Abstract: A welding gun spatter shield for insertion in the sleeve opening of a welding gun that prevents contact of spatter with the welding gun components and that prevents the accumulation of spatter on the welding gun. The shield is a body that fits within or over the opening of the welding gun sleeve and fills the opening forming a barrier beyond which the spatter may not pass. The body has a wire feed bore extending axially therethrough to permit the welding wire to extend therethrough. Further, the body includes communication passageways that permit the inert gas to pass through the body in an axial direction. The welding gun spatter shield uses either a friction fit or a retaining ring to maintain the body attached to the sleeve.

Abstract: An apparatus for inserting integrated circuit packages into sockets on a burn-in board includes a plurality of loader heads, one for each column of sockets on the board, for pushing the packages into the sockets; a plurality of support means, one for each loader head, for aligning and supporting the package under the loader head; and a plurality of channels, one for each loader head, for delivering IC packages to the support means. Movement of the loader head in the downward direction clamps the IC package between the loader head and the support means for insertion of the package into the socket.
