The invention relates to an item of jewelry, comprising a fastener, an outer part, and an inner part rotatable therein. First, the method forms basic elements on a semiconductor base. The solution applicator is oriented to spray the solution onto the product surface thereby removing the contaminants from the product surface. The positioning attachment may be mounted on the welding torch nozzle or provided as an extension of the contact tip. The polymer of an -olefin is useful as a component of lubricant.
