METHOD FOR PRODUCING A VARIABLE FLOW OF MELTED MATERIAL AND ARTICLES THEREFROM

摘要

A method for generating a variable flow of melted material. The method may include: (a) providing first and second members, the members having a potential energy difference between them; (b) extending one or more members at a first average extension rate for a first period while producing an electrical arc; (c) extending one or more members at a second average extension rate for a second period while producing an electrical arc; (d) extending one or more members at a third average extension rate for a third period while producing an electrical arc; and (e) flowing a transport medium across the one or more members.
