摘要:
Disclosed welding-type systems and methods are directed to employing a wire feeder for feeding an electrode wire from a wire source in a welding system. The wire feeder includes one or more drive rolls to advance the electrode wire by contact force. In disclosed examples, a contact force on the wire from the drive rolls is adjustable. In some examples, the system includes a controller to receive a feedback signal corresponding to the contact force. The controller commands an actuator or other mechanism to adjust the contact force on the wire, such as by adjusting a position of the one or more drive rolls in response to the contact force falling outside a range of threshold contact force values.
