Abstract
A method of adjusting a wire feeder having a pusher system (12) and a puller system (14) to avoid birdnesting and collapse of the wire (11) in the wire guide or conduit (13) when the tip (15) of the wire feeder is blocked or a wire jam occurs. The pusher system (12) is adjusted by activating both the pusher system (12) and the puller system (14), adjusting the pusher system (12) to provide a desired wire feed speed when the tip (15) is not blocked, blocking the tip (15), and adjusting the pressure exerted by the rollers (22) of the pusher system (12) so that these rollers (22) slip on the wire (11) when the tip (15) is blocked. The puller system (14) is adjusted by disabling the pusher system (12), blocking the tip (15), activating the puller system (14), and adjusting the pressure exerted by the rollers (32) of the puller system (14) so that these rollers (32) do not slip on the wire (11). In addition, the braking rate of the motor (20) of the pusher system (12) and the braking rate of the motor (30) of the puller system (14) are adjusted so that the pusher system (12) brakes at a faster rate than the puller system (14) and the wire (11) is maintained in tension. These steps keep the wire (11) in tension in normal operation and also prevent the wire (11) from collapsing or being jammed in the wire guide (13) when the tip (15) is blocked for any reason, such as by wire shavings.
