The Flame King FK4500CGA Advance Performance Torch produces a high-intensity ULTRA SWIRL FLAME perfect for metal works, 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 and extinguishes when finished. 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 1/4 lbs. and 1 lbs. Propane Cylinders (sold separately). This torch also works with other popular fuel gases - standard 1 lbs. Propane cylinders, MAPP and MAP-PRO.
