General
Function prin- The WireEnd Control informs you in good time that a wire spool change is imminent.
ciple This means that the production sequence is not interrupted unexpectedly during the
welding process.
The WireEnd Control is based on the principle of an induction sensor that permanently
scans the wire spool. When the last welding wire position has been unrolled the sensor
inductance changes. An electronic switch registers this change, evaluates the data and
emits a wire end alarm.
IMPORTANT! The wire end alarm does not interrupt the welding process.
