Mark the Locations for Drilling the Mounting Holes. Mark the location for the first hole. Use a pipe tape to find and mark the location of the opposite side hole. MIG-Wire Welding . MIG WELDING. MIG welding was developed in the 1940's and 60 years later the general principle is still very much the same. MIG welding uses an arc of electricity to create a short circuit between a continuously fed anode (+ the wire-fed welding gun) and a cathode ( - the metal being welded). .
