TN4000 Portable RF Wood Welder

Part Number
Weld Glue Joints in solid in seconds - The Woodwelder has been used in the woodworking industry for over 30 years. The R.F. generator produces radio waves, via a pair of triode valves. The R.F. is then modified to 27 megahertz and passed down the coaxial cable to the hand gun. The electrodes on the hand gun are placed over the glue line and when the trigger on the hand gun is activated the radio waves pass into the glue line. The Radio waves vibrate the water molecules in the glue, this vibration causes heat and the heat sets off the glue, all within 5 seconds.

  • Radio Frequency Curing has revolutionised gluing techniques in recent years. speeding up assembly processes and increasing production capacity. The Woodwelder works in conjunction with many glues including cross-linked PVA or UF resins which, when subjected to R.F. energy, creates an irreversible bond. The components to be bonded are placed together with a line of glue between them Pressure must be applied using air rams or sash clamps. The welding gun is placed on the timber surface directly over the glue line and the trigger pulled. Bonding takes place in a matter of seconds, as the energy excites the water molecules causing the glue to expand into the pores of the wood whilst evaporating the water. Long glue lines (table tops, panels, mouldings, etc.) are spot welded every 6 to 12 inches along the glue line. The glue not cured by R.F. cures in its own time. The material can be sanded, fielded, or worked soon after welding.
  • The time taken to cure the joint will vary according to the type of timber, the quality of the glue, and the depth of the glue joint. This time would normally vary between 3-10 seconds.
  • Important: For simplicity, most of the illustrations shown here do not show clamping, but workpieces must be clamped prior to using the R.F. gun to obtain the best possible joint.
