Thank you, was looking for something like this. I'll look it over well.
To add to my original post, I found this on another website: "Eventually, if the fuel flow is increased beyond the capacity of the burner, the flame will start standing clear of end and it becomes unstable. In open air, the flame will literally blow off the burner."
Sounds like it describes my problem pretty well, which is why I switched to the 0.035" MIG tip, but I got the same results. From what I read, this might mean too much pressure? The regulator is 20 PSI non-adjustable, could that be my issue? I thought the valve would make up for the regulator not being adjustable.
