Original DEPTA NX is the smallest machine in a large family of ZEMAT TG HF welders. This universal high frequency welder is robustly constructed and designed for accuracy and long life.
DEPTA NX is newer model of one of the most popular machines: DEPTA
DEPTA NX is a universal, high frequency welding machine and can be used in various industries. For seaming type work, a small tool mount is recommended to give good visibility and access to the work area. For other applications a large mount can be supplied giving rigid support over a wide tool area. Facilities are also available to increase the throat space, where excess materials have to be positioned behind the tooling.
DEPTA NX is widely used in medical, automotive and clothing industries for welding small add-on parts, like tubing, air and fluid valves, hooks, grommets, plates, etc. DEPTA NXhave a high frequency power output from 0.5 to 4kW. The machine is a perfect tool for auxiliary production where precision, manual approach, durability and strength are the keys.

Full diagnostic testing and certification of the local factory EMC/EMS parameters according to the latest guidelines required by the CE & UL standards. We have our own ISO 17025 certified production control and EMC laboratory providing validation of each required process parameters and the whole technological production cycle.
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.
