CAUTION
Extensive wear due to incorrect contact pressure!
Incorrect contact pressure will cause extensive wear of the wire feed rollers!
• With the adjusting nuts of the pressure units set the contact pressure so that the wire
electrode is conveyed but will still slip through if the wire spool jams.
• Set the contact pressure of the front rollers (in wire feed direction) to a higher value!
•
Press the wire inching button until the wire electrode projects out of the welding torch.

without it jamming during operation!
