Abstract: A data structure for weld programs associates configuration data for a welding system with a plurality of weld programs and weld sequence data. The data structure allows the welding system to be configured for a particular part, operator, or stage in a welding process, and to be easily reconfigured when the part, operator, or stage changes, providing improved efficiency and flexibility in operation.

Abstract: Welding wire preheating systems and methods are disclosed. An example welding method includes: receiving a signal indicative of initiation of welding process; prior to initiating a welding arc based on the received signal, controlling voltage or current applied to a welding electrode to preheat the electrode to a temperature above an ambient temperature but below a melting point of the welding electrode; monitoring feedback voltage to determine a termination of preheating; and terminating preheating prior to initiating the welding arc in accordance with a welding protocol.

Abstract: A pulsed welding regime includes a peak phase in which energy is added to an electrode and a weld puddle, and a molten ball begins to detach from the electrode, followed by a dabbing phase in which current is significantly reduced to place the ball in the weld puddle with addition of little or no energy. The resulting short circuit clears and the system proceeds to a background phase. The current in the dabbing phase is lower than the current during the background phase. The process may be specifically adapted for particular welding wires, and may be particularly well suited for use with cored wires. The dabbing phase allows for lower energy to be transferred to the sheath of such wires, and resets the arc length after each pulse cycle.

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 method and apparatus for providing welding type power is disclosed. The output is cyclical, and is a controlled voltage output during the background and/or peak and a controlled current output during the transition up and/or down. During the controlled current portion the output is responsive to output voltage.

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: In a welding system, a preheating process is carried out prior to initiation of a welding arc, such as upon depression of a trigger or switch on a welding torch. The preheating process involves generation and application of desired currents and voltages to a welding electrode from a power supply. Preheating is continued until the welding electrode reaches a desired temperature or resistance, which may be determined by reference to an increasing voltage, a decreasing current, a peaked and declining voltage, resistance and/or power measurements, and so forth. Following preheating, a desired welding process may begin with initiation of the welding arc.
