Abstract

A welding system comprising a user manipulatable device, a proximity sensor positioned on said user manipulatable device, an engine capable of operation in an energy conservation mode and an operating mode, and a generator operatively coupled to the engine. The generator may provide at least one of (1) a welding current output or (2) an auxiliary power output. The engine may operate (1) in the operating mode when the proximity sensor outputs the first output signal, and (2) in the energy conservation mode when the engine is not operating in the operating mode. The proximity sensor may be configured to output the first output signal when an operator of said welding system is in-range.

First claim

What is claimed is:

1. A welding system comprising:
control circuitry operatively coupled with a trigger and a proximity sensor,
wherein the trigger is positioned on a welding torch and is configured to provide a control signal upon actuation by an operator of the welding system, and
wherein the proximity sensor is positioned on the welding torch and is configured to provide a first output signal while the proximity sensor detects that the operator is in-range of the welding torch;

an engine operatively coupled with the control circuitry, the engine being capable of operation in an energy conservation mode and an operating mode,
wherein the engine operates in the operating mode when the proximity sensor provides the first output signal to the control circuitry, and
wherein the engine operates in the energy conservation mode when the engine is operational and not operating in the operating mode; and

a generator operatively coupled to the engine and configured to supply power to welding circuitry,
wherein the welding circuitry is configured to provide when the proximity sensor provides the first output signal to the control circuitry, a welding current output in response to the control signal, and
wherein the control circuitry is configured to disable at least one power-drawing circuit of the welding circuitry when the proximity sensor does not provide the first output signal to the control circuitry.

2. The welding system of claim 1 , wherein the proximity sensor is configured to provide a second output signal when the operator is out-of-range.

3. The welding system of claim 2 , wherein the engine operates in the energy conservation mode when the proximity sensor provides the second output signal.

4. The welding system of claim 1 , wherein the proximity sensor is an RFID reader to determine whether an RFID tag associated with the operator is within a predetermined distance of the welding torch.

5. The welding system of claim 4 , wherein the RFID tag is a bracelet or an ID badge.

6. The welding system of claim 1 , wherein the proximity sensor is an accelerometer to determine whether the welding torch is in free fall.

7. The welding system of claim 1 , wherein the welding torch includes a handle, the proximity sensor being positioned on the handle.

8. The welding system of claim 1 , wherein the proximity sensor is positioned on the trigger.

9. The welding system of claim 1 , wherein the control circuitry is coupled to a timer and the control circuitry is configured to switch the engine between the operating mode and the energy conservation mode as a function of the first output signal and the timer.

10. The welding system of claim 8 , wherein the control circuitry is configured to operate the engine in the operating mode for a predetermine period of time after the proximity sensor terminates the first output signal.

11. The welding system of claim 1 , wherein the engine is configured to operate at a first speed during the energy conservation mode and at a second speed during the operation mode, the second speed being greater than the first speeds.

12. The welding system of claim 11 , wherein the first speed is an idle speed.

13. The welding system of claim 12 , wherein the second speed is a run speed.
