Features

Improved working environment is created during welding. Welders are not exposed to open flame, explosive gases and hot elements associated with fuel gas heating and resistance heating.

Easy set-up is achieved using flexible heating cables combined with user-friendly insulation blankets.

On-board temperature control provides for manual or temperature based programming in a simple-to-learn operator interface.

Uniform heating is maintained along and through the heat zone by using induction to heat within the material. The surface of the part is not marred by localized conducted heat at higher than specified temperatures.

Time-to-temperature is faster than conventional processes due to the method of applying heat, reducing cycle time
