short circuits and have a negative impact on the welding result, ulti-
mately causing damage to the welding torch!
• Check wire drive, welding torches, and liner elements for application-
related equipment and setting.
• Clean the wire feed rolls on a regular basis (depending on the degree
of soiling). Replace worn wire feed rolls.
