Welding a Small Part

downsizingnow48 · Jun 4, 2015

Many thanks for detailed suggestions. I do have a stick welder, old Thunderbolt AC/DC, but no TIG.

I think I will use the MIG (Miller 211), corners first, then faces, .023 wire.

I was just going to let it cool in the air but I can drop it in a bucket of oil if there is an advantage to that.

Actually,Pat there's no reason for not gas wring it either. You could do as neat a job as tig.

It's a good idea, as it helps restore the proper hardness to the steel.

I started out gas welding in my Dad's shop when that was all he had, so that is what I think of first even though I guess it is pretty much obsolete!

I have a Miller MM210. Plenty of machine for the task at hand. I'd use .030, but .023 will work just fine. You COULD use oxy/ace to weld this, but it would not be my first, second, or third choice.

The oil is an old trick that a guy who makes custom springs taught me. I used to just cool things down with water and you do get some tempering, but the oil works much better. Now on larger pieces you just have to let the air cool it down and be more careful with over heating.

you are about $100 away from having a scratch start TIG rig with your Thunderbolt if you rent your argon cylinder.

I just bought this scratch start Tig torch a couple months ago. Really like it.:thumbsup:

there you go. If you want a 17V 150 amp torch they are somewhat cheaper. But in any case for around 100 bucks more or less, you are welding TIG.. if you cant rent a bottle. If you have to buy the argon cylinder, well add some more.. depending on the size you buy.
