Tig welding question

I am new to tig welding so bear with me,being so new I will need a ton of practice and I know that.What I am wondering is say I make tac welds with a mig can I go through and TIG weld them after or will the area e "contaminated" to much to tig weld it after?

What type of mig? Flux will interfere with your TIG setup. I pretty much TIG everything we do at work. I would go for it and see, personally I prefer the TIG to all other welding processes anyways.

You can tack with a mig and then tig over top of it when you go to finish the weld with no issues. Flux core welding isn't mig welding meatlord. Not trying to be an ***, I just don't want any confusion for the OP.

I have used many wire feed setups with flux core wire on the same machine without the gas. Guess I did not specify that.

I've TIGed over MIG tacks, doesn't seem to be a problem. I imagine you could probably TIG over a flux core tack as well, so long as you chip off all of the slag and wire wheel/brush it good? I've not tried it though.

Here's a trick I've seen before: if you're out of tig rods, take a length of mig wire, fold it in half and twist it up tight with a drill. Bam tig rod in a pinch.

Wire hangers work shockingly well too. They are made out of such a mishmash of metals that they work on damn-near anything in a pinch. I personally wouldn't do any critical welding with one but for an at-home repair or an emergency they are great. Try running a few beads with one for S+G's.

They are pretty hard and usually have that nasty coating on them. Why not bailing wire instead? Crappy steel also but no coating and softer.

A friend uses his torch rig to take that nasty coating off of coat hangers when he needs one. Just get it red hot for a second but don't breath the fumes as who knows what that stuff is??? Probably OK for general repairs but not structural welds IMHO. We mainly use ER-70S & ER-80S rods on 4130 metals.
