The Lincoln Electric Company has introduced its newest Invertecâ¢ V350-PRO, an advanced process model equipped with pulse MIG welding capability. This power source, like the standard Invertec V350-PRO, is the most powerful inverter in its class. The new Invertec V350-PRO advanced process model features an integrated control panel, which eliminates the cable clutter and pendant confusion found in competitive products. Perfect for automotive work in steel, stainless steel and aluminium, the âConstant Power MIGâ? mode adjusts voltage and current for smooth welding of thin sheet metal. It provides pulse programmes, among others, for Stainless Steel .030â?, .035â? and 045â?; and Nickel .035â? and .045â?.
