  • Coaxial welding cable assembly
    Patent number: 9579743
    Abstract: A lighter weight, more flexible coaxial welding cable assembly, and a system and method for constructing same. An embodiment of the coaxial welding cable assembly comprises a central electrical conductor length having a first cross-sectional area and a first insulating jacket surrounding the central electrical conductor length. The coaxial welding cable assembly also includes a plurality of peripheral electrical conductor lengths surrounding the insulated central electrical conductor length, where a total cross-sectional area of the plurality of peripheral electrical conductor lengths is approximately the same as the first cross-sectional area of the central electrical conductor length. The central electrical conductor length is electrically insulated from the plurality of peripheral electrical conductor lengths only by the first electrically insulating jacket.

  • Wire feeder with curved force generating element(s) for better positioning of an adjusting mechanism
    Patent number: 8878097
    Abstract: An apparatus for feeding a wire. The apparatus includes at least one pair of rotatable rollers and at least one curved or curvable force-generating element. The at least one curved or curvable force-generating element is capable of applying a force via a proximal end of the at least one curved or curvable force-generating element to displace a first roller of the at least one pair of rotatable rollers towards a second roller of the at least one pair of the rotatable rollers to engage a wire there between. The apparatus further includes an adjustment mechanism operationally connected at a distal end of the at least one curved or curvable force-generating element to allow adjustment of the applied force.
