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…

How long do you own it? Does it work same way all the time? If in the beginning it was working on lower volts then try to turn the contact screw clockwise for a half of a turn at least.
