Main Features

Plain Text Display

The TPS 500i features an intuitive plain text display that shows all welding parameters in clear language. By analyzing user interaction data, Fronius optimized the panel layout, color scheme, brightness, and button feedback. Graphics and text work together to make operation faster and simpler – even when wearing heavy welding gloves.

FSC Interface (Fast System Connector)

The FSC interface is the central connection point between the welding machine and various welding peripherals. It allows tool‑less, quick connection of torch and feeder lines, ensuring stable current transmission and significantly reducing downtime during maintenance or replacement of wear parts.

Plug & Weld Functionality

Every component of the TPS 500i system can be installed manually. After connection, the system automatically identifies the attached components and alerts the user if any incompatible part is detected. This plug‑and‑weld capability prevents incorrect setup, guarantees system integrity, and simplifies installation.

SpeedNet Communication

The integrated SpeedNet data bus operates at up to 100 Mbit/s, enabling real‑time, high‑speed communication between all welding system components. This ensures precise process control, instantaneous parameter adjustments, and continuous monitoring of system status, resulting in superior weld quality and reliability.
