Abstract
An arc spot welding equipment wherein a hand having a positioning and clamping device for a work and a welding torch is attached to an arm of an industrial robot. The small work is clamped in a predetermined positional relation to the welding torch and is moved by the arm of the robot to an object to which said work is to be welded, thereby realizing an automatic positioning of the work to the object and eliminating the need to prepare a large-scale jig for positioning and clamping work to reduce the cost of the equipment.
