• Extend and lay out the torch hose package.
• Unfasten pressure units and fold out (clamping units and pressure rollers will automatically flip up-
wards).
• Unwind welding wire carefully from the wire spool and insert through the wire inlet nipple over the
drive roller grooves and the guide pipe into the capillary tube and Teflon core using guide pipe.
• Press the clamping element with the pressure roller back downwards and fold the wire units back up
again (wire electrode should be in the groove on the drive roller).
• Set the contact pressure with the adjusting nuts of the pressure unit.
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.
