Definitly brought up a good point Scooby..I may cut my loss's on this wire and just get a spool of regular soild core with mig mix gas..Either way i will keep the info on lease big tanks and owned smaller ones at hand when i call praxair..
Sheilded arc. welder is cv-300 with an ln-7 feeder with the serrated rollers. Wire size is .045. I am not in a high production welding enivorment( altho i can lay some serious weight when required with this welder). I mostly just build trailers, splitters, fix stuff and general fabrication but recently have needed to have cleaner welds for cosmetic reasons..
