Fronius welding guns for the DeltaSpot process are made from high-strength aluminium materials, allowing them to withstand the high demands and stresses placed on them during aluminium spot welding in particular. These welding guns were developed in cooperation with customers in the automotive industry, making them ideally suited to the requirements of this industry and guaranteeing maximum welding quality. The base bodies of the spot welding guns have a modular design, meaning that all guns can be supplied in a left-handed or right-handed version. The welding arms are individually adapted to the welding task. There are three product variants to choose from depending on the application or welding task: the X-gun and the C-gun for use on a robot, and a stationary system for manual applications.
