A resistance welding head carries out resistance welding while clamping spots are being welded by a pair of electrodes. The head is floated in a direction Y perpendicular to a direction X of juxtaposing the spots being welded. The pair of electrodes clamp the spots being welded while centering by acting a reaction force exerted when the electrodes clamp the spots to the resistance welding head. Then, resistance welding starts.

Wires w-,, w-,are laid along the inner surfaces of lower and upper casings,, and are connected with push-in terminals driven into connectors mounted in the lower and upper casings,. The ends of the wires in the upper and lower casings to be connected at the same lateral side of the casing have their insulating coatings stripped off to expose cores, which are connected with the upper and lower sides of U-shaped connection busbars,arranged on the side of the lower and upper casings.

To position a wire-connected terminal TW and cope with a multitude of kinds of wire-connected terminals TW, a block 30 is provided for each wire-connected terminal TW. The block 30 includes recesses 34, 37 for detachably accommodating the wire-connected terminal TW. A part of the accommodated wire-connected terminal TW is exposed such that it can be gripped by hands 51, 52. The block 30 also includes a positioning means 38 for positioning the terminal TW accommodated in the recesses 34, 37 with respect to the hands 51, 52. Since the terminal TW is securely positioned in a transferring step of transferring the wire-connected terminal TW to the hands 51, 52, the succeeding step performed by the hands 51, 52 can be securely performed.
