Inching the wire electrode

Risk of injury due to welding wire escaping from the welding torch!
The welding wire can escape from the welding torch at high speed and cause bodily in-
jury including injuries to the face and eyes!
• Never direct the welding torch towards your own body or towards other persons!
The inching speed is infinitely adjustable by simultaneously pressing the wire inching push-
button and turning the wire speed rotary knob. The left display shows the wire feed speed
selected, the right display shows the current motor current of the wire feed mechanism.
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!

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.
• Press the wire inching button until the wire electrode projects out of the welding torch.
