Help w/. Chinese on Jewlry Welder

[m3sca1]

Any assistance translating the labels would be fantastic.
These labels come from a machine I bought off Ebay from China. It seems to work as described but I have no idea what the knobs are meant to do. I am thinking they would be maybe something like power and pulse length.

1) Fine tuning/adjustment. 2) Normal tuning/adjustment.
