Abstract
A wire feeder that is powered at least partially by a battery is provided. The wire feeder includes a welding wire spool and a welding wire drive system for receiving welding wire from the spool and feeding the wire through a flexible conduit attached to an enclosure of the wire feeder. A motor of the wire feeder drives the welding wire drive system, powered at least in part by the battery. The wire feeder includes a battery receptacle for receiving the battery. In certain embodiments, the wire feeder may be attached to a body of a user via a harness system.
Claims17
A portable, battery powered wire feeder for tungsten inert gas (TIG) welding, comprising:
- an enclosure, wherein the enclosure comprises:
- a hub for receiving a welding wire spool;
- a welding wire drive system for receiving welding wire from the welding wire spool and feeding the welding wire through a flexible conduit attached to the enclosure, the flexible conduit to deliver the welding wire to a workpiece, the welding wire to be melted by a tungsten inert gas (TIG) welding torch at the workpiece, the TIG welding torch comprising a non-consumable tungsten electrode that is independent from the welding wire from the spool,
- wherein an entirety of the flexible conduit is independently movable and separate from a cable supplying power and gas to the TIG welding torch that consumes the welding wire as the welding wire is fed through the flexible conduit during a TIG welding operation;
- a motor for driving the welding wire drive system, wherein the motor is powered at least in part by a battery;
- and
- a battery receptacle for receiving the battery.
A portable, cordless wire feeder system for tungsten inert gas (TIG) welding comprising:
- a welding wire feeder, comprising:
- a hub for receiving a welding wire spool;
- a welding wire drive system for receiving welding wire from the welding wire spool and feeding the welding wire through a flexible conduit and delivering the welding wire to a workpiece, the welding wire to be melted by a TIG welding torch at the workpiece, the TIG welding torch comprising a non-consumable tungsten electrode that is independent from the welding wire from the spool;
- a motor for driving the welding wire drive system, wherein the motor is powered at least in part by a battery;
- a trigger to activate the motor to drive the welding wire drive system during a TIG welding operation, the trigger being independent of a trigger for the TIG welding torch;
- a battery receptacle for receiving the battery;
- and
- a harness system for attaching the welding wire feeder to a body of a user.
