Abstract
A battery powered welding system is provided. In one welding system a battery powered welder includes control circuitry configured to control a welding power output converted from power from an external battery power source. The battery powered welder also includes a wire drive assembly coupled to the control circuitry and configured to feed a welding wire using power from the external battery power source. The battery powered welder includes a case integrally supporting and enclosing the control circuitry and the wire drive assembly. The case is not configured to enclose the external battery power source.
Claims20
A battery powered welder comprising:
- control circuitry configured to control a welding power output converted from power from an external battery power source;
- a wire drive assembly comprising a wire drive motor and one or more wire feed rollers, the wire drive assembly communicably coupled to the control circuitry and configured to feed a welding wire using power from the external battery power source;
- a wire feed speed control circuitry configured to generate one or more signals to regulate a voltage in the wire drive motor based on a reference wire feed speed level;
- and
- a case comprising a storage area within the case, the control circuitry, the wire drive assembly, and the wire feed speed control circuitry being enclosed by the case within the storage area, and the external battery power source not being enclosed by the case, the storage area configured to store at least one of a welding torch assembly, a work cable, or a battery cable within the storage area with the control circuitry, the wire drive assembly, and the wire feed speed control circuitry.
An externally powered welding system comprising:
- a MIG torch for performing a welding operation;
- control circuitry configured to control a welding power output converted from power from an external power source;
- a wire drive assembly comprising a wire drive motor and one or more wire feed rollers, the wire drive assembly communicably coupled to the control circuitry and configured to feed a welding wire using power from the external power source;
- a wire feed speed control circuitry configured to generate one or more signals to regulate a voltage in the wire drive motor based on a reference wire feed speed level;
- and
- a case comprising a storage area within the case, the control circuitry, the wire drive assembly, and the wire feed speed control circuitry being enclosed by the case within the storage area, and the external battery power source not being enclosed by the case, the storage area configured to store at least one of the MIG torch, a work cable, or a battery cable within the storage area with the control circuitry, the wire drive assembly, and the wire feed speed control circuitry.
An externally powered welder comprising:
- a welding power converter configured to receive power from an external battery power source;
- a weld output controller configured to control welding power output of the welding power converter;
- a wire drive controller configured to generate one or more signals to regulate a voltage in a wire drive motor based on a reference wire feed speed level;
- and
- a case comprising a storage area within the case, the welding power converter, the weld output controller, the wire drive controller, and the wire drive motor being enclosed by the case within the storage area, and the external battery power source not being enclosed by the case, the storage area configured to store at least one of the MIG torch, a work cable, or a battery cable within the storage area with the welding power converter, the weld output controller, the wire drive controller.
