Jason @ MacTalis Ironworks Posted April 2, 2011 Share Posted April 2, 2011 First off, I am wondering what effect orifice size have on a burner? I have a 3/4" Sidearm and am currently using a .045 mig tip for an orifice, wondering if dropping it to a .035 would be beneficial... Second, I am having a little trouble with sputtering and huffing with the burner in the forge. It burns textbook perfect when out of the forge. What would be causing this and how would I rectify it. It seems to be worst when the forge is cold. Quote Link to comment Share on other sites More sharing options...
Dodge Posted April 2, 2011 Share Posted April 2, 2011 You could be burning rich causing the huffing. The smaller mig tip is worth a try. That's the beauty of mig tips. Like changing jets in a carb. Generally, a .045 would be too big for a 3/4" burner pipe. You can only shove so much fuel/air mix through a give size pipe and in my experience, a # 57 (.043") or smaller works best in my area Eastern Nebraska). Ground elevation comes into the formula at some point. If you are at a higher elevation such as in the mountains it could need even smaller jets to compensate for the thinner air.

Jason @ MacTalis Ironworks Posted April 3, 2011 Author Share Posted April 3, 2011 That was about what I was thinking, was just looking for a second opinion...
