Abstract
A welding system includes a power supply configured to output power to a welding device. The power supply is configured to alternate the power output between an arc phase and a hotwire phase. The power output in the arc phase produces an arc between a welding electrode and a workpiece, and the power output in the hotwire phase heats the welding electrode without producing an arc.
Claims20
A welding system, comprising:
- a power supply configured to output power to a welding device, wherein the power supply is configured to alternate the power output between an arc phase and a hotwire phase;
- wherein the power output in the arc phase produces an arc between a welding electrode and a workpiece;
- and
- wherein the power output in the hotwire phase heats the welding electrode without producing an arc.
1 more element
A welding power supply, comprising:
- control circuitry configured to cycle welding power output from the power supply to a welding electrode between an arc phase and a hotwire phase;
- wherein the control circuitry conditions the welding power to produce an arc between the welding electrode and a workpiece in the arc phase;
- and
- wherein the control circuitry conditions the welding power to heat the welding electrode without producing an arc in the hotwire phase.

A welding system, comprising:
- a welding torch configured to direct a welding electrode toward a workpiece;
- and
- a power supply configured to provide power to the welding torch in an arc phase and in a hotwire phase, alternating between the arc phase and the hotwire phase;
- wherein a current heats the welding electrode without producing an arc between the welding electrode and the workpiece in the hotwire phase.
