Abstract
A method and system to determine optimum operating parameters for the startup phase of a welding-type process based on user-desired operating parameters of the post-startup or welding phase of the welding-type process are disclosed. While applicable to a number of welding-type processes, the method and system are particularly configured to determine an optimum wire feed speed for Gas Metal Arc Welding of aluminum using pulse spray transfer.

-30. (canceled)
A welding-type device comprising a controller configured to:
- receive an input value for a welding-type parameter related to wire feed speed, the welding-type parameter designed to establish an operation of a welding-type process;
- determine an offset value to the input value for the welding-type parameter, the offset value designed to establish an operation of the welding-type process during a startup period of the welding-type process;
- and
- selectively control the welding-type process based on a selection between the offset value and the input value.
A controller for a welding-type system, the controller configured to:
- determine a first set of operating parameters related to wire feed speed designed to govern a welding-type process after an initialization period;
- determine a second set of operating parameters related to wire feed speed designed to govern the welding-type process during the initialization period based on the first set of operating parameters;
- and
- carry out the welding-type process such that a selection between the first set of parameters and the second set of parameters governs the welding-type process during the initialization period and the first set of operating parameters governs the welding-type process after the initialization period.
