Abstract: An example welding system includes a power supply configured to output welding power; a weld parameter feedback sensor configured to produce a weld feedback parameter corresponding to an actual weld condition during welding; and a welding program comprising: a first weld having first weld parameters; a second weld having second weld parameters, wherein the second weld follows the first weld; a controller configured to, in response to selection of the weld program for performing a welding job on a part: control the power supply to provide the welding power to a first weld operation based the first weld parameters; monitor first feedback from the power supply; control the power supply to provide the welding power to a second weld operation based the second weld parameters; monitor second feedback from the power supply; and determine whether at least one of the welding job or the part is acceptable.

Abstract: A welding system including an arc monitoring, training, and control system is disclosed. The welding system includes a power supply, controller, and associated memory. When a weld is performed, the weld command and weld feedback parameters can be stored in the memory, along with associated alarm limit values. During subsequent welds, the input weld commands and actual feedback values can be compared to the established limits, and a fault signal provided to an operator or supervisor when the value exceeds the established limits. The fault signals can be used for training operators, as well as providing monitoring signals, and can be stored with weld data in a database for later analysis. In addition, collected weld data can be used to determine when to clean, repair, or replace consumables, including, for example, contact tips, wire drive liners, and drive rolls, and to monitor usage of wire and gas.

Abstract: An example welding-type system, includes: a processor; and memory comprising machine readable instructions which, when executed, cause the processor to: collect a plurality of average instantaneous power measurements from a plurality of welding-type power sources associated with a single welding-type process; and determine a total power input to the welding-type process by summing the average instantaneous power measurements for each of the welding-type power sources.

Abstract: Welding power is generated by first generating two different current waveforms, and comparing the waveform values for control intervals to select which waveform provides the greater current. The waveforms are for different transfer modes, such as one for a pulsed arc portion, and another for a short-circuit transfer mode or for short-circuit clearing. The waveforms may be programmed by settings in a state machine. A balance or relative prioritization in the comparison may be influenced by user inputs. The resulting hybrid process has aspects of both spray transfer and short-circuit transfer modes.

Abstract: A controller for a welding system adapted to determine a value of a weld secondary parameter across a weld secondary component based on a sensed parameter is provided. The controller may also be adapted to compare the determined value to a reference value range and to alert a user to a presence and location of a weld secondary error when the determined value is outside the referenced value range.

Abstract: A system and method for stabilizing a welding arc is disclosed. The method of initiating the arc includes the steps of defining a wire feed speed based on a user selected wire feed speed and then abruptly reducing the wire feed speed before the wire feed speed reaches a relatively stabilized speed for welding, thereby allowing a welding arc to initiate and propagate to a generally steady state.
