The Blazer SI-100 Excalibur, multi-purpose, butane torch and hot air soldering kit is a tool kit that provides tools for soldering, hot air blowing and torch flame needs. The torch creates a precise flame emitting from a nozzle head, allowing direct heat application to an object. It is commonly used for detailed purposes such as brazing, plumbing, soldering, heating, jewelry making, and culinary, dental, and lab applications. Tools within the kit are also used for electronic, automotive, woodworking, lapidary, and general maintenance. The SI-100 is a multi-purpose tool kit, providing a self-igniting and cordless soldering iron, hot air blower and refillable butane gas torch. The set includes five, interchangeable tip choices: reflector, hot air blower, knife, one 3.5-millimeter chisel and one 3.0-millimeter diagonal. It also comes with a wrench, sponge, and one tube of 60/40 coiled silver tube of solder. The torch features a child-resistant mechanism, and an instant ignition switch. The torch houses a piezoelectric ignition system, which is based on a pressurized molecular reaction, and requires no electric connection. Piezoelectric energy occurs when the trigger is activated, releasing a small, spring-loaded internal hammer that strikes a crystal, producing a spark and resulting in gas flame ignition. With a maximum flame temperature of 2,500 degrees F, the torch has a 7.0-gram gas capacity, weighs 4.9 ounces and is 9.0 (l) inches. The case measures 10.25 (l) x 4.38 (w) x 1.5 (h) inches.
