The OSC 8 pendulum oscillator is designed to oscillate MIG/MAG torches with a diameter of 16–22 mm (5/8–7/8″). The oscillator is installed onto a 22 mm (7/8″) diameter rod and connected to a welding device. It can be controlled manually or by using an external START-STOP switch. Using optional freestanding support allows the welding of rotating pipes or moving plates. An optional power supply allows connecting the oscillator to a 230 V or 115V power source.
