Feeding in the wire electrode
Insulated routing
of wire electrode
to wire-feed unit
WARNING!
Risk of serious injury and material 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 wire-feed unit spool or wirespool to the wire-feed unit
(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 wire-feed unit
- Prevent chafing by not routing 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 from springiness of spooled wire electrode.
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.
Deburr the end of the wire electrode well before feeding in.
