- With the main switch of the spot welder closed (pos. “ I “) the display is lit; if not
the problem is in the power line (cables, plug and socket, fuses, excessive voltage
drop, etc.).
- The display does not show the alarm signals (see TAB. 1): when the alarm stops
press “START” to reactivate the spot welder.
- The elements that are part of the secondary circuit (gun - cables) are not inefficient
because of loose screws or oxidation.
- 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.
