The Black Widow is a 4 inlet torch. The Widow base is something entirely unique. It can be adjusted vertically to accommodate the standing artist or a larger piece of artwork. The head of the torch is also adjustable in a front-to-back motion (almost straight up or down) and turns 360°. The Widow is the perfect torch for any Borosilicate worker as well as the soft glass bead maker and sculpture master. Fuel consumption based on standard usage is approximately 80 CFH (cubic foot per hour) of propane and 448 CFH of oxygen. This burner may be used with oxygen and either natural gas, propane, or even hydrogen. The recommended operating pressures are 3- 5 PSI (Pounds per Square Inch) for fuel gas and 10-25 PSI for oxygen, based upon your requirements. The Black Widow has become somewhat of a testing ground for Carlisle based upon requests from the user community. This torch has been configured with premixed and surface mixed center fires with mixed success. The overall favorite though seems to be the all surface mixed model. But most artists want and need the tiny laser-like flame generated by our pre-mixed #3 center fire.
