This gas torch is a straightforward tool with a wide range of applications around the house, outdoors, or in cooking, including heating, kindling, soldering, and so on. To get started, simply connect the torch to the gas cylinder with a collet and pull the trigger in the front. This creates a spark at the edge of the nozzle to achieve instant ignition. The trigger provides some resistance in order to avoid accidental ignition. Sensitive control knob enables smooth adjustment of the flame size and temperature (up to 2372°F). A collet-body gas cylinder directly connects to the torch jack and can be used as a handle. The GB-0020 torch has modest dimensions of 170x50x70 mm (6.7x2x2.8 inches) and weighs only 0.34 Lb.
