Common faults and what to check first
Machine is dead or does not power on
Check the input supply and fuses first. A failed input or auxiliary supply on the board is a common cause.
Trips or blows the fuse
Often a power-stage fault. Do not keep restarting the machine; note what trips.
Overheat or fan error
Check the fan and airflow first, then the power stage and sensors.
Unstable arc or wire-feed problem
Control board or feedback fault. Tell us the process and the error code.
