Periodically and as frequently as required by the use and environmental conditions,
inspect inside the spot welder and clamp and remove the dust and metal particles that
have deposited on the transformer, diode module, power terminal board, etc. using a

- Make sure the screws that connect the transformer secondary with the output bars
In case of:
- liquid leaks;
you should proceed to check for any problems inside the cooling unit.
Always refer to section 7.2 for overall warnings and however having disconnected the
spot welding machine from the power supply mains, proceed with removing the side
panel (FIG. L).
Check there are no leaks both on connections and tubing. If liquid is leaking, replace
the damaged part. Eliminate the liquid residue possibly leaked during maintenance
and close the side panel again.
Then proceed to reset the spot welding machine using the appropriate information

- The welding parameters are suitable for the work to be carried out
- After having carried out maintenance or repairs, restore the connections and wiring
as they were before, making sure they do not come into contact with moving parts
or parts that can reach high temperatures. Band all the wires as they were before,
being careful to keep the primary high voltage connections separate from the
secondary low voltage ones.
Use all the original washers and screws when re-closing the structural work.
