The ProArc WO-15 oscillator is perfect for automated arc manipulation by use of mechanical arc oscillation. It's suitable for MIG/MAG automate processes in heavy fabrication industries. There are four adjustable parameters (oscillation width, oscillation speed, oscillation dwell time on both ends) which controlled by simple control panel. ProArc WO-15 oscillator can work as stand-alone device or be a part of more advanced welding system.
