Ribbon burner question in Tools and Tool Making Posted January 12 What size are the gas jets in your "Venturi" burners? Can you change them fairly readily? If you are using mig tips as gas jets, try a smaller size. It may seem counter-intuitive at first, but there is a very high probability it will increase your temperature and dramatically reduce the Dragons Breath. I would aim for about half the area at first; 0.707 times the diameter and see where you need to go from there. Ideally, you want to get to, or just above, the maximum (welding) temperature you'll ever want with the choke slides fully open. Then you can reduce airflow with the chokes to get cooler, more reducing, temperatures for forging. Note that mig tips are sized by the wire diameter they are intended for welding with and the hole is typically about .006" or .015mm bigger than the nominal size. I'd certainly spend a couple of hours playing with the burners you have before embarking on a ribbon burner build. Even if you don't get them working to your satisfaction, you'll become familiar with the effect that varying the mixture has on the flame temperature.
