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.
No output voltage.
check the network connection.
overvoltage in the network.
check the network connection.
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.
the arc is too small.
increase the welding current.
10
the fault / overheat indicator is on.
overheating of the machine.
use interval welding.
operating/duty cycle was too long.
Wrong output voltage.
check / replace the power section of the machine.

Make sure the following parts are not defective:
• main switch of the grid
• power socket and main power switch
NOTE:
despite your required technical skills necessary to repair the
generator, we recommend contacting trained personnel and our technical
service department in case of damage.
Routine maintenance and inspection
check according to eN 60974-4. always before use the machine to check the
condition of the welding and supply lines cable. do not use damaged cables.
perform a visual check:
• Welding cables
• power grid
• Welding circuit
• covers
• control and indicator elements
• General status
