Machine Heating issue

[AcombativePYRO]

Hey guys Im a self taught artist. I recently just bought a new set of machines. Payed quite a bit for them. Im not going to say what brands so I rule out the personal negatives of the actual brand.

Any way i WILL say that I am using a finely adjustable LCD power source. I use both 8 coil and 11 coil, My 8 coil as a liner never over heats, works sounds smooth as hell,

Yet, my 11 coil I shade and color with SOUNDS amazing, put ink in like crazy ect. except. It over heats. Now I could go by my CPS Hz FT ect ect but I have learned to go by the sound of the machine and depth of the throw.

Does anyone know why I am overheating? It will get to the point where I have to tap my machine to get it to start dancing.

I am kind of new to the 11 wrap coils. Do they just run hot?

Thanks for your info guys.
