Available from Brookhuis, the Tregarne Woodwelder is a radio frequency (R.F.) generator that produces radio waves via a pair of triode valves. In 15 seconds or less, the R.F. is modified to 27 megahertz and passed down the coaxial cable to the hand gun, which is placed across the glue line to allow the radio waves to pass into it. The radio waves vibrate the water molecules in the glue to generate heat, which sets off the glue. Each Tregarne Woodwelder comes with a starter pack of glue and a set of standard and offset electrodes. Also available for purchase are inside miter electrodes, outside miter electrodes, and blank electrodes which can be cut to custom profile.
