Spiral Fin Tube High Frequency Welders - Thermatool Corp.

Spiral Fin Tube HF Welders

Produce high quality Spiral Fin Tube efficiently with our Solid State Spiral Fin Tube Welders.

Achieve these excellent benefits with a Spiral Fin Tube Welder:

  • Smoother output and improved weld quality
  • Weld more alloys more efficiently
  • Run higher RPM’s at lower kilowatt voltage
  • Less arcing and sparking with improved contact life
  • Use less power and water
  • Improved safety and less floor space
  • Reduction in scrap

  • Power Efficiency. Increased output efficiency, resulting in power cost savings
  • Reliable. Elimination of expensive finite life components such as the vacuum tube, RF output transformer and tank capacitors adds to increased reliability and up-time, and a significant reduction in maintenance costs.
  • Improve DC Ripple. Smoother output wave shape compared to to a vacuum tube welder. Less welder spatter and forge tooling wear.
  • Safety. Solid State welders operate at much lower voltages than vacuum tube units – not exceeding 1200 volts at full power assuring added safety operators and maintenance personnel.
  • Floor Space. Solid State welders are extremely compact, occupying minimal space. The power supply can be placed up to 1,000 feet away from the mill.
  • Improved contact wear. Due to less arcing.
  • Reduction in scrap. Due to improved automatic Speed Power Control, reducing unwelded fin areas when stopping and starting.
