Check the proper operation of the thermal protection of the machine.

To check this:

Load

the machine with 45 A at %30 duty cycle. If the thermal protection does not activate within
approximately 5-6 minutes at this current value, something must be wrong with the thermal
protection. Contact the service in such a case. Otherwise, overheating may lead to a risk of
fire.

Make sure that the cutting current is according to the setting value. In case of difference,
readjust as this may affect the normal cutting operation.

Make sure that the cooling fan is not faulty and rotates normally. If the fan does not cut in
when the machine gets really hot, check if the fan impeller is stuck. If the fan is defective,
contact your service.

Check is the cutting connections are loose and overheating. Incase of overheating or
looseness, tighten them or contact to your service.

Check the current cable for damages. If damaged, wrap the damaged section with an
appropriate insulator or replace the cable.
