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.
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.

Abstract:
A wire feeding system, in particular for feeding welding wire, has a wire movement sensing device adapted for being mounted onto a wire guideliner, and a feed assisting device for feeding welding wire depending from signals received from the wire movement sensing device.
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.
Abstract:
A liner for guiding wire, in particular welding wire, is formed from at least two different types of bodies arranged successively so as to form the liner. Each of the bodies carries a set of rolling elements.
