Abstract
Systems and methods are disclosed for automatically isolating a gouging power output from a welding power output responsive to a weld process selection. In particular, the disclosed systems and methods provide isolation circuitry to isolate the welding power output from the gouging power output, such that power conversion circuitry provides the gouging power to the gouging power output and prevents any power to the welding power output
Claims20
A wire feeder, comprising:
- isolation circuitry between a welding power output and a gouging power output to automatically isolate one power output from the other power output responsive to a weld process selection;
- and
- control circuitry configured to:
- receive a weld process selection input to provide gouging power;
- transmit a control signal to a welding power supply to provide the gouging power;
- control the isolation circuitry to isolate the welding power output from the gouging power output;
- and
- control power conversion circuitry to provide the gouging power to the gouging power output.
5 more elements
A system, comprising:
- a welding power supply to supply a power output;
- one or more welding torches;
- and
- a wire feeder coupled between the welding power supply and the one or more welding torches, the wire feeder comprising:
- isolation circuitry to physically or electrically isolate a welding power output from a gouging power output;
- and
- control circuitry configured to:
- receive an input to provide gouging power;
- control the isolation circuitry to isolate the welding power output from the gouging power output;
- and
- control power conversion circuitry to provide the gouging power to the gouging power output.
8 more elements
A welding system, comprising:
- a welding power supply to supply a power output, the welding power supply comprising first power conversion circuitry;
- and
- a wire feeder comprising:
- isolation circuitry to physically or electrically isolate a welding power output from a gouging power output;
- and
- control circuitry configured to:
- receive an input to provide gouging power;
- transmit a control signal to the welding power supply to control the power conversion circuitry to adjust a polarity of the power output for gouging power;
- control the isolation circuitry to isolate the welding power output from the gouging power output;
- and
- control second power conversion circuitry to provide the gouging power via the gouging power output.
