sound generated by high

frequency

discharge,

“rubbing arc welding” can

start arc

2. The discharging electrode is oxidized or the distance is too long, pls remove

oxidized film or adjust the distance to 1mm.

3. Individual component of high frequency arc starting circuit is damaged, find it

and replace it.

4. The manual argon welding transfer switch is damaged.

Abnormal indicator lights,

and no output.

1. It may be caused by over-current protection, pls turn off the machine and restart

it after the indicator extinguishes, and the machine will operate normally.

2. It may caused by over-heat protection, do not turn off the machine, and wait

around 2-3 minutes, and the machine will operate normally.

3. It may caused by inverter circuit failure. Unplug the power terminal of master

transformer on the MOS board(near the VH-07 inserter), and restart the

machine.

a) if the abnormal indicator remains lighting, turn off the machine and unplug

the power terminal of high frequency arc starting power supply (near the

VH-07 inserter), and restart the machine.

i.

Individual MOFSET on MOS board is damaged if the abnormal

indicator remains lighting.

ii.

The voltage increasing transformer of high frequency arc starting

circuit in power supply board is damaged if the abnormal indicator

does not light.

b) Connect the power cord of failed inverter, and unplug the power cord of

master transformer, and restart the machine :

i.

If the abnormal indicator does not light, the transformer on middle

board may be damaged. Pls check the primary inductance and Q

value with bridge circuit.

ii.

The double-times rectifier of middle board may be broken through

individually, pls find it and replace it with a same model one.

4. It may be caused by short circuit in the feedback circuit.

Oxidized film on aluminum

workpiece surface can not be

exposed when welding.

1. Wrong position selection.

2. Insufficient duty ratio adjustment.

3. Double-times invert MOSFET is damaged.

Serious

burned

tungsten

electrode.

The duty ratio is out of specification, reduce it.
