Hello all, Please forgive me if this is the incorrect place to ask this question, yet I happen to own an Ungar 4024 solder/desolder station that I would like to use for PCB work. While the system uses an analog (slide) control for temperature variation, the numbers listed on the slide are 1-4 and do not list respective temperatures. Does anyone happen to know where I can get data on what temperatures correspond to the 1-4 (such as an Ungar 4024 manual) before I try to find out via trial and error? Thank you! I appreciate the time and help.
