ABSTRACT:
A base is mounted on a welding machine and has slide rails. Each rail has paired flat top sides angularly converging upwardly toward one another. A table has slide channels also each having paired flat sides angularly converging upwardly toward one another at angles substantially equal to that of the rails. The table channels rest on the rails with their flat sides in sliding relationship to the flat sides of the rails. When welding forces are applied to the table, the flat sides of the rails and channels jam or wedge into substantially solid electrical contact at their interface due to their angulation. A shield is attached to the end of the table and covers the rails in their exposed projection beyond the table. In a table having two welding locations, a shield is attached at both ends of the table. The shields protect the rails against welding spatter, dust, etc., to keep the rails clean to insure maximum electrical contact. The sliding table allows a workman to load and unload workpieces outside of the welding area which substantially reduces the likelihood of accidental injury.
