Seeking advice on how to extract broken lug bolts

I'm gonna check the two welding supply places near my shop. If they have those rods, great, but I really need to get this done asap. Too much work to do that's requiring the lift.

The holes are 7/16", and aiming a mig gun that far down a hole and getting it precise just ain't gonna happen for me. If I were to attempt the tig process, I'd have to extend the tungsten quite a bit, and then squeeze filler rod in there without touching the tungsten would be damn near impossible (at least for me). I'll keep you all posted on how it goes.
