## Abstract

A welding system includes a torch motion sensing system associated with a welding torch and is configured to sense welding torch orientations or movements. The welding system also includes a processing system that is configured to vary operation of a power source based on the sensed orientations or movements.

## Claims

### Claim 1

A method comprising:
sensing an initial orientation of a welding-type tool or accessory via a motion sensing system;
sensing a subsequent orientation of the welding-type tool or accessory via the motion sensing system;
activating a power source associated with the welding-type tool or accessory if the power source is turned off and the subsequent orientation differs from the initial orientation; and
activating a higher power state for the power source if the power source is in a low-power state and the subsequent orientation differs from the initial orientation.

### Claim 2 (depends on 1)

The method of claim 1, comprising placing the power source in the low-power state if the power source is in a high-power state and the subsequent orientation does not vary from the initial orientation, wherein the subsequent orientation occurs after the initial orientation by at least a predefined duration of time.

### Claim 3 (depends on 2)

The method of claim 2, comprising:
placing the power source in the off state if the power source is in the high-power state and another subsequent orientation does not vary from the initial orientation, wherein the another subsequent orientation occurs after the initial orientation by at least a longer predefined duration of time.

### Claim 4 (depends on 1)

The method of claim 1, wherein the low-power state comprises an idle state for the power source.

### Claim 5 (depends on 1)

The method of claim 1, comprising placing the power source in the off state if the power source is in a high-power state and the subsequent orientation does not vary from the initial orientation, wherein the subsequent orientation occurs after the initial orientation by at least a predefined duration of time.

### Claim 6 (depends on 1)

The method of claim 1, comprising indicating a state of the power source by:
providing visual feedback;
providing audible feedback; or providing haptic feedback.
