Apply simultaneous, uniform 360° wraparound heat to ring shanks, bezels, tubing, and pipe joints without constantly rotating the torch handle. The genuine Miller® SMITH The Little Torch™ Twin Flame Tip Series features dual curved copper arms engineered to direct two opposing needle-point flames onto a single joint at once. Delivering rapid, even heat distribution while preventing cold spots and localized overheating, these tips are fully compatible with all standard fuel gases (Acetylene, Propane, Natural Gas, Hydrogen, MAPP®, and Propylene) across three specialized sizes: #4 (12-1402-04), #5 (12-1402-05), and #6 (12-1402-06).
Why Choose the Miller® SMITH Twin Flame Tip
-
Simultaneous Dual Wraparound Heat: Dual opposing flame orifices encircle round and cylindrical workpieces, cutting soldering time in half and ensuring uniform solder flow around ring shanks, bezels, and tubes.
-
100% Factory Flame Tested: Every genuine Smith tip is flame-tested at the factory to guarantee needle-point stability, consistent gas velocity, and repeatable thermal output.
-
All-Fuel Gas Versatility: Fully operational with Acetylene, Propane, Hydrogen, Natural Gas, MAPP®, and Propylene paired with compressed oxygen.
-
Minimized Thermal Distortion: Concentrated, balanced dual flames focus heat directly at the solder seam, protecting adjacent heat-sensitive gemstones and delicate findings from accidental burns.
-
Solid Copper & Brass Construction: Machined from high-conductivity copper and brass with a precision threaded hex coupling nut for airtight seating on The Little Torch™ handle.
