Abstract
Abstract Welding cable and equipment wherein welding cable is color-coded and comprises respective composite cables that individually have as components a power cable and, attached thereto, a control cable. Color coding may be provided by paint, dye or other means at cable areas remote from natural wear areas. Preferably at least one of the cable elements of the composite welding cable will be provided with a durable rubber or other sheath that can accommodate heavy wear areas and abrasive conditions. Welding equipment is provided such that a maze of composite welding cables can be individually identified and manipulated, used and routed accordingly.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
207 words
Welding equipment comprising a control cable comprising a plurality of individually insulated control wires bundled together and having a common insulating jacket therearound; a power cable comprising a power conductive core made of bundled non-insulated core wires surrounded by the common insulating jacket, said power cable having a larger diameter than the control cable whereby an elongate, recessed medial portion is formed in the common insulating jacket at opposite sides of the welding cable between the control cable and the power cable; color coding means permanently affixed to the control cable and the power cable, said color coding extending into the recessed medial portion formed between the control cable and the power cable at opposite sides of the welding cable to be protected during dragging of the welding cable, whereby upon splitting of a portion of the control cable from the power cable the color coding common to the welding cable will split to become part of each split cable and will be easily viewed as continuing from each opposite side of the welding cable as part of such split apart control and power cables; and additional color coding means corresponding in color to the color coding means and including means for attachment to a welding machine.
