Late night typo
Sorry for the miscommunication, I use C25 with my mig, and 100% argon with tig.

CO2 in your GTAW gas will contaminate your tungsten, among other things.

Thanks for the tips
My mistakes were many! First and foremost, with TIG or MIG using solid wire and C25 - I pay more attention to the weld pool. With Flux cored - the smoke distracts me... so I rush the weld. I'm going back to basics and burn stick welds for awhile.
I think most of us see the course welds in parking garage staircases and think I can do better then that, and see the tight quality welds on high end prducts and wish we could do those.
I'm teaching myself how to weld - and as bad as my first welds look. My RV storage compartment is still on my bumper after 3000 miles without any stress cracks.
I like Arcin' & Sparkin'

Flux or not, some still require a shielding gas, usually CO2, because the core is designed more for cleaning and penetration and deposition than it is designed for shielding.
Good question. For the most part, you'll have to be specific (and be at a real welding shop) to get these dual-shield wires. When you just ask for "flux-cored," or if your at Home Depot, Harbor Freight, etc, you'll just get the standard "gasless" stuff, what Lincoln calls Innershield.

Originally posted by sjmillerI coulda and shoulda switched to solid wire and C25 gas - I got lazy and used the flux cored wire that was already loaded.

Reference book
I received my copy of the Larry Jeffus Welding Principals and Applications (Fifth Edition) a couple of days ago from Amazon. I have spent the last three nights parsing the 825 pages of text - it is the most complete reference I have come across. It explains the why, and the how of welds - and then numerous practical exercises - from horizontal to vertical to overhead procedures. It covers sheet, plate, pipe, and welding processes I'll never touch.
I highly recommend this book - it's not cheap, it is an authorative reference for those of us that haven't attended formal welding apprentice programs.

Kudos
Hey Steve good on ya. it takes some spine to self school anything. I am also new to metalworking and was just looking at the cutting pan picture myself. I think it will be my first home project.
Good luck in your endeavor

Plasma cutter
I just received my Spectrum 375 plasme cutter, and had to test drive it. I'm home schooling myself in metal working and to be honest was surprised at how it slices and dices steel - like butter. I had been using a high speed Makita angle grinder for all of my cuts for the last two years.
Thanks to Rickey D for the plasma cutting pan idea - unfortunately - my crappy welds leak. The leaks are more of an insult - about one drop every 4 hours... I coulda and shoulda switched to solid wire and C25 gas - I got lazy and used the flux cored wire that was already loaded.
Now I'll TIG the seams on the pan - it's only 18" X 18".
