I was reading another post that mentioned a CV unit on a sa200. I was wondering about this? Constant Voltage? Is it a factory option or an add on? Do they only fit some? and how hard are they to find? This would make solid wire mig a lot easier.Bruce DeLaetHeavy Equipment Mechanic and Welder1948 SA-200 short hood1949 LincWelder 1801963 SA-200 red faceMiller S-32-P
Reply:Use to see them all the time. I think the SAM 400s and the Miller Trailblazer 55s did away with these. Attached ImagesDont pay any attention to meIm just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
