Filed:

Apr 16, 2004

Appl. No.:

10/709148

Inventors:

Brian L. Ott - Hilbert WI, US

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

B23K 9/10

US Classification:

219132

Abstract:

The present invention is directed to a remotely controlled welding machine that uses serializing and modulating circuits to transfer modulated data packets to a welding power source across a weld cable. A transmitter transmits the data packets of desired welding operational parameters to a receiver disposed in the power source across a weld cable also designed to carry welding power from the power source to the wire feeder. The transmitter and other electronics of the wire feeder are constructed to use only a small amount of power which, preferably, is supplied by a DC power supply external to the wire feeder. The DC power supply is designed to provide power to the electronics of the wire feeder when the wire feeder is in a standby mode of operation.

10/907179

Inventors:

Brian L. Ott - Sherwood WI, US

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

B23K 9/10

US Classification:

219132

Abstract:

The present invention includes a system and method of controlling a remotely located welding-type power source. A communications system includes a user interface to accept a user input at a portable location and a gas purging device to systematically purge pressurized gas from a gas line connecting the portable location to a remote location based on the user input. The communications system also includes a sensor to sense pressure changes in the gas line at the remote location and a processor configured to convert the sensed pressure changes to a representation of the user input.

International Classification:

H05B 7/11

US Classification:

219132, 219136, 219137 PS

Abstract:

The present invention is directed to a system and method of remotely controlling a welding machine with command signals transmitted to the welding power source across a weld cable connecting the power source to a remote device, such a wire feeder. A transmitter transmits the control commands containing desired welding operational parameters to a receiver disposed in the power source across a weld cable also designed to carry welding power from the power source to the wire feeder.

US Classification:

219 732, 219108

Abstract:

Various welding systems that provide communication over auxiliary or weld power lines are provided. The disclosed embodiments may include a multi-process welding power supply that is communicatively coupled to a pendant via an auxiliary conduit that facilitates the exchange of data and power between components of the welding system. In some embodiments, the pendant may also include auxiliary outlets that allow an operator to power auxiliary devices at the weld location. The disclosed embodiments further include a pendant with a wire spool and wire feeder drive circuitry that is configured to activate spooling during MIG welding. Embodiments are provided that also allow for bidirectional data communication over a power line in networked welding systems.

International Classification:

B23K 9/10

US Classification:

21913771

Abstract:

A welding wire feeder includes a magnetic rotational sensor system configured to measure a parameter indicative of a wire feed speed of the welding wire feeder. The magnetic rotational sensor system includes a dipole magnet coupled to a gear driven by an electric motor of the welding wire feeder and a magnetic sensor disposed adjacent to the dipole magnet and configured to measure an angular position of the dipole magnet. The magnetic rotational sensor system also includes a processor configured to receive signals of the angular position measured by the magnetic sensor and to calculate a wire feed speed of the welding wire feeder based upon the angular position signals and configuration parameters of the welding wire feeder.

International Classification:

B23K 11/24

US Classification:

219108

Abstract:

An external control module is provided for interfacing a welding power supply with a wire feeder. The welding power supply is designed to exchange control signals, feedback signals, and so forth over a control cable when coupled to a standard wire feeder. However, the external control module allows the power supply to be used with a wire feeder that is designed to exchange data combined in a single cable with welding power. The module is coupled to welding and workpiece cables from the power supply, and to a control cable, such as from a multipin connector on the power supply. The module is further coupled to the wire feeder via a welding cable. The module combines data with welding power for transmission to the wire feeder, and extracts data from welding power for application to the power supply.
