Feeding in the wire electrode
Insulated rout-
ing of wire elec-
trode 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 wirefeeder (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
conductive 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 en-
sure 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 system 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.
