  • Current limiting secondary contact
    Patent number: 11897059
    Abstract: A welding-type system includes a welding torch comprising a contact tip to provide an electrode wire. A secondary contact in electrical contact with the electrode wire, the secondary contact located along a length of the electrode wire and before the contact tip. Each of the contact tip and the secondary contact are connected to a welding-type power source. A current limiting device coupling located between the welding-type power source and the secondary contact and configured to limit a current at the secondary contact.
    Type: Grant

  • Welding remote power supply connection
    Patent number: 10807183
    Abstract: Methods and apparatuses for welding remote power supply are disclosed. An example welding remote power supply includes a housing to house an electronic component. A connector secures an electrical cable to the housing, the electrical cable having at least one conductive wire and a sheathing. A conductive element is connected to the electronic component through the sheath and into contact with the conductive wire to electrically connect the conductive wire with the electronic component.
