  • Patent number: 4199096
    Abstract: An improved soldering device is provided, one that is structured for the reception of and use with a new cartridge that is a self-contained supply of solder. When the cartridge is inserted within the soldering device, an operator, using only one hand, is able to advance the solder from out of the cartridge and to a location in close proximity with the soldering tip of the device. With that same single hand, the operator can energize the heating element to supply heat to the soldering tip. The advancing and energizing structure permits the device to remain energized throughout the advancing operation or, optionally, to smoothly effect an intermittent energization and deenergization of the heating element to reduce the total quantity of heat supplied to the soldering tip even while the solder is being advanced.

  • Patent number: 3990622
    Abstract: Soldering method and apparatus comprising a soldering device having a hand grip portion and an electrically heated soldering element extending from said hand grip portion and terminating in a soldering tip, a housing structure adapted to be supported in a position disposed in spaced relation from the solder device, the housing structure supporting a solder wire supply spool to be unwound therefrom, a tubing structure extending from the housing structure and connected with the soldering device for closely peripherally confining a leading portion of solder wire of substantial longitudinal extent extending from the spool with the free end thereof adjacent the soldering tip and for maintaining such confinement during longitudinal movement thereof in a direction wherein the free end engages the soldering tip while enabling the soldering device to be substantially freely manually moved in spaced relation relative to the housing structure by an operator grasping the hand grip portion thereof, the tubing structure in
