The Flame King FK8500CGA Advance Torch Max produces a high-intensity ULTRA SWIRL FLAME perfect for metal working, brazing copper and steel, large diameter soldering, woodworking, lighting grills, thawing frozen pipes and locks, searing meat, caramelizing sugar, and any general DIY heat applications. It is pressure-regulated for consistent performance when tilted or inverted. Its continuous flame lock button keeps the torch lit for finger-free use. Very easy and simple to use with the instant on/off ignition that automatically ignites the flame while the flame adjustment knob easily adjusts the flame size. Its ergonomically designed grip provides comfortable and controlled use. The stainless steel burn tube, cast aluminum body, and brass burn tip were constructed for safety, durability, and performance. Secure CGA600 connection fits perfectly with the Flame King's 1/4LB and 1LB Propane Cylinders (sold separately). This torch also works with other popular fuel gases - standard 1lb Propane cylinders, MAPP, and MAP-PRO
