Bethlehem The STACKS Bench Burner
The STACKS bench burner was designed specifically to fill the gap between the Alpha burner and the Bravo burner.
After two years of R&D Bethlehem has created the perfect in-between torch for both the beginner and the experienced flame worker! The STACKS includes: the Top Mount “Sharp Flame” surface mix burner, the Bottom Mount “Bravo”-sized surface mix burner, the unique and adjustable STACKS base, the Bethlehem Burners torch cleaning kit, and the Bethlehem Burners “Lifetime Factory Warranty.”
So makes The STACKS special? Versatility!
Each burner is constructed primarily of stainless steel and is equipped with Bethlehem Burners’ one-of-a-kind, stainless steel modular needle valves. Each burner comes with its own B-fitting gas and oxygen hose connections, making each burner a complete and separate torch unto itself.
The Top Mount (STACKS I) is similar to our Alpha torch but produces a sharper flame almost identical to the center fire flame of Bethlehem’s famous PM2D Bench Burner. This “Sharp Flame” has a longer center gas candle, which attracts the outer gas jets and oxygen in towards itself. The longer center candle creates a sharper and slightly more driving flame excellent for fine detail work and fuming.
The Bottom Mount (STACKS II) produces the same flame width and BTU output as the outer fire ring of the Bravo. Unlike the Bravo torch, the STACKS II does not have a center fire. This torch is perfect for medium hollow work, stress-free handling of sensitive colors, mid-sized (2”- 2.25”) solid marbles and gentle, even heating for pulling points.
Both the Top (STACKS I) and Bottom (STACKS II) Mounts work wonderfully with oxygen concentrators! Just like the Alpha and Bravo torches, these burners excel when fueled with a low-pressure system, making them the perfect torches for concentrators.
STACKS I – 8 LPM O2, 8 PSI
STACKS II – 20 LPM O2, 8 PSI

The torch is amazing. My buddy bought it I showed him the ropes. The top flame has an amazing amount of power. Like described. It is like the inner flame of a pm2d without a doubt. It cuts through 12mm rod easily. And can melt down 25mm tube to make a basic spoon pipe.
<br>Bottom flame is big and easily adjustable. Just wish the torch tip was a little longer from the knobs but a little heat won’t hurt.
Amazing Customer Service
I bought the Bethlehem stacks right after it came out and I've been elated with the performance. It is a fantastic beginners torch. This torch enabled me to learn for over a year and a half and get comfortable with the different flame types. It goes from a very large bushy flame to a very tiny pinpoint needle flame. It's got enough flame variety to do whatever you can imagine in your first year and a half to two years on the torch. Bethlehem apparatus company has answered any and all questions I've had regarding my torch. I love my Stacks!!!!
