Solder, anneal, and melt small amounts of precious metal at the bench on one fuel cylinder, with no oxygen bottle to buy or maintain. 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. Acetylene burns hotter and denser than propane, so the flame is smaller and more intense for faster small-scale soldering.
Swapping tips takes the torch from delicate bench work up to melting 3–4 oz of precious metal without changing the gauge setting, because the regulator runs at 13–14 PSI for all tips. The kit ships with the torch body, a 12 foot hose with standard B fittings, a size 00 very fine tip, and an acetylene B-tank regulator. No oxygen bottle is required.
Runs on acetylene with atmospheric air and needs no oxygen cylinder. Connects to a standard acetylene B tank, which is not included, through USA standard B (9/16"-18) hose fittings.
What you get:
Tank not included. This kit uses a standard acetylene B tank.
