Abstract
A pair of welding tongs includes two moveable tong arms, with each tong arm including a first arm element with an electrode, a second arm element, and a connecting element disposed between the first and second arm elements, whereby the connecting elements of the tong arms can rotate about a common fixed reference point. An articulated lever is connected to the second arm element. The pair of welding tongs further includes a mechanical coupling to link the articulated levers of the tong arms, and a drive unit for driving the mechanical coupling. The motion of the mechanical coupling is transmitted to each tong arm of the welding tongs.
