A spool gun is used in welding to feed soft or delicate wire, such as aluminum, directly from a small spool mounted on the gun itself. This prevents the wire from kinking or tangling, which can happen if it is pushed through a long cable from a remote feeder. Spool guns are especially helpful for welding aluminum and other wires that are difficult to feed over long distances.
