What does the tempering main operator mean?

Hello, the tempering operator mentioned by the landlord is actually a technical operator in a process of producing tempered glass in the glass deep processing factory.

From the landlord's question, I know that I have never been in contact with the glass industry. So you can't go to the post of tempering master as soon as you enter the glass factory.

Perhaps the personnel department of the glass factory thinks that you are young and know computers, so it is suggested that you can be a tempering master in the future, but only if the master needs to take you. Because the main operation involves technical parameters, this is the position that needs operation and accumulation in the work to reach the main operation.

Since the glass factory proposed this to you, you should put down your attitude and study hard. This is a technical job. I have learned that there are thousands of dollars in salary in any tempered glass factory.

We are a glass deep processing enterprise in Chengdu, Sichuan.
