faulty. Please unplug the power

supply plug of the main transformer on the MOS board (near the fan

VH-07 plug-in) and restart it:

(1) If the abnormality indicator is still on, turn off the power plug of

the high-frequency pilot arc power supply (near the fan VH-03 plug-in)

and turn it back on:

a. If the abnormal indicator is still on, the individual FETs on the MOS

board are damaged.

b. If the abnormal indicator is not lit, the step-up transformer in the

high-frequency arc-rising circuit on the power supply board is broken
