1 Pressure units
2 Clamping units
3 Wire feed nipple
4 Guide tube
5 Capillary tube or plastic core with support tube, depending on the torch
equipment
• Extend and lay out the torch tube package.
• Unfasten pressure units and fold out (clamping units and counter-pressure rollers will automatically flip
upwards).
• 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 counter pressure roller back downwards and fold the wire units
back up again (wire electrode should be in the groove on the drive roller).
The clamping pressure must be set on the adjusting nuts of the pressure units so that
the wire electrode is conveyed but will still slip through if the wire spool jams.
The clamping pressure for the front rollers (viewed from the direction of the feed) should always
be slightly higher than that of the rear rollers.
• Press the wire inching button until the wire electrode projects out of the welding torch.
