best body work GMAW shielding gas?
Is c25 best of straight Co2? It is only a 110v welder so i'm thinking i could get away with 100% with out too much trouble. but c25 would probably be better with the shallower penetration and minimized spatter. what do you think?
thanks, Justin |

Stick with the mix. you don't need straight CO2 Either one will work but for thin gauge sheetmetal I would just use the mix. If you already have it, as it sounds it will work

Re: best body work GMAW shielding gas?
I believe the c02 is for penetration and the argon is used for anti-spatter. Some people like the 90/10 mix I have always used the 75/25 but I am thinking I will try out the 90/10

The more argon, the better. 75/25 is the best compromise between added cost vs. gains. That is why that is the industry standard for mig welding.

The 75/25 is a very common mix. We use a 85/15 mix here at school. Both have good penetration and yet are relatively spatter free when set right.

Re: best body work GMAW shielding gas?
I know in my highschool job we used 90/10 but we were welding on nasty pipe, and needed penetration. I have never used 75/25 before though.
