<p>Electrodes for the spot welding machine comprise a part supporting the welding tip articulated so as to be able to swing between a working position and an inactive position w.r.t. a support connected fixed or moveable to the frame of a spot welding machine. A hydraulic actuator is pivoted on this support and is also articulated to the swing part, so as to control its movement from the working to the inactive position and vice versa.</p> |
