Execute high-efficiency precious metal casting melts, large-component brazing, and uniform thermal annealing with authentic Miller® SMITH 6-Inch Multi-Port Heating Tips. Designed as precision heavy-duty melting nozzles for the Miller® Smith Little Torch™ handle, these extended 6-inch (153mm) copper tips produce a broad, concentrated rosebud heat envelope. Capable of melting up to 3 ounces (approx. 85 grams) of solid gold or silver, they are available in two specialized gas-mixing configurations: the 4-hole multi-fuel tip (#13-662) for Acetylene, Hydrogen, and MAPP®, and the 6-hole recessed tip (#13717) engineered specifically for Propane and Natural Gas.
Key Features & Benefits
-
High-Capacity 3 oz (85g) Precious Metal Melting: Generates substantial thermal energy (up to 10,800 BTU/hr with Hydrogen) to melt up to three ounces of gold, silver, or bronze scrap and casting grain in standard melting dishes.
-
Extended 6-Inch (153mm) Reach for Working Safety: Keeps the technician’s hands and torch handle at a safe distance from high radiant crucible heat, providing clear line-of-sight visibility over the melt.
-
Multi-Orifice Rosebud Flame Pattern: Distributes heat evenly across wide surface areas, preventing hot-spot metal oxidation and metal vaporizing common with single-orifice micro tips.
-
Dedicated Fuel Gas Optimizations:
-
#13-662 (4-Hole): Optimized for high-velocity fuels including Acetylene, Hydrogen, MAPP®, and Propylene.
-
#13717 (6-Hole Recessed): Features a specialized recessed nozzle cup designed to stabilize low-velocity Propane and Natural Gas flames with Oxygen.
