Solid state generators adjust the output impedance to respond quickly and with accuracy to changing loads during the welding cycle. These changes over time are monitored and recorded in order to ensure a perfect weld in each cycle, resulting in a better quality weld, with a lower power output.

The solid state high-frequency generators made by ZEMAT, fitted with the Autotuning™ system, feature precise control of the output power, which guarantees perfect welding in every cycle. By using ultra-fast reflected power control, the system’s semiconductors can be protected. These generators are fitted with an automatic tuning system as well as a puncture protection system to guarantee the safety of their use.

Furthermore, solid-state generators have low power consumption and real-time output control. These generators are compliant with CE, FCC, EMC & UL standards, confirming their high quality. Optionally, we can provide the generators with a heated tool/electrode plate to accelerate the high-frequency welding process or produce a better welding environment for the materials.

With the use of a precision servo-controlled linear motor to move the electrode, positioners, stops or spacers can be eliminated. This produces a fully repeatable stroke position for each welding cycle. We have the ability to work with full control of position and pressure – for example, if we have materials of the same thickness, we can control bothposition and downward pressure, and if we are working with materials of different thicknesses, we control the pressure, ensuring the repeatability of each weld. Being able to produce customised pressure characteristics is dependent on the requirements of the application. E.g.: a different pressure/position at the start of the welding cycle – a different one during cooling/extraction.
