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.
Claims20
A wire feeding system, comprising:
- 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 the temperature of the electrode wire.
A welding-type system, comprising:
- a wire feed motor to advance electrode wire to a welding torch;
- a welding-type power source to provide welding-type power to the 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 the temperature of the electrode wire.
A non-transitory machine readable medium comprising machine readable instructions which, when executed, cause a control circuit to:
- identify an end of a welding arc at a welding torch;
- select a run-in wire speed based on a temperature of electrode wire to be fed by the welding torch;
- identify a trigger actuation event at the welding torch;
- and
- control a wire feeder to feed the electrode wire at the run-in wire speed.
