Plasma controler turns very hot when is working

[rulreyes200]

Hello. My name is Raul and I am a user of a plasma cam table Samson modelo 510. The problem that I have is that when I start working the machine the controler start to increase its temperature at an extreme point of 70 C. I think that is no normal and I am looking here if there are any personas that could help me to solve this problem. Thank you so much!
