  • Patent number: 11278981
    Abstract: A device for imparting a torsional force onto a wire has a base and a support mounted so as to be rotatable with respect to the base around an axis of rotation. The axis of rotation coincides with a wire path extending through the base and the support. Further, a wire clutching device is mounted on the support and adapted to engage at a wire guided along the wire path, and a rotation mechanism is provided which is adapted for rotating the support with respect to the base.

  • Patent number: 10350696
    Abstract: A wire feeding system, in particular for feeding a so called “cold wire” or wire with no tension nor signal running on its surface, in which the pulling or holding of the wire by the front wire feeder puts the rear pushing slave booster respectively into a pre-set active full motor torque or into a pre-set stand-by minimum motor torque, as needed. Alternatively, a wire feed system for feeding a so called “cold wire” or wire with no tension nor signal running on its surface, in which the rear pushing slave booster is remotely controlled by an optic sensor positioned nearby the torch and sensing the light of the torch welding or spraying arc.

  • Patent number: 10343231
    Abstract: An auxiliary wire feeder has a pushing device for advancing welding wire, a control device for controlling the pushing device, and an electric contact adapted for being in electrical connection with the welding wire. The electric contact is connected to the control device for supplying a control signal to the control device. A welding system comprises an auxiliary wire feeder of this kind and further a welding torch, a main wire feeder, a wire guide for guiding welding wire from a supply to the welding torch and a welding current contact for supplying welding current to the welding wire. For controlling an auxiliary wire feeder in a welding system having a welding torch, a main wire feeder, a wire guide for guiding welding wire from a supply to the welding torch, a welding current contact for supplying welding current to the welding wire, the control of the auxiliary welding wire feeder is responsive to an electrical signal transmitted via the welding wire.

  • Patent number: 10294065
    Abstract: A retainer is described for exerting a braking effect on wire provided as a spool in a container. The retainer has a plate-like elastic element with a contact surface adapted for resting on the wire, an outer circumference adapted for being guided in the container, and an inner circumference adapted for allowing the wire to pass through. The plate-like elastic element has an elasticity such that one of the inner and outer circumferences sags down, under the proper weight of the retainer, by a distance of at least 10 mm when the retainer is supported at the other of the inner and outer circumference.

  • Patent number: 9975728
    Abstract: A wire feeding system comprises a wire container including a box having an open upper side, and a wire container lid closing the upper side. The wire container lid includes a front wall having an opening through which wire is to be paid off. A wire outlet guide is attached to the front wall. The wire outlet guide comprises an upper and a lower hole for receiving the wire, the upper and lower holes being defined by a lower ring wall and an upper ring wall, respectively, and being distanced from each other in a wire feeding direction. At least the lower ring wall limits sideward movement of the wire and allows contact with the wire. The holes have a fixed position relative to the front wall. A deflection space bridging the distance between the holes allows sideward deflection of the wire between the ring walls.
