The high frequency welder MAGNA is designed for welding large objects and allows 360° access to the working space. MAGNA is available in three versions – as a separate, suspended welding head or a large-format welding machine.
The HF generator, air cylinders and electric power supply unit is fully integrated within the suspended weld head, creating an open space for a lightweight work table of various sizes and shapes (rectangular or round). It can be installed right above the floor to allow for easy handling of heavy and high volume dimensional fabrics. The size of the welding/work table are custom-made in accordance with the HF welding electrode length.
Magna S machine is equipped with a hand operated rotating turret with 180+ deg. rotation function. They allow for open and easy access to the work table and the welding head from any direction and are used in the production process of large technical textile structures, high speed doors, fishery tanks, tents, tensile and membrane structures, advertising billboards, oil-booms, water cisterns, pool-liners, etc.
The welding head moves along the X-axis with multipoint pressure on the electrode. A special control software, HF weld head driven on X-linear robotic beam, 360º access to workspace allows to make unlimited large platen or curved, angular or repeated parallel straight weld joints.
25kW Hi-Q Gen5 RF generator is capable of providing stable output power for seams up to 1000cm2 (155 sq inch). The dimensions of the welding/work table are custom-made in accordance with the welding electrode length. The machine allow open and easy access to the work table and the welding head.
It is equipped with a true 360º rotation function. The dimensions of the welding/work table are custom-made in accordance with the welding electrode length.
The MAGNA 3D Gantry machines allow open and easy access to the work table and the welding head and are used in the production process of high speed doors, tents, tensile and membrane structures, advertising billboards, oil-booms, water cisterns, pool-liners, portable satellite dishes, etc.
High frequency welders manufactured by Zemat Technology Group are designed and built in accordance with current European requirements for machine safety and energy efficiency. The machine design incorporates technical solutions that enhance welding process stability, reduce energy losses, and increase production repeatability.
HF Smart Control™ is a set of structural and electronic solutions implemented in high frequency welders, including:
The HF/RH welders use high frequency generators with microprocessor-based power control, enabling precise adjustment of energy to the process parameters. The system continuously monitors operating conditions and dynamically regulates power in real time. As a result, energy consumption can be reduced compared to heat sealing technologies and many impulse-based systems. The actual level of savings depends on the material, application, and process settings.
The ATS ensures precise impedance matching and automatic generator tuning during machine operation. This stabilizes the welding process, reduces the risk of instability, and minimizes the possibility of arcing. Fast reflected power control protects HF circuit components and improves weld repeatability.
Modern HF generators achieve energy efficiency levels of approximately 70–90%, depending on configuration and operating conditions. Band-pass filters reduce harmonic distortion, while lower thermal losses decrease heating of machine components. This results in stable operation and extended service life of key components.
