Threading the wire electrode
General
NOTE!
If there is no wire threading button on the wire-feed unit, use the wire threading
button of another of the manufacturer's system components to thread the wire, for
example the power source wire threading button.
The wire threading button functions in the same way for all system components from the
manufacturer.
NOTE!
Further details on the function of the wire threading button can be found in its
description ("Optional control panels" section, "OPT/i WF gas test & wire thread-
ing" sub-section).
Preparations
CAUTION!
Risk of injury and material damage from the welding current and accidental igni-
tion of an arc.
Before starting work, disconnect the ground earth connection between the welding sys-
tem and the workpiece.
CAUTION!
Risk of damage to the welding torch from sharp end of wire electrode.
Deburr the end of the wire electrode well before feeding in.
CAUTION!
Risk of injury from springiness of spooled wire electrode.
When inserting the wire electrode into the 4-roller drive, hold the end of the wire elec-
trode firmly to avoid injuries caused by the wire springing back.
