1. In attaching a workpiece to an electrically conductive support surface using one or more micro welds, a method comprising: providing a spot welding arrangement including an electrode having an elongated configuration extending to an electrode tip for electrically contacting the workpiece and for passing a welding current between the workpiece and the electrode tip; establishing a welding configuration of the electrode tip by exposing the electrode tip to a selected welding environment for use in forming a micro weld having a target set of weld parameters; and welding said workpiece to said support surface using the electrode tip in contact with the workpiece to form said micro weld having said target set of weld parameters by re-exposing said electrode tip to the selected welding environment in a way which maintains the welding configuration of the electrode tip for use in forming an additional micro weld having the target set of weld parameters.
