Your arc welder is simple and durable, requiring virtually no maintenance other than the guidelines shown
below:
• Keep the ventilation holes clean to avoid the build-up of dirt inside the machine, this can reduce
machine output.
• Check all cables periodically; they must be in good condition and not cracked.
• Always try to avoid getting particles of metal inside the machine since they could cause
short circuits.
• Periodically clean the inside of the welder with compressed air.
This chart will assist you in resolving common problems you may encounter. These are not all the possible
solutions.
PROBLEM
POSSIBLE CAUSE
POSSIBLE SOLUTION
Temperature LED Indicator
is on
Poor ventilation can cause over-
heating
Ambient temperature is too high
Using over the rated duty-cycle
Improve the ventilation
It will automatically recover when
the temperature decreases
The adjustment knob on
the front panel didn’t work
Potentiometer broken (current
regulation)
Replace the potentiometer.
Cooling Fan not working
or turning very slowly
Switch broken
Fan broken
Wire broken or falling off
Replace the switch
Replace or repair the fan
Check the connection
No no-load voltage
Over voltage, under voltage or
scarcity of phase
Welder getting overheated
Switch broken
See “Yellow Indicator is on”
Replace the switch
Electrode Holder and
Cable getting hot; “+” “-”
polarity sockets becoming
hot
Electrode holder’s capacity is too small
Cable is too small
Socket loosen
Increased resistance between the
electrode holder and the cable
Replace it with a bigger capacity one
Replace it with another one in
conformity with the requirement
Remove the oxide skin and tighten it
Power source tripping
Resume power over a long period
of time (more than two days)
In the process of welding
Trip caused by the main power
filter’s capacity charging. Switch on
the main power source.
