Well got another toy. I had been looking at the Hobart Holder 140 welders. Well I went to the store as they had a sale going. I ended up getting a Holder 190 for a little more than what the 140 would have cost. The 190 can do 5/16. I probably won't do anything more than 1/4 but that would be pushing the 140 to the limit where with the 190 it will go better.
I will start with the flux core but being I am a homebrewer I have a 10# and 20# tanks of CO2 for my keg systems. I need to get the adapter though so I can connect it to the regulator.
