ECO Friendly High Frequency Technology

ZEMAT TG High Frequency welding machines are designed and built to very strict European Environmental and Safety regulations and have custom design solutions for weld and safety control.

ECO-Friendly HF Technology incorporated in the High Frequency machines contains:

  • Energy efficient ECO HF generators with microprocessor control of output power
  • 90% less power consumption than with traditional heat powered welding systems
  • Dynamic High-performance HF impedance matching
  • RF power output efficiency at 70-90%
  • Ultra-fast reflected power control
  • Dynamic Auto Tuning and Arc protection unit
  • Harmonic distortions eliminated by frequency band filters
  • Low power consumption and real time power output recognition
  • Very limited heat dissipation preventing overheating

HF machine build structure

  • Fully recyclable (100%) rolled Steel and Aluminum frames
  • Environmentally friendly components in electric and pneumatic circuitry
  • Non-toxic coatings and surfaces

ZTG RF Autotuning System™ – automatic control of energy saving output HF power flow based on Zemat TG custom HF power matching algorithms.  An independent HF Auto-Tuning system provides feedback control to maintain minimum reflected power for all RF generator modes of operation. The RFTune™ series of impedance matching systems is optimized to provide fast, reliable and robust matching capability under the most severe process conditions.

ZTG WCSTM Weld Check System –  the algorithms provide a continuous process monitoring system – OFFSET min / max for process parameters (weld time, current value, electrode pressure) for efficient work load and energy saving capability. 

 ZTG SafeDOWN™ – tooling bar press protection system for operator safety and ease of operating and positioning of welded material combined with our Pressure Logic System PLSTMintelligent down-stroke pressure setting for thick and heavy fabrics’ welding cycles.

In terms of EMC safety regulations, our company has a Certified EMF laboratory, and each machine has not only CE mark – which is included with the technical documentation we provided to you — but it’s also fully tested before it leaves our factory:
