Inching the wire electrode
To ensure optimum wire feeding, it is essential that the wire feed rollers match the applied wire
electrode diameter and the type of material used (exchange if necessary).
Slide new drive rollers into place so that the diameter of the wire electrode printed on the wire
feed roller is visible. Screw the drive rollers in place with knurled screws.

• 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-roller back downwards and fold the wire units back up
again (wire electrode should 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.
• Press the wire inching button until the wire electrode projects from the welding torch.
For wire feed units with control M3.70, the inching process is started directly on the control by
pressing the
key button.
The inching speed can be selected in two stages (ramp function), see also chap. Function
specification / special parameters.
Caution, risk of injury!
Never point welding torch at people or animals!
