Key Features & Benefits
-
Cutting & Welding Capabilities
Capable of cutting steel up to 6 inches thick and welding up to ⅜ inch in a single pass.
Heating capacity peaks at approximately 40,125 BTU/hr, making it a solid choice for preheating, brazing, or annealing.

In‑Tip Gas Mixing for Efficiency & Safety
Each cutting tip features precision in‑tip mixing, carefully pre‑mixing acetylene and oxygen inside the tip to reduce flashback risk and improve flame stability.
-
Slip‑In Tip Design + Graf‑Tite® Soft Seats
Tips are simple to change — after the initial wrench tightening, future swaps can be done by hand. The Graf‑Tite® soft seat material protects against nicks and wear, enhancing tip life.
