Feeding in the wire electrode
Insulated routing 
of wire electrode 
to wirefeeder
WARNING!
Risk of serious injury and 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 wirefeed-
er (e.g. by using a wirefeeding hose).
An earth contact or short-circuit can be caused by:
- a non-insulated, exposed length of wire electrode coming into contact with a conduc-
tive object during the welding process
- missing insulation between the wire electrode and the earthed enclosure of a robot cell
- chafed wirefeeding hoses, exposing the wire electrode
To avoid earth contact or short-circuit:
- Use wirefeeding hoses for insulated routing of wire electrode to wirefeeder
- To prevent chafing, do not route the wirefeeding hoses over sharp edges
- Use hose holders or hose protectors where necessary
- Coupling pieces and hoods for welding wire drums are recommended to ensure safe 
transport of the wire electrode 
Feeding in the 
wire electrode
CAUTION!
Risk of injury and damage from the welding current and accidental ignition of an arc.
► Before starting work, disconnect the ground earth connection between the welding sys-
tem and the workpiece.
CAUTION!
Risk of injury and damage from wire electrode emerging.
While working:
► Hold the welding torch with the end directed away from the face and body
► Wear suitable protective goggles
► Do not point the welding torch at people
► Make sure that the wire electrode does not touch any conductive or earthed parts (e.g. 
housing)
► Ensure that all covers are closed, all side panels are in place and that all safety devices 
are intact and in their proper place (e.g. protection devices).
CAUTION!
Risk of damage to the welding torch from sharp end of wire electrode.
► Deburr the end of the wire electrode well before threading in.
CAUTION!
Risk of injury due to 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.
