Welding system with controlled wire feed speed during arc initiation
A welding system including a power supply, a torch electrically connected to said power supply, a wire feeder that provides a welding consumable to the torch, a controller that communicates with a motor associated the wire feeder and the power supply. The controller obtains a wire feed speed of said motor as it accelerates from a run-in speed to a pre-set speed and controls the power supplied to the torch based on this wire feed speed to reduce stubbing or spattering during arc initiation.

Systems and methods for controlling arc initiation and termination in a welding process
Systems and methods for initiating and/or terminating a GMAW-P welding process are disclosed. A welding-type power supply may include a power conversion circuitry configured to convert input power to welding-type power, and a controller configured to control the power conversion circuitry based on a plurality of operating parameters. In examples, the systems and methods disclosed herein implement pulsed cycles with one or more increased output parameters (such as current, pulse width, etc.) in order to jump start a pulsed welding cycle at a cold start (i.e. at initiation of a welding process), and thereby prevent a ball forming and remaining on the end of an electrode wire as the welding process continues. In a similar manner, a pulsed cycle with one or more increased parameters can be used to terminate the welding process, also preventing the ball forming and remaining on the electrode wire.
ENGINE DRIVE WELDER AND METHODS AND SYSTEMS OF CONTROLLING THE SAME
A welding or cutting device includes an internal combustion engine coupled to a generator for generating electrical power. A welding or cutting power supply is powered by the generator. The welding or cutting power supply supplies a welding or cutting output signal. An auxiliary outlet circuit is configured to receive power from the generator. The auxiliary outlet circuit includes at least one auxiliary load outlet. A controller controls an engine speed of the internal combustion engine. The controller is configured to determine an anticipated load on the generator to be supplied through the auxiliary load outlet, based on a no load condition of the auxiliary load outlet, and adjust an idle speed of the engine based on the anticipated load. The controller is further configured to subsequently increase the engine speed, from the idle speed to an auxiliary load speed, when the generator supplies power through the auxiliary load outlet.
INITIATION OF WELDING ARC BY RESTRICTING OUTPUT
Systems and methods for providing an improved start in a welding process are provided. The system may include a power circuit and a control circuit. The power circuit can generate a welding output power. The control circuit may be in communication with the power circuit to control, during the start of the welding process, at least one welding parameter until the control circuit determines that welding energy output exceeds an energy output threshold.
Method to improve process stabilization
Systems and methods for providing an improved start in a welding are provided. The system may include a power circuit and a control circuit: The power circuit may generate welding output power for a welding process.

Method and Apparatus For Welding With Improved Start
A method and apparatus for starting a wire fed weld operation includes monitoring at least one of a prior run-in time, a prior run in distance, a prior run in wire feed speed, and/or whether or not there is contact at the time of a prior start. Then the wire position is controlled for a present weld operation in response to the monitored data.
