Insulated Guiding
of the Wire Elec -
trode to the Wire -
feeder
WARNING!
Risk of injury and property damage, as well as impairment of the welding result, due
to ground fault or earth leakage of a non-insulated wire electrode.
► In automated applications, only guide the wire electrode from the welding wire drum,
large spool or wirespool to the wirefeeder with insulation (for example using a wirefeed -
ing hose).
A ground fault or earth leakage can be caused by:
- a non-insulated, exposed wire electrode, that comes into contact with an electrically
conductive object during the welding process
- a lack of insulation between the wire electrode and the grounded housing limit of a ro -
bot cell
- chafed wirefeeding hose and therefore bare wire electrodes
In order to avoid ground faults or earth leakage:
- use wirefeeding hoses—for insulated guidance of the wire electrode to the wirefeeder
- do not guide wirefeeding hoses over sharp edges in order to avoid chafing of the wire -
feeding hoses
- if necessary, use a hose holder or chafe protector
- Couplings and drum covers for welding wire drums are also recommended in order to
ensure safe transport of the wire electrode
