Abstract:

A waterproof electrode useful in metal-working is obtained by coating the electrode with a polyolefin selected from the class consisting of polyethylene, polypropylene, polybutylene and mixtures thereof at a thickness from 0.25 cm to 0.80 cm by a method which comprises placing the electrode inside a polyolefinic heat-shrinkable tubing of a length sufficient to cover at least 0.6 cm of the bare metal of an electrode with a flux coating and sufficient to extend at least 0.8 cm beyond the electrode and with a diameter and a shrinkability sufficient to bring the polyolefin in contact with the bare metal of a flux-coated electrode.
