I have been searching around the web and I need to find out just what the welder is I may be getting. It is an old miller But it is up on a high shelf and facing the wall.
Based on pic from the web it may be a millermatic 200. Looks like this from what I can see.

That looks just like mine. Mine is a 200 w/SKP. I picked it up at a School Auction for $150. It came with a Bernard gun. Only had to do a few minor things to it and it welds great. I use C25 on mine. Stripped it down, taped off the emblems and primered and painted it, Rustoleum Safety Blue. Very close to stock color.

We used the tri-mix gas in the structural shop until the last year when the new CWI switched over to argon/co2 90/10. At home I use C25 argon co2. I have a bottle of co2 that I pulled out when I exhausted the bottle of c25. CO2 is less expensive to buy but it does spatter more so be prepared that it does act a little differently than c25. C25 welds are "prettier". Watch CL for some deals. I bought 1 225cuft bottle and a 1 180cuft bottle for 150 bucks and exchanged them at the LWS. Great price!Argon / CO2 is the common mix, I use a try mix of Argon / CO2 / Oxygen. Forget the percentage of oxygen 3 or 5 . Gives a much hotter weld with better penetration for heavy sections but impossible to weld less than about 10 guage with it, way too hot.

I'll betcha that we purchased cylinders from the same guy........over in Independance? I've got 4 from him off of CL here in KC.We used the tri-mix gas in the structural shop until the last year when the new CWI switched over to argon/co2 90/10. At home I use C25 argon co2.
