I need a controller board for Chicago Electric 200 amp mig
You may not need to replace the board if the wire feed failed- most often it is an SCR or pair that has failed. Usually what is used is a 6 amp 600 volt SCR- you can go higher current and voltage for reliability. just make sure the heat sink is adequate or larger and heat transfer compound is used. Digi Key carries the "Teccor" SCR's other brands of the same or higher ratings will work.
