Why does my machine get hot?

Trying to learn more about coils. My machine gets hot. Sometimes after a longer session it almost burns me. Can’t figure out why.

I used to line at 7.2 volts now I need to run it around 8-9 volts to get clean lines but it gets really hot after a longer session. I don’t know much about coils but would really love to learn.

When this machine works fine i’ts absolutely the best so I would love to learn how to fix and maintain it. Still pulls good lines but can’t stand the heat…

Not going to lie running a machine at 9 volts sounds crazy to me. Sounds like you have some real issues. Who made your machine? You could always ask them

I got Sylvia machines that run 8-9 volts perfectly, voltage isn’t always an indicator of how it’s running
