Zusammenfassung:	Methods and apparatus to control advancement of a welding electrode wire for arc ignition are disclosed. An example electrode wire feeder includes a wire feed motor to advance electrode wire to a welding torch, a temperature monitor to determine a temperature of the electrode wire using at least one of a temperature measurement or a thermal model, and a motor controller to control a run-in wire speed based on a temperature of the electrode wire.
