Welding question

What you probably saw was GTAW, Gas tungsten Arc Welding, old name of Tig. The gas welding rod you refer too is called filler rod. Yes Tig can be used on SM very well.

Tig is a very precise controled arc when comparred to all other welding processes. Cycle frames use thinn metal tube along with a small diameter. With other welding processes it's difficult to control weld penetration as well as weld puddle size and contour on this type of weld application but with the Tig process both can be easy achived.

I've written several articles on Tig welding on this forum. Do a search for, T_Bone, and you'll find them easy.

If that don't answer your questions post back with your new questions.

I have a miller syncrowave 180SD, it does TIG and Stick. Argon is sooooo expensive and once I learned both ways, I use stick almost all the time. TIG is great for aluminum but for steel, save yourself some money and go with stick. You have to clean up after but it is much faster and cheaper. Also if current is an issue, I can easily weld 1/2 plate with stick but tig takes twice the current to do the same thickness.

Try getting on the miller web site, www.millerwelds.com

They should have some info for you about the various processes.
