The FRONIUS TransSteel 3500 Power Source is a compact multiprocess welding system designed for structural steel fabricators requiring reliable and stable welding performance. It offers a robust 350A output with a 40% duty cycle, suitable for various welding applications.

This power source features digital welding-process control and an automatic reduction of wire feed speed to prevent arc extinction, ensuring consistent weld quality. It supports both gas and water-cooled torches, enhancing versatility for different operational environments.

Additional functionalities include a 4-roller drive system, synergic programmes for optimized welding parameters, and automatic burn-back control. The unit also provides a digital display for welding amperage, voltage, material thickness, and wire feed speed, facilitating precise adjustments.

Ergonomic features such as continuous power adjustment directly from the torch via Up/Down controls and five fast job memory keys (in the synergic version) improve workflow efficiency. The system is equipped with a dust filter, temperature-controlled fan, earth leakage monitoring, and remote control capability, meeting safety and operational standards including S mark, CE mark, and C Tick certifications.
