Flame King torches are built for a wide range of tasks beyond weed control. Common applications include melting snow and ice on driveways and sidewalks, removing parking lot markings and paint, thawing frozen pipes and locks, melting tar and asphalt for repairs, torch-down roofing work, lighting bonfires and charcoal pits, and various woodworking projects. Smaller torch heads in the collection are used for soldering copper pipes, brazing, metalworking, and culinary finishing like searing sous vide proteins or caramelizing sugar.

Flame King weed burner torches are compatible with standard liquid propane cylinders in 5 lb, 10 lb, 20 lb, 30 lb, and 40 lb sizes. For occasional light use, a 10 or 20 lb tank is usually sufficient. For heavy-duty or professional use with a 340,000 BTU or larger torch, a 20 to 40 lb tank provides a longer run time between refills and is more practical for extended sessions. Higher-output torches will deplete smaller tanks faster. Flame King also sells weed burner bundles that pair a torch with an appropriately sized propane tank and carrying backpack or wheeled tank.

Yes, Flame King's higher-output torches (340,000 BTU and up) are widely used for torch-down roofing and waterproofing membrane applications. Before any roofing work, always have a fire extinguisher on site, wear appropriate PPE including goggles and heat-resistant gloves, and follow all applicable NFPA safety guidelines. Review the product safety instructions included with your Flame King torch and comply with local fire codes before performing any torch-down roofing work.
