This Pro-quality Jeweler's Torch is small enough to maneuver into areas where full-sized torches just will not fit, so it is ideal for soldering or brazing small parts. Great for applying heat to stuck nuts and bolts without damaging surrounding area. The Acetylene Torch Kit has five interchangeable copper tips (orifice sizes from.003in. to.029in.) which apply heat up to 6,300 degrees fahrenheit. It includes six feet of color-coded hose, standard B fittings for all industrial cylinder regulators. Gas welding goggles are recommended.
