Error Cause Solution
1
When the machine is turned on, the power-on
lamp is off, the fan is working.
the power-on lamp is damaged, incorrectly
connected.
replace the indicator lamp, check the wiring
circuit.
the power pcB is damaged. repair / replace the power pcB.
2
When the machine is turned on, the power-on
light is on, the fan is not working.
the fan is blocked by a foreign object. remove the object.
the fan motor is damaged. replace the fan.
3
the power-on lamp does not light when the
machine is turned on, the fan does not work.

4 No output voltage at terminals. damaged power pcB. check the power section of the machine.
5 the arc cannot be ignited.
the welding cables are not
connected.
connect both welding cables.
the welding cables are damaged. repair / replace damaged cable.
the ground cable is not connected.
check the grounding cable
connection.
6 the arc is difficult to ignite.
Welding cables are incorrectly connected. check the connection.
the work clamps are covered with dirt. check and clean the work clamps.
7 unstable arc. arc power too low. increase the welding current.
8 the welding current cannot be set.
damaged control potentiometer or loose control
n-coder.
repair / replace potentiometer; pull the n-coder.
9 insufficient material penetration.
Welding current too low. set the correct welding current.
