This is a relatively simple and low-cost burner that performs in an exceptional way.
The needle valve gives you a high degree of control over the fuel flow and will burn on high heat for 4-5 hours on a small 20 lb BBQ tank. If you turn it down between heats you can get up to 8 hours on that same tank!
The 1 1/4” x 3/4” reducer lets in plenty of oxygen for high heat.
Many full-time smiths use this burner for all of their forging needs. Robust design keeps this burner functioning for many years. But just in case, all the parts are easily replaceable. Great bang for your buck!
