Robert,
Thanks for the info. I went back to read the information that came with the welder. There really wasn't a preference for CO2 over the Argon/CO2 mix. Sorry for putting that info on the forum. It was more like they were the same. They do specify a higher temperature and faster wire feed rate for straight CO2.
I appreciate the help and advice from an experienced welder. I will look into getting some of that wire. There is a pretty good size welder's supply in the area.
