The FRONIUS iWAVE 300i AC/DC TIG Powersource is a high-precision welding machine designed for professional welders requiring maximum control and quality across a variety of materials. It supports both AC and DC welding processes, making it suitable for diverse TIG welding applications.

This TIG welder features targeted heat input and an improved ignition function, delivering precise arc control and significantly reduced ignition delays. The intuitive operating elements and graphical dynamic menu navigation, available in over 30 languages, enable straightforward adjustments and efficient workflow.

Key functional benefits include Cycle TIG mode for enhanced control of the weld pool and heat input, allowing reliable welding of thin materials with short welding times. The automatic cap-shaping function forms electrode caps in just 2 seconds based on the set electrode diameter, saving setup time.

The iWAVE 300i also offers a tacking mode that oscillates the weld pool using pulse currents, reducing tacking time by up to 50% and minimizing temper colors on tacking points. Its Sync Mode facilitates synchronous, double-sided TIG welding with alternating current by automatically harmonizing both arcs, enabling two welders to work in perfect synchronization.

Welders can select or combine AC waveforms tailored to specific welding requirements, ensuring the right arc characteristics for each task. Additionally, the automatic gas post-flow protects the tungsten electrode and weld from oxidation by calculating gas shielding duration based on welding current and electrode diameter.
