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 de-
scription ("Optional control panels" section, "OPT/i WF gas test & wire threading"
sub-section).
Preparatory work
CAUTION!
Danger from welding current and accidental ignition of an arc.
This can result in severe personal injury and damage to property.
▶
Before starting work, disconnect the ground earth connection between the welding
system and the workpiece.
CAUTION!
Danger from sharp end of wire electrode.
This can result in severe personal injury and damage to property.
▶
Deburr the end of the wire electrode well before threading in.
CAUTION!
Danger from elasticity of the spooled wire electrode.
This can result in severe personal injury and damage to property.
▶
When inserting the wire electrode into the 4-roller drive, hold the end of the wire
electrode firmly to avoid injuries caused by the wire springing back.
