A pivotally adjustable welding electrode support is used to permit remote adjustment of the contact angle of the welding electrode with the material to be welded. The use of a modified parallelogram construction of the holding arm in combination with the use of hinges and a ball joint allow the torch or electrode to be moved not only in the horizontal and vertical plane but also permit remote rotational adjustment of the electrode to change the angle that the electrode makes with the horizontal plane. A ball socket supports the parallelogram structure of the arm. The modified parallelogram support linkage of the arm comprises two adjoining parallelogram shaped sections; one section is vertically offset from the other section. Each edge of each parallelogram shaped section contains a hinge to support movement of the electrode to change the angle of the electrode with the forge die or workpiece.
