Inching The Wire Electrode - EWM Drive XQ AC Operating Instructions Manual

5.3.3.3

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
injury including injuries to the face and eyes!
• Never direct the welding torch towards your own body or towards other persons!
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 electro-
de 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!
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.
Depending on the design of the device, the wire feed mechanism may be reversed!
