Is it more difficult to learn how to plug socks or how to sew the head of a disc?

It varies from person to person, depending on which one you are more interested in.

Sock machine plug is a manufacturer of socks. What kind of yarn does the hosiery machine need? What color is the yarn? After connecting the yarn as required, you can start the hosiery machine. When the hosiery machine is running, a semi-finished sock will be woven. During the operation of the hosiery machine, the yarn sometimes breaks. If the yarn breaks, the hosiery machine will stop running. There are many reasons for yarn breakage, such as weakness or coarseness. As long as the yarn is connected, the machine can be restarted. When the hosiery machine runs at high speed, the knitting needles will weave defective socks, such as small holes or vertical bars, due to coarse sand or sudden failure of the machine, so it is necessary to stop the machine and inform the mechanic to deal with it. It's actually quite simple. It is not difficult to learn by heart. You can learn it in a day.
