Electric arc system for ablating a surface coating

摘要

An electrical arc system for ablating a portion of a surface coating from an electrically conductive wire along a selected cut-off line within a tolerance on the order of 0.001 of an inch. The arc is generated by electrodes insulated from each other inwardly beyond the selected cut-off line and arranged obliquely to the cut-off line and to the axis of the coated wire.
