S/N
Troubles Reasons Solutions
1
Turning on the power source, and
fan works, but the power light is
not on.
The power light is damaged, or connection is
not good
Test and repair the inside circuit of
power light Pr3
Power PCB failures Repair or change power PCB Pr2
2
Turning on the power source, and
the power light is on, but fan
doesn’t work
There is something in the fan Clear out
The fan motor is damaged Change fan motor
3
Turning on the power source, and
the power light is not on and fan
doesn’t work
No input voltage Check whether there is input voltage
Overvoltage (Input voltage is too much or not) Check input voltage
4 No-load voltage output There is a problem inside the machine Check the main circuit, Pr1 and Pr2
5
No current output in the welding
process
Welding cable is not connected to the two
outputs of the welder.
Connect the welding cable to the
welder’s output
Welding cable is broken
Wrap, repair or change the welding
cable
Earth cable is not connected or loose. Check the earth clamp
6
Not easy to start arc or easy to
cause sticking
The plug is loose, or connection is faulty. Check and tighten the plug
Oil or dust covered the workpiece Check and clear out
MMA/TIG welding selection is wrong Selecting the MMA welding
7
The arc is not stable in the welding
process
The arc force is too small Increase the arc force
8
The welding current can not be
adjusted
The welding current potentiometer in the front
panel connection is not so good or damaged
Repair or change the potentiometer
9
The penetration of molten pool is
shallow (MMA)
The welding current is adjusted too low Increase the welding current
The arc force adjusted too small Increase the arc force
10 Arc blow
Airflow disturbance Use the shelter from airflow
The electrode eccentricity
Adjust the electrode angle
Change the electrode
Magnetic effect
Incline the electrode to the opposite
way of the magnetic blow
Change the position of earth clamp or
add earth cable in the two side of
workpiece
Use the short arc operation
11 The alarm light is on
Overheat protection
Over welding current Induce the welding current output
Working time too long Induce the duty cycle (interval work)
Overcurrent
protection
Unusual current in the
main circuit
Test and repair the main circuit and
drive PCB (Pr1)
