TROUBLESHOOTING

The following operation requires sufficient professional knowledge on electric aspects and

comprehensive safety knowledge. Make sure the input cable of the machine is disconnected

from the electricity supply and wait for 5 minutes before removing the machine covers.

Before arc welding machines are dispatched from the factory, they have already been checked
thoroughly. The machine should not be tampered with or altered. Maintenance must be carried out
carefully. If any wire becomes loose or is misplaced, it maybe potentially dangerous to the user!

Only professional maintenance personnel should repair the machine!

Ensure the power is disconnected before working on the machine. Always wait 5 minutes after power
switch off before removing the panels.

Description of fault

Possible cause

The digital display is OFF and the fan
is not functioning

The primary supply voltage has not been switched ON or
input fuse has blown

The welding power source input switch is switched OFF

Loose connections internally

The digital display is ON but the fan is
not running

The machine fan blades may be jammed

The machine fan may not be functional

Check the wiring and the supply voltage to the fan

Wire feed motor does not rotate

Check wire feed speed, to ensure its not set to zero

when the MIG torch trigger switch is

Check supply to wire feed motor

depressed

Possible motor PCB fault

Output current reduces when welding

Poor work lead connection to the work piece

TIG electrode melts when arc is struck

TIG torch is connected to the (+) VE terminal

No gas flow when the MIG torch
trigger switch is depressed

Empty gas cylinder

Gas regulator is turned off

Gas hose is blocked or cut

Torch trigger switch lead is disconnected or switch/lead is
faulty

Difficult to ignite the arc

The welding voltage is too low or the wire feed speed is set
too high

The electrode holder becomes very
hot

The rated current of the electrode holder is smaller than its
actual working current, replace it with a higher rated current
capacity

Excessive spatter in MMA welding

The output polarity connection is incorrect, exchange the
polarity

Other malfunction

Contact your supplier

Overheat error code lights up

Let the machine cool, it will automatically start again

Insufficient cooling air

Cooling fan is not running

Wire continues to feed through when
the MIG torch switch is released

The trigger mode switch is set to 4T rather than 2T

Faulty MIG torch switch
