Feeding in the wire electrode
Insulated routing
of wire electrode
to wire-feed unit
WARNING!
Risk of serious injury and property 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 wirefeeder spool or wirespool to the wirefeeder (e.g.
by using a wirefeeding hose).
An earth contact or short-circuit can be caused by:
-
an uninsulated, exposed length of wire electrode coming into contact with an electri
-
cally conductive object during welding
-
missing insulation between the wire electrode and the earthed enclosure of a robot cell
-
chafed wirefeeding hoses, exposing the wire electrode
Using wirefeeding hoses ensures that the wire electrode remains insulated as it is trans
-
ported towards the wirefeeder. To prevent chafing, do not route the wirefeeding hoses over
sharp edges. Use hose holders or hose protectors as necessary. Coupling pieces and
hoods for welding wire drums also ensure safe transport of the wire electrode.
Safety
WARNING!
Danger from incorrect operation.
Operating the equipment incorrectly can cause serious injury and damage.
► Before putting the unit into service for the first time, read the "Safety rules"
CAUTION!
Risk of injury while the lid is open for maintenance or retooling work to be carried
out.
Work that is carried out incorrectly can cause serious injury or damage.
► Ensure that there is no risk of anybody accidentally starting up the VR 1530‘s drive
components by pressing the feeder inching button(s) on the control panel, on the VR
1530 itself or on any other system add-ons.
Preparations
Fit the wirefeeding hose from the unreeling device or from the welding wire drum to
the VR 1530
Fit the wirefeeding hose from the VR 1530 to the VR 1500
Feeding in the
welding wire
CAUTION!
Risk of injury from the spring effect of the coiled welding wire.
This can result in serious injury and damage to property.
► When threading in the wire, hold the end of the wire firmly, to prevent any injuries that
might be caused by the wire flicking back and recoiling uncontrollably.
