Abstract
A wire feeder includes a tensioner with a discrete number of compressive force settings for applying a desired compressive force to welding wire fed through the wire feeder is provided. The tensioner includes an adjustment knob with a discrete number of detents disposed along a helical surface adjacent an inner bore of the adjustment knob. The tensioner also includes a pin extending from an end of a tensioning post located in the inner bore, the pin being configured to align with the detents of the adjustment knob. Rotation of the adjustment knob adjusts alignment of the pin among the discrete number of detents, which correspond to the discrete number of compressive force settings.
