Pat,

When you don't purge the tubes how do they look inside? Are you butt welding pieces without a filler rod? Tomorrow I'll play with a couple scrap pieces without gas and see how it turns out.

Charlie,

You are right. I can use my MIG bottle and was going that route verses buying a third bottle. But i really wanted to use the same bottle in case I'm using my MIG at the same time. I jump around a lot....A.D.D. LOLs.

My buddies gave me a hard time about having two bottles but I like the idea of knowing that if one runs out I still have one to fall back on so I don't have to stop and have it refilled. More convenient.
