5.2.2.3 Inching the wire electrode
CAUTION
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!
Improper contact pressure increases wear on the wire feed rolls.
Adjust the contact pressure on the adjusting nuts of the feed roll tensioners so that the wire
electrode is fed but slips when the wire spool is blocked.
The inching speed is infinitely adjustable by simultaneously pressing the wire inching push-
button and turning the wire speed rotary knob.
