AVC (Arc Voltage Control) is a system that can be integrated into AVP welding machines or custom-built to customer specifications.

Currently, we exclusively support Fronius and Lorch welding power sources.

The main advantage of the AVC system is achieving higher weld quality – the system automatically adjusts the torch height based on real-time welding data (primarily arc voltage). Using AVC control enables significantly higher welding speeds than standard operations. The torch is automatically adjusted along the vertical axis via a servo motor according to the set parameters.

It is most commonly used in TIG and plasma welding processes, but can also control MIG/MAG welding.
