I have a question about my Arc-Tec 300 but there doesn't seem to be a section for it. 
This may seem a basic question but I have been welding professionally for nearly 40 years but still don't know what the difference is between the three tappings marked A B & C.
I have never bought a new welder, they are always second hand and just leave the tappings as they come but really started to wonder what difference they make. I have tried all three but I can't see any significant difference.
The welder is three phase and 300 amp.
