The low power receiver is configured to transmit one or more unmodulated tones through the weld cable to a welding power supply. The low power receiver is configured to receive the one or more unmodulated tones through the weld cable from the welding power supply. The first processor is configured to determine one or more channel equalization filter coefficients related to the weld cable corresponding to a distortive characteristic of the weld cable.
Abstract:
A system and methods for electrically starting an arc in a welding process are disclosed. The system and methods may reduce an electromagnetic interference (EMI) footprint during the arc start by reducing the average power spectral density output and broadening the frequency spectrum of the arc EMI footprint. In one embodiment, a welding system may include a welding torch and a welding power source electrically coupled to the welding torch via a weld cable configured to supply electrical energy to the welding torch. The welding power source may include pseudo-random noise (PRN) generator control logic circuitry configured to generate a dithered pulse waveform with a pseudo-randomly selected data sequence of binary values based on one or more baselines, and to apply the dithered pulse waveform to an oscillator during arc starting in a tungsten inert gas (TIG) welding process performed by the welding torch.
Abstract:
Embodiments described herein include wireless control of a welding power supply via portable electronic devices. In particular, operating parameters and statuses of the welding power supply may be modified by the portable electronic device, as well as be displayed on the portable electronic device. For example, in certain embodiments, the welding power supply may be an engine-driven welding power supply, and the portable electronic device may be configured to start and/or stop an engine of the engine-driven welding power supply. A pairing procedure may be used to pair the welding power supply and the portable electronic device in a wireless communication network. Furthermore, in certain embodiments, a method of prioritization of control between a control panel of the welding power supply and the portable electronic device may be implemented.
