5.0 Troubleshooting

If there are simple troubles with your MIG160 welding machine, you can consult the following overhauling chart:

When the machine is powered
on, the fan works but the
power light is not on

Light damaged or has a bad
connection

Power PCB Failures

Test/repair the inside circuit of power
light
Repair or change control panel

When the machine is powered
on, the power light is on
but the fan doesn’t work

There is something in the fan

The fan motor is damaged

Clear out

Change fan motor

When the machine is powered
on, neither the fan or power
light work

No input voltage

Check whether there is power supply

The fuse inside the machine
is damaged

Change it (10A)

No no-load voltage output
(MMA)

The machine is damaged

Check the main circuit

The max and min value
displayed doesn’t match
the set value

No Gas Flow (TIG)

Something in the valve

Gas cylinder is closed or gas
pressure is low

Electromagnetic valve is
damaged

Remove it

Open or change the gas cylinder

Change it

The displayed current on the
screen doesnt match output

The LED screen is broken

Change the LED screen

The welding current can
not be adjusted

The welding current
potentionmeter in the front
panel has a bad connection
or is damaged

Repair or change the potentionmeter

The penetration of the molten
pool is not enough

The welding current is
adjusted too low

Increase the welding current

Gas always flows

Something in the valve

The gas test on front panel is on

Electromagnetic valve
is damaged

Remove it

Turn off

Repair or change it

The alarm light is on

Over heat
protection

Over current
protection

Over welding

current

Working time

too long
Unusual current
in the main
circuit

Reduce the welding current output

Reduce the duty cycle (interval work)

Use a stable power supply/ ensure

not too many machines are using the

same power supply

S/N
