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
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 con-
ductive 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
Safety
CAUTION!
Risk of injury by rotating drive components if the cover is opened for maintenance
or set-up work.
Make sure that the drive components of the unreeling wire-feed unit cannot be started at
the power source, the unreeling wire-feed unit itself or other system add-ons.
CAUTION!
Risk of damage to wirefeeding hose and welding torch from sharp end of wire
electrode.
Deburr the end of the wire electrode well before feeding in.
CAUTION!
Risk of injury from springiness of spooled wire electrode.
When inserting the wire electrode into the wirefeeding hose, hold the end of the wire
electrode firmly to avoid injuries caused by the wire springing back.
Feeding in the
wire electrode
1
Connect the mains cable of the unreeling wirefeeder to the mains
2
Switch on mains switch
The green mains supply LED flashes rapidly, then the mains supply and wire thread-
ing mode LEDs light up green.
Wire threading mode is activated.
