Im Using .035 mig tip used some gas tape to tighten up the fit . Still need some set screws to hold directly down the tube .1.5 to .75 inch bell on top bottom is .75 to 1 inch i left the threads in the bottom or flame side. Should I remove these? And is .035 enough or should I open it up to a larger orifice? The flame seems better with the tape but still id like better. Please advise oh great burner gods! P.S. new photos attached.
