Thanks

Oh, in those pictures, I have run my wire brush over the welds to clean them a little before taking a picture of them.

Okay --- those are "dirty" MIG welds --- so something is going on. There's too much splatter and crap around the series of tack welds you've laid down and they don't look to be "wetted" out much either.

#1 - Are you sure your gas bottle is on and it's not down to the bottom in pressure??

#2 - Give us some data -- tube gauge - and your welder settings including GAS flow rate

#3 - Are you cleaning the INSIDE of the tubing?

#4 - what wire are you using - as in specs and supplier.

#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.
