MAINTENANCE & TROUBLESHOOTING

S/N

Troubles

Reasons

Solution

The adjustment knob of pre-gas time on the

front panel is damaged

Repair or change it

The welding current can not be

adjusted

The welding current potentiometer on the

front panel connection is not good or

damaged

Repair or change the potentiometer

No AC output while selecting

“AC”

The power PCB is in trouble.

Repair or change it.

The AC drive PCB damaged.

Change it.

The AC IGBT module damaged.

Change it.

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.

The max value displayed isn’t accordant with

the actual value. (Please refer to

3.1)

Adjust potentiometer Imax on the power

board.

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

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

Over-current

protection

Unusual current in

the main circuit

Check and repair the main circuit and

drive Pr6
