Which of the following most accurately describes the problem?

XPERIM EN TS are being conducted 1--4 by Metallisation Ltd., Dudley, with an electric-arc pistol to melt the feed wire. Full details of the pistol will not be released until the apparatus has reached the production stage, but an official of the concern told The Commercial Motor" that two wires are fed into the pistol and energized by an electric current which causes both wires to melt.

Compressed air, used in the normal coal-gas-oxygen pistols, caused interruption of the arc when-employed in the electric pistol. To overcome this difficulty the air for the electric pistol is passed over a radio-active isotope of phosphorus, a by-product from the Harwell atomic-energy station, which ionizes the air and makes it nonconductive. The metal-spray process is used to rebuild worn parts and protect metal surfaces against corrosion.
