AC/DC capability is key because DC is required for welding most steels, while AC is necessary for welding aluminum and magnesium. Having both options in one machine allows for maximum material versatility. The Precision TIG 375 and Aspect 375 AC/DC both offer AC/DC welding, making them ideal for fabricators who work with a variety of metals. Since not all used tig welders for sale offer both capabilities, having a selection ensures buyers can find a machine that fits their metalworking needs.
