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.
