Urgent! ! ! ! ! ! ! ! ! ! ! ! ! ! Overheating of Koike Acid NC Plasma Cutting Machine

I am a manufacturer of CNC cutting machines, and I want to correct and supplement the opinions upstairs:

1. thick plate is usually suitable for flame cutting.

2. The high temperature alarm may be caused not only by the high temperature of the cutting torch, but also by the heat dissipation of the control system. Better check the industrial computer.

Make the following inferences based on your supplementary information:

1. The internal circuit of the drive motor is partially short-circuited, resulting in excessive temperature.

2. The motor load is too high. Has the previous mechanical structure been changed? Or is there a problem with lubrication?
