Köco stud welding machines are high-performance production equipment that can significantly reduce the cost of joining components when compared to other methods. Threadless and threaded pins, studs with head, anchors etc. with a diameter of 3 to 25 mm can be quickly and high quality welded to sheet metal, pipes, profiles. This eliminates many additional preparatory operations such as drilling, threading, manual welding or tightening.
