- Disconnect the load before switching off the motor.
- If the AC outlets are overloaded or if the connected equipment
malfunctions, the thermostatic safeguards cut in (Fig. B-17 or
B-18).
- Reset is not automatic. To reset the system (RESET) the
thermostatic safeguard MUST be re-activated.
It is forbidden and dangerous to connect the machine
and power the electric network of a building.
8. MAINTENANCE
WARNING! BEFORE CARRYING OUT MAINTENANCE
WORK, MAKE SURE THE ENGINE-DRIVEN WELDING MACHINE
IS SWITCHED OFF.
ROUTINE MAINTENANCE
ROUTINE MAINTENANCE WORK CAN BE DONE BY THE
OPERATOR.
INTERNAL COMBUSTION ENGINE MAINTENANCE
Carry out the checks and programmed maintenance indicated in
the USER MANUAL of the internal combustion engine producer.
The discharge pump (Fig. N) can be used to change the oil.
EXTRAORDINARY MAINTENANCE
EXTRAORDINARY MAINTENANCE MUST ONLY BE CARRIED
OUT BY TECHNICIANS WHO ARE EXPERT OR QUALIFIED IN
THE ELECTRIC-MECHANICAL FIELD, AND IN FULL RESPECT
OF THE IEC/EN 60974-4 TECHNICAL DIRECTIVE.
WARNING! BEFORE REMOVING THE ENGINE-DRIVEN
WELDING MACHINE PANELS AND ACCESSING IT, MAKE SURE
IT IS SWITCHED OFF.
If checks are carried out while the inside of the engine-driven
welding machine is live this could cause serious electric shock
due to direct contact with live parts and/or injury due to direct
contact with moving parts.
- Make regular checks at intervals that depend on the use and on the
amount of dust in the environment, inspecting inside the engine-
driven welding machine and removing any dust deposited on the
alternator and on the reactance coil using a jet of dry compressed
air (max. 10bar).
- Take the opportunity to make sure there are no loose electrical
connections and that the wiring insulation has not been damaged.
- After completing these operations, re-assemble the engine-driven
welding machine panels, tightly fastening the screws.
- Never ever carry out welding operations if the engine-driven
welding machine is open.
- 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. Tie 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.
9. ENGINE-DRIVEN WELDING MACHINE TRANSPORT AND
WINTER STORAGE
Regarding engine-driven welding machine transport and winter
maintenance, refer to the USER MANUAL of the internal combustion
engine producer.
10. TROUBLESHOOTING
IF THE WELDING MACHINE IS NOT WORKING PROPERLY,
BEFORE MAKING MORE SYSTEMATIC CHECKS OR CALLING
YOUR SERVICING CENTRE MAKE THAT:
- The welding current is suitable for the diameter and type of
electrode to be used.
- You have not exceeded the rated duty cycle; if the thermal cutout
has triggered wait until the engine-driven welding machine has
cooled naturally, make sure the fan is working properly.
- There is no shorting at engine-driven welding machine output: in
such a case eliminate the problem.
- The welding circuit connections have been made correctly, in
particular that the earth clamp is actually connected to the piece,
with no insulating material (e.g. paint) in the way.
As far as troubleshooting for the engine is concerned, refer to
the USER MANUAL of the internal combustion engine producer.
Refer to the nearest engine retailer should problems with the
internal combustion engine occur.
