5.4.6.1 Burn-back
The wire burn-back parameter prevents the sticking of the wire electrode in the weld pool or at the contact
tip at the end of the welding process. The value is optimally preset for a variety of applications (but can be
adjusted if necessary). The adjustable value stands for the time until the power source switches off the
welding current after the welding process has been stopped.
