The Visar 650 and Pegasar 500 accu stud welding equipment from the Quasar model range is distinguished by a particularly low weight. The Visar 650 facilitates stud welding with a 230-volt instead of 400-volt power supply and the Pegasar 500 accu mobile stud welding without an external power supply. Both devices feature internal cooling systems, making them dust-proof from the outside. The bumpers fashioned from shock-resistant polymer ensure impact protection.
