ABSTRACT:
Arc welding apparatus for use in conjunction with conventional link forming apparatus is operable for welding the closed ends of a link after it is formed. The electrode is mounted on a swinging arm which presents the electrode from the front of the assembly and positions the electrode substantially over the top of the link for welding thereof. The vertical, horizontal and angular positions of the electrode are adjustable by means of threaded adjustment knobs. A shield and gas tube are mounted adjacent to the tip end of the electrode and move simultaneously with the electrode into position over the link during a welding operation.
