TurboTorch has developed a new series of hand torches that also feature Extreme Swirl Technology. The new Extreme series generates more heat than other hand torches for faster brazing times and less gas consumption. All Extreme series hand torches and tips feature TurboTorch swirl combustion. Higher heat levels, in a short amount of time, enable the pros to quickly complete the job. The TX 503 series is a "cooler" torch, making it ideal for general plumbing jobs. It features convenient self-lighting triggers, and quick disconnect couplings between handle and tips. Processes: Air/MAPP and Propane.
