i can only find one guy locally here in rural west tn he has a 110 tig welder

will this be enough to weld these? will it make any kind of penetration?

inside the hole is a drill bit end

Without seeing it, probably. The guy next door has a 120v Mig outfit and welds all kinds of stuff with it. He could does 1/8 and some 1/4  inch nicely.  IMO Tig is best for what you're doing, you have better control and great for welding dis-similar metals plus not going to use burn it up with too much heat. If your guy is confident in his ability it should be fine and no or little grinding.  

I have an old 240Volt Arc (stick) AC welder which is brutal on finer stuff. DC mode is best for out of position welding like overhead and in-position or in position stuff like pipe welding (that can't be moved) where AC is limited to horizontal and flat only.  I always wanted to get a Tig/Mig outfit but don't do enough to justify buying one. anyway if you guy is good it should be fine

im thinking maybe recess the drill bit pins a little to be sure...i think they are to high just incase he is not hot enough???

There's literally factor pin and welds on 14.5" guns being done with a 110 mig in a jig. I don't see why a tig would have any more problem. The first pic, the pin is too high. The second pic is about how I've seen the depth done, although it looks like more chamfer than necessary. 

 

110 volt tig will be just fine.. I use 110 for a lot of small projects at work....

Hey! Did you solve it? I'm pretty sure that standart 120/240 or 110 tig welder is more than enought in this case(article)
