11. BEFORE CALLING FOR THE SERVICE
In the event of a malfunction of the machine, before sending the welding machine to the service center, check the list of basic faults and try to
remove them yourself.
All repairs to the device may only be carried out after disconnecting the plug from the power socket.
Warning! The device is not sealed and the user can remove the welder housing to remove minor failures.
symptoms
Removal methods
The control panel does not light up,
the fan does not work, no output
voltage
1. Make sure the switch is in the ON position
2. Check the protection and voltage in the network
3. Remove the cover and check the connection of all electrical plugs inside the device
The control panel lights up, the fan
does not work, no output voltage.
1. Check whether the device has been connected to a higher voltage network. If so, connect
to 230V and switch on again
2. The supply voltage is unstable and turns on the overvoltage protection. Turn off the device for 2-3
minutes and turn it on again
3. Briefly turning the switch on and off resulted in overvoltage protection being turned on. Turn off the
device for 2-3 minutes and turn it on again
4. Other damage has occurred that requires repair by an authorized service center
