Feeding in the wire electrode
Insulated routing
of wire electrode
to wire-feed unit
WARNING!
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
routed 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:
-
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
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.

CAUTION!
Risk of injury from springiness of spooled wire electrode.
This can result in serious 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.
CAUTION!
Risk of damage to the welding torch from sharp end of wire electrode.
This can result in serious damage to property.
▶
Deburr the end of the wire electrode well before feeding in.
