3.4 - EARTHING

- To ensure user protection the welding machine must absolutely be correctly connect-
ed to the earth system (INTERNATIONAL SAFETY REGULATIONS).
- It is indispensable to provide good earthing by means of the yellow-green lead in the
power cable, in order to avoid discharges due to accidental contacts with earthed ob-
jects.
- The chassis (which is conductive) is electrically connected with the earth lead; if the
equipment is not suitably connected to earth it may cause electric shocks which are
dangerous for the user.
