The Smith Silversmith Acetylene atmospheric air torch is a classroom favorite—safe, economical, and easy to light and adjust for a perfect flame every time. Because acetylene burns hotter and denser than propane, you get a smaller, more intense flame for faster small-scale soldering compared to propane EZ torches or butane hand torches. Swap tips to jump from delicate bench work to melting 3–4 oz of precious metal—without changing the gauge setting (run regulator at 13–14 PSI for all tips). No oxygen bottle required.
