A system and method to make a welder aware of contact tip-to-work distance (CTWD) during a welding process. One or both of welding output current and wire feed speed is sampled in real time during the welding process. The actual CTWD is determined in real time based on at least one or both of the sampled welding output current and wire feed speed. The actual CTWD may be compared to a target CTWD in real time, where the target CTWD represents an estimated or desired CTWD for the welding process. A deviation parameter may be generated based on the comparing. An indication of the deviation parameter or the actual CTWD may be provided to a welder performing the welding process as feedback, allowing the welder to adjust the actual CTWD to better match the target CTWD in real time during the welding process.
A method, comprising:
A welding system, comprising a welding power source, wherein the welding power source is configured to:
A welding power source, comprising a controller, wherein the controller is configured to determine an actual contact tip-to-work distance (CTWD) in real time based on a relationship of CTWD with at least one of a welding output current and a wire feed speed, wherein the relationship is selected from a plurality of relationships stored in the welding power source, based on a correspondence to inputs including a wire type and a wire size utilized to create a weld and a shielding gas type used during creation of the weld, and wherein the actual CTWD is determined from the relationship using at least one of the welding output current or the wire feed speed sampled during creation of the weld.
