Wife got me a couple of welders for Christmas. Lincoln Pro mig 175, and Lincoln tig 185. Haven't even attempted the tig yet. I have been trying the mig process. Tried to make a welding table from 3/8" mild steel, it had a red powder looking rust preventive or something. The square tube material had blue paint or something on it. I bought 100% argon to try on both welders. I had a hard time with the mig with this. I put some flux cored wire on and it welded pretty good, well stuck the parts together. What gas mixture should i use for migging mild steel, and is there a mixture i can use for both welders?fEETSLast edited by feets; 04-03-2007 at 03:55 AM.
Reply:75% argon 25% Co2 premix works best for mig and straight argon for tig. If you clean off all paint, oxide and dirt you will be amazed at how much better it welds.Whatawoman!DavidReal world weldin. When I grow up I want to be a tig weldor.
Reply:for mig hard wire i use 90/10 gas and mig flux core 75/25!
Reply:Argon for TIG.See link for info on various MIG gas mixtures.http://files.aws.org/wj/2006/02/wj20...j200602-46.pdf
Reply:Cleaning your material first makes a ot of difference. You can do both processes with straight argon but with the mig the bead will be narrow and have a high profile. I'd definitly invest in another bottle for mixed gas. You must have one of the greatest women in the world.DewayneDixieland WeldingMM350PLincoln 100Some torchesOther misc. tools
Reply:you can get a small 20lbs bottle of strait Co2 prity cheap for the MIG and use the strait argon for TIG. C-25 as mentioned above is also an option but a lil more expensive. i recently switched from c-25 to strait Co2 and am verry happy with the results. flux core needs no gas.reguardless of witch welder or gas you chose you realy need to clean the crap off the work first. congrats on the new toys, good hall. summer is here, plant a tree for mother earth. if you dont have time or space, sponcer some one else to plant one for you.feel free to shoot me a PM or e-mail me at [email][email protected]

Reply:Your wife got you 2 welders for Christmas and your asking us for advice? Looks like you're good at figuring things out.But for what it's worth I use 75/25 argon/CO2 for sheet metal and straight CO2 for 1/8+ thick steel.
