The newly developed PS-6A automatic stud welding gun guarantees a maximum of technical performance advantages for the production of high-quality stud welds combined with a simple and practically-oriented operation. The studs can either be fed semi-automatically by hand or fully automatically from the UVR-300 or UVR-400 universal feeder via the feed chute into the stud holder. The PS-6A automatic stud welding gun is of a particularly sturdy and durable design and is above all suited for professional continuous operation.
