Fitting wirefeeding hose for external wire electrode
General The wirefeeding hose option serves to protect the external wire electrode while it is being
conveyed to the 4 roller drive of the wirefeeder.
The wirefeeding hose is available in two versions:
- for steel (blue)
- for aluminium (white)

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 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:
- 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.
