#1 - Are you sure your gas bottle is on and it's not down to the bottom in pressure?? Brand new bottle.
#2 - Give us some data -- tube gauge - and your welder settings including GAS flow rate 16ga mild steel, setting 3 out of 5 on a 110v Hobart which is what the recommended setting is, wire speed only fast enough to have a continuous feed which is a little below what's recommended. Gas is at 25 for flow. I'm doing this in the garage so wind shouldn't be a factor.
#3 - Are you cleaning the INSIDE of the tubing? Yes, inside and outside wiped down with denatured alcohol.
#4 - what wire are you using - as in specs and supplier. 0.030 solid steel Lincoln wire. Going to pick up some 0.024 wire today just for the hell of it.
#5 - are you snipping the end of the wire at a 45* angle after or just prior to welding so you're not welding with a ball and smoke on the end of the wire.Nope. Didn't know this was necessary. I'll try it out this evening.

Answers are in blue. By wetted, do you mean the welds don't appear to be melted into the steel and are more on top of the metal?
Thanks Greg.
