Wise meets the welder FOUR ARC TOOLS EVERY WELDER SHOULD HAVE The shift in development of welding power sources toward more digital weld distortion due to the 10–25% low- devices opens new approaches to welding process development. Nowa- er heat input used compared to standard days, the control of welding machines is based more and more on software components. A digital system improves the reaction times of welding MIG/MAG welding. WisePenetration™ has been designed to reduce poor fusion and incomplete pen- parameters.
