Abstract: Methods and apparatus to control hot-start weld current for arc ignition are disclosed. An example welding-type power supply includes a power converter to output welding-type current, a temperature monitor to determine a temperature of an electrode using at least one of a temperature measurement or a thermal model, and a current controller to control a hot-start weld current output by the power converter based on the temperature of the electrode.

Abstract: 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.
