Unique design

OPTIMA high frequency welder worktable is equipped with special high-precision rotary indexing gear controlled by frequency inverter. The machine operation is based on step by step technology with possibility of multiple welds in one cycle.

With the use of touch screen HMI and programmable PLC, the operator can easily input multiple weld/seam recipes. OPTIMA series machines have production power outputs from 10kW to 20kW for multi-cavity production loads and specialized products.

Automatic weld cycles, optional preheated or cooled weld platen, pneumatic or hydraulic weld head drive, electronic motion and weld cycle counter make this machine a perfect tool for a high-end production facility where precision, durability and strength are the key.

Why is our technology unique?

WCS™ Weld Check System
Verifying and signaling the HF/RF weld preset parameters / end cycle process. Collects all data pertaining to each weld cycle for remote diagnosis of any issues or problems with machine setup or power output.
QuickGrip™ System
System for quick and easy replacement of electrodes. The electrodes are attached with pneumatic clamps activated from the control panel.
AntiFlash™ System
Ultra-fast Solid-State ARC sensor & full output overload protection.
ZTG iCOM™ System
Built-in VPN client and VNC server making up the internet interface allowing remote control of machine parameters, weld cycle and diagnostics or software upgrade.
Safety guards
Special guards with safety limit switches designed for protection against electromagnetic radiation (compliance with EN and EMC standards).


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.
