I've been using CO2 for welding for years witout any problems (including the the whole front end suspension setup on my truck). Reason for me is price (monopoly actually on propper welding gases up here, only one company sells them, and only rents out the containers at a redicilus price).Probably not as clean as using propper gas (or strong), but who cares when your welds are way longer and stronger than any factory weld on the truck anyway.
What about the difference in penatration? I've been told that CO2 creates a 1/2 circle where the mix makes a canyon.
Its hard to explain without showing, but most welds, the strength is in the weld re-enforcment itself, not how much it penetrates.
that's interesting, I've been taught the complete opposite. lola strong weld should be fully penetrated with weld reinforcement no more than an 1/8''.
Anyone know if praxair will let me swap out my co2 for a c-25 bottle, and if they do, is there a fee?
I run 15-25 psinever seemed to help to have more pressure, except if Im welding out in the wind
