Ideal for many applications including heat shrinking, plastic tube bending, soldering, adhesive curing, solder preforms, butt welding, etc. Glo-Rings incorporate quartz encapsulated heating elements which open and close to encircle work pieces with instant radiant heat at temperatures up to 1500°F (815°C). No R.F. interference is generated with the Glo-Rings and they are suitable for use in clean rooms and testing areas. The Glo-Ring is an excellent alternative to heat guns. It uses less electrical energy, does not blow hot air, and is simple to maintain. The triple element bench model has solid state heat controls for shrinking long lengths of heat shrink tubing and other applications. Heating elements open and close around the workpiece either by a switch or by activating the optional electrical foot switch. Adjustable work piece rests keep the work piece central within the heating elements. One, two, or all three element holders may be utilized at any time, and all four element sizes are interchangeable in the holders. Note: Guards & elements sold separate.
