ABSTRACT:
A welding bench has a base plate supporting a substantially vertical outer casing with a rectangular or square cross-section. Supported in the outer casing is an inner casing projecting out of the outer casing and vertically movable by means of a variable length device. Supported at the upper part of the inner casing and swingable in a horizontal plane is a supporting structure for a bench top. The bench top is by means of a horizontal joint swingably connected to the supporting structure thus permitting swinging of the bench top in relation to the supporting structure and location of the bench top in freely selected, inclined positions.
