WebMMA and TIG processes can be either alternating current (AC) or direct current (DC) whilst MIG is usually only operated with DC. As arc processes need a large current (up to 500 A) but at a relatively low arc voltage (10 to 40V),the high voltage mains supply (230 or 400V) must be reduced. In its basic form, the power source for generating AC ... WebCurrent flowing through axle bearings damages the bearings and reduces their service lifetime.
