I attended class yesterday for the MIG session of the welding course. The first part was the instructions on how the settings are set and that they are different on every machine. How to change a wire and what to look out for with the roll. The teacher requested us to change the wire so if we have any issues we can get his assistance to fix them. I did that and it was easy to do. Only consideration that he mention was not to let the wire go when changing the roll.
I understand how easy it is using a MIG welder as to Oxy or Stick.
