I've become comfortable with a mig machine but want to learn tig. I've read just about everything I can find and want to try to do a little work on mild steel to get my feet wet. Is there a setup that might be a little more forgiving for a novice in terms of,
I'm using a Miller 180 SD.
Thank you. VRS
Go to your local steel supplier/fabricator and buy some steel rems.
Get the instruction book.
Weld.
Weld.
Weld.
When the light bulbs start coming on, go get some SS rems. You can do them with the same equipment as regular steel.
When you are ready, and if your machine will do it, go get some aluminum rems.
It's all practice and following directions.
If you know a welder who can coach you, that is a good thing. If you have a community college in your area, they usually have some good programs that are cost efficient in helping you learn.
Your local welding supply store is usually full of ex welders, too who can help you pick out the right supplies and the right settings.

That and get the set of welding calculators (slide charts) from Miller for the $5 or so (you can find and order them on the Miller site). Great for finding a starting point for any given weld.

I prefer 34B. Less than a handful, not much more than a mouthful. Juuuuuuuuust right!
Also, go to
Lincoln has knowledge articles there, too.
Now stop by
I'm at this early re-learning stage, too, with a little tigger from Harbor Fright.
--snip of more good suggestions--
I just got those and they're only $4 _delivered_! Great deal.
How is that $200 Tig working out for you? I sure was tempted for the bucks.

Real well, though I haven't done much with it yet. Now that the temps are climbing a bit, I'll have a chance to get out there a bit more. The flu took 1.5 weeks away from me, and I've been reviving a dead computer this week, then the pipes burst to my landscaping plumbing last week. I still haven't repaired those or done my taxes yet.
So many projects, so little time...
Go to google groups and look in this news group for messages from Ernie. Every once in a while he posts his list of links and also his recommendations on tig tungstens and current to use for various thicknesses of metal.
I would start with 1/8 inch steel. Thick enough to not have problems with holes and thin enough to not require lots of heat.

Tell me about it

Hiya Larry, Like you, I have a million projects going. One is to learn how to MIG weld without classes (none in the area that work for my schedule). Anyway, I'm also interested in learning TIG so give us a short review of this unit when you have a chance to "kick the tires" so to speak if you don't mind. Cheers, cc
