A welding head for connecting weld members by resistance welding includes an infeed cylinder having a piston rod, an electrode movable via the cylinder; and a sensor arranged between the piston rod of the infeed cylinder and a readjusting spring for the rapid readjustment of the electrode. The sensor is clamped in place between contact means in a sleeve-shaped or tubular drive shaft mounted in a housing.
