Abstract
Abstract An electrode for use in cutting or gouging metal by means of the Air carbon arc-cutting process. The electrode has a flexible structure which enables it to be stored on a reel and to be continuously fed therefrom into a metal-cutting zone by an automatic holder. The electrode comprises a series of relatively short, tubular segments of carbonaceous material disposed in endto-end relation on a consumable metal wire extending lengthwise through the centers of the segments, and an electrically conductive, flexible covering surrounds and extends along the segments to protect them from damage. The carbonaceous segments carry the major portion of the current supplied to the electrode with the metal wire and covering providing secondary and tertiary electron flow paths for improving the current-carrying capacity of the electrode.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
A flexible electrode structure, comprising: a series of relatively short tubular segments of carbonaceous material disposed in end-to-end relation with the confronting surfaces of adjacent segments being in operative contact with one another at an interface to form a first path for transferring electrical energy; elastic coating means surrounding said segments and spanning across each interface to provide an additional path for transferring electrical energy between the segments, said elastic coating means being electrically conductive and tightly engaging the outer periphery of the segments to cause the same to abut one another in end-to-end relation when disposed in a substantially straight line and to enable the segments to at least partially disengage each other when disposed in an arc; and flexible means forming a continuous elongated core element disposed axially in said segments and spanning across each interface operatively to maintain said segments in proper endwise registry with one another whereby a flexible electrode is provided.
Claim 2
Dependent Claim
156 words
A flexible electrode structure, comprising: a series of relatively short tubular segments of carbonaceous material disposed in end-to-end relation with the confronting surfaces of adjacent segments being in operative contact with one another at an interface to form a first path for transferring electrical energy; elastic coating means surrounding said segments and spanning across each interface to provide an additional path for transferring electrical energy between the segments, said elastic coating means being electrically conductive and tightly engaging the outer periphery of the segments to cause the same to abut one another in end-to-end relation when disposed in a substantially straight line and to enable the segments to at least partially disengage each other when disposed in an arc; and flexible means forming a continuous elongated core element disposed axially in said segments and spanning across each interface operatively to maintain said segments in proper endwise registry with one another whereby a flexible electrode is provided.
Claim 3
Dependent Claim
33 words
An electrode structure according to claim 1 wherein said flexible-core means includes a wire having a disintegrating temperature corresponding approximately to the temperature at which said segments are disintegrated by an electric arc.
Claim 4
Dependent Claim
36 words
An electrode structure according to claim 1 wherein said elastic-coating means surrounding said segments is metallic and has a melting temperature corresponding approximately to the temperature at which said segments are disintegrated by an electric arc.
Claim 5
Dependent Claim
19 words
An electrode structure according to claim 1 wherein said elastic-coating means is copper and is plated onto said segments.
Claim 6
Dependent Claim
16 words
An electrode structure according to claim 1 wherein said elastic-coating means is an electrically conductive hydrocarbon.
