The Bernzomatic Hose Torch is made for high-heat soldering and brazing in hard-to-reach spaces. A hose and slender body provide maximum accessibility, while an adjustable swirl flame provides hot, efficient heat and fast soldering times. An instant on/off trigger makes one-hand ignition quick and easy, while a continuous run-lock button allows for extended use.
