Upgraded my welder to MIG, CO2/ Argon mix. PSI recommendations Options

[Socalandy]

With all the welding (IMG:style_emoticons/default/welder.gif) coming up on the -6 car I purchased the MIG conversion kit for my Lincoln. It is much cleaner and has better penitration but I'd like to get some feed back on where to set the PSI for the CO2/ Argon mix. Want to have enough but not waste it either.

seems to work well on 16 gage steel with 20psi

Holy beegeezus !! You guys are wasting ALOT of gas !! 12-15 cfh is ALL you need unless you are welding outdoors. 75/25 mix, .023 wire and 15psi is all you need for anything on a 914, unless you get to welding on the suspension. Even then you won't need any more gas flow, just larger wire and higher amperage.

And for all you folks that think you need to buy a 300 amp machine, all I have at the shop is a 140 Miller MIG and it is all I need on a car. I do have a 250 at home and a 200 amp tig, but the 140 mig is all I use at work for body work.
