WARNING! If the equipment is used or tasks are carried out incorrectly, serious
injury or damage may result. All the work described below must only be carried
out by trained and qualified personnel. Do not carry out any of the work described
below until you have fully read and understood the following documents:
- these operating instructions
- all the operating instructions for the system components, especially the safe-
ty rules
CAUTION! The power sources must be switched on for the following work. This
poses a risk of injury and material damage due to:
- welding current
- unintentional ignition of an arc
- emerging wire electrodes
Until all work is completed, ensure that:
- welding is not initiated by any power source
- the wire electrodes are not fed out
NOTE! Optimum welding results are only achieved up to a welding circuit induc-
tivity of 30 μH (at a mains voltage of 400 V). Welding circuit inductivity in excess
of 30 μH must be reduced.
The following measures may be taken to reduce welding circuit inductivity:
- Keep the torch hosepack, interconnecting hosepack and earthing cable as
short as possible
- Lay the torch hosepack, interconnecting hosepack and earthing cable paral-
lel to each other
