Feeding in the
wire electrode
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 au-
tomated 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).
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
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
CAUTION! Risk of injury and damage from the welding current and accidental ig-
nition of an arc. Before starting work, disconnect the ground earth connection be-
tween the welding system and the workpiece.
CAUTION! Risk of injury and damage from wire electrode emerging. While work-
ing:
- 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 safe-
ty 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 from springiness of spooled wire electrode. When insert-
ing the wire electrode into the 4 roller drive, hold the end of the wire electrode firm-
ly to avoid injuries caused by the wire springing back.
CAUTION! Risk of injury from moving or rotating parts in the welding system. En-
sure that all covers are closed and that all parts are fitted properly and remain in
place during operation.
