Software notes	The machine's operating system features advanced synergic control, significantly streamlining the setup of operating parameters. The SYNSTAR 400 TS comes standard with over sixty pre-loaded synergic programs, carefully optimized for various alloys, thicknesses, and wire diameters (iron, aluminum, stainless steel, and flux-cored wire). Users can save their custom settings in the system's memory for quick retrieval during repetitive tasks. The color LCD interface provides a clear and intuitive real-time readout of all welding values. Furthermore, the welder's base software is highly expandable: sophisticated features such as pulsed and double-pulsed welding are available via dedicated software upgrade packages. This modular approach allows the operator to adapt the power source to new and more complex welding requirements over time.	The SYNSTAR 330 TS features a proprietary, microprocessor-controlled interface managed via a built-in touchscreen display. This system provides access to over 70 pre-loaded synergic curves, optimizing welding parameters based on material type, wire diameter, and gas mixture. Operators can easily update the machine's firmware and upload new specialized synergic programs via a standard USB port, ensuring long-term compatibility with new filler materials. The software allows users to save and recall custom welding jobs for repeatable accuracy across different shifts. It operates entirely offline, requiring no cloud connectivity or subscription, thereby ensuring full functionality and data security in isolated industrial facilities.
