I have access to a "Home Depot" Lincoln wire feed welder. Its a 220v with no sheilding gas on it. Can I use this for to tack in some new floorpans and maybe fill some small holes in the fenders (I am removing some chrome trim that I do not want to replace)?

Any recommendations on what type of wire works best in these things?

As you may notice, I don't know a whole lot about welding, but am a quick learner.

TIA guys!
