Abstract

Devices and methods for indicating power on a torch. In one example, a welding or plasma cutting torch includes an indicator coupled to the torch. The torch also includes control circuitry coupled to the indicator and configured to provide a first signal and a second signal to the indicator. The indicator is configured to receive the first signal when at least one of welding power and arc starting power from a power supply is available at the torch and to receive the second signal when the at least one of active welding power and the arc starting power from the power supply is not available at the torch.

First claim

The invention claimed is:

1. A welding or plasma cutting torch, comprising:
an indicator coupled to a body of the torch; and
control circuitry coupled to the indicator and configured to provide a first signal and a second signal to the indicator;
wherein the indicator is configured to receive the first signal when at least one of welding power and arc starting power from a power supply is available at the torch, the indicator is configured to receive the second signal when the…
