Feeding in the wire electrode
Insulated routing
of wire electrode
to wire-feed unit
Risk of serious injury and property damage or an inferior weld as a result of earth
contact or short-circuit of a non-insulated wire electrode.
In the case of automated applications, ensure that only an insulated wire electrode is rout-
ed from the welding wire drum, large wirefeeder spool or wirespool to the wirefeeder (e.g.
by using a wirefeeding hose).
An earth contact or short-circuit can be caused by:
-
-
-
Using wirefeeding hoses ensures that the wire electrode remains insulated as it is trans-
ported towards the wirefeeder. To prevent chafing, do not route the wirefeeding hoses over
sharp edges. Use hose holders or hose protectors as necessary. Coupling pieces and
hoods for welding wire drums also ensure safe transport of the wire electrode.
Feeding in the
wire electrode
Risk of injury due to elasticity of spooled wire electrode.
It can cause injuries.
► When inching in the wire electrode into the 4-roll drive, hold the end of the wire elec-
Danger from sharp end of wire electrode.
This can result in damage to the welding torch.
► Deburr the end of the welding wire thoroughly before feeding in.

WARNING!
an uninsulated, exposed length of wire electrode coming into contact with an electri-
cally conductive object during welding
missing insulation between the wire electrode and the earthed enclosure of a robot cell
chafed wirefeeding hoses, exposing the wire electrode
CAUTION!
trode firmly to avoid injury from wire electrode lash back.
