Venture to the dark side gentlemen. I've been two timing ya'll. I am a Stovebolter at heart but also have a 1953 F100 and toy around on the Ford Truck forums as well as here. I guess I just like old trucks period! Here's a really good article on welding....

A larger diameter wire is going to throw more juice into the weld area. You didn't mention if you're using a flux core or shielded gas either. Hope this helps...if you're brave enough to visit the site. Lol.
