Red Dragon® Liquid Torch Kits are designed for those applications where continuous use is required. These kits are ideally suited for colder climates where operations at sub-zero temperatures are required. The self-vaporizing torches are excellent for road repair, surface drying, preheating castings for welding, weed burning, melting snow and ice and many other jobs. Two kits to choose from. All Red Dragon Torches are made in the U.S.A. Red Dragon® Liquid Torch Kits require a liquid withdrawal propane cylinder.
