Mikey98118 Posted December 18, 2018 Share Posted December 18, 2018 No way! You have a heavily reducing flame, which is also a lifting flame. A reducing flame is fuel rich; it won't get anywhere near as hot as a neutral flame, but more importantly, it will produce lots of carbon monoxide. Another way to think of reducing flames is as "air starved". Your burner isn't inducing enough atmosphere. A lifting flame, as the name implies, partially or completely lifts off the burner's end; these are unstable, and can blow out at any time. The common cause behind an unstable flame is that it CAN'T stay centered on the burner. At one or more points your burner may not be axially true. The other way flames get pushed off center is for the gas orifice to be out of parallel or off center with the burner's axis; this is the more likely scenario, because your lifting flame is also pulsing heavily. A lifting flame from misaligned pipe parts tends to also be off-side, but isn't all that likely to pulse much; or it would be snuffed out. So, lets forget about forge photos for now, and give us a video of your burner running out in the open air. Let's also have a close up of the burner, so we can see any obvious problems.

Thank you for your response I played with it some more and got a better burn but still do not know if it's right. It roars if there is nothing choking the air off. I can fully choke the air off and it's still burns good but doesn't roar like it does without it. I am going to change the 3/4" pipe nipple from 5" to 6" I think maybe or 7" I'm not sure I didn't realize the one I originally bought was a 5". As far as I can tell th orifice is centered in the pipe I have 4 offset bolts that I adjusted to get it centered. I'm using a .25 mig tip from lowes as my orifice. and I think I'm running around 10psi on pressure waiting on a guage to come in to know for sure.

Mikey98118 Posted December 19, 2018 Share Posted December 19, 2018 Well dang, Matt; what an improvement! Ya gonna stop there, or go for even more? If you want more than reduce the orifice diameter of your gas jet a few thousandths of an inch. We will all be watching... Quote Link to comment Share on other sites More sharing options...
Matt Watson Posted December 19, 2018 Author Share Posted December 19, 2018 Thank you sir! If I can find a smaller mig tip I will try it and see but at this point I stuck where I'm at except adjusting air and psi Quote Link to comment Share on other sites More sharing options...
