The Lincoln Electric Co. (www.lincolnelectric.com) introduced a multi-process, inverter-based welding power source with a welding power output range of 5 to 570 amps. The Invertec V450-PRO is intended for heavy fabrication, such as performed by shops that weld with 0.0624-in. or larger diameter welding wire electrodes and that provide arc gouging repair with 0.375-in. carbon. The company says the machine handles stick, TIG, MIG, flux-cored and gouging processes in standard factory configuration, and has pulsing capability with the advanced process panel kit.
