7. MAINTENANCE

This arc welding equipment should be routinely maintained according to the manufacturers' recommendations. All
access and service doors and covers should be closed and properly fastened when the arc welding equipment is in operation.
The arc welding equipment should not be modified in any way, except for those changes and adjustments covered in the
manufacturer's instructions. In particular, the spark gaps of arc striking and stabilizing devices should be adjusted and
maintained according to the manufacturer's recommendations.
Before carrying out any internal checking or repair work, check that the power source has been disconnected from the
electrical installation by locking and guard devices. Ensure and avoid accidental connection of the plug to a socket. Voltages
are high and dangerous inside the machine.
In spite of their robustness, ours power sources require some regular maintenance. Each 6 months (more often in
dusty surroundings):
- The machine must be blown through with dry, oil free compressed air.
- Check for continuity all electrical connections.
- Check the connection of cables and flat top.
Check the good state, insulation and connection of all the equipment and electrical accessories: plugs and flexible
supply cables, conduits, connectors, extension cables, sockets on the power source, ground clamp and electrode holder. These
connections and mobile accessories are marked according to standards, if consistent with the safety rules. They can either be
controlled by you or by accredited firms.
-Repair or replace all defective accessories
-Check periodically that the electrical connections are tightened and do not heat.
Maintenance works of electrical equipment must be entrusted by qualified people (Section VI, Art. 46).
7.1 DAMMAGE REPAIR
POSSIBLE CAUSES
YELLOW AND RED INDICATORS ARE OFF = NO SUPPLY
ON/OFF main switch is OFF
Power supply cable is cut
No main supply
Defective ON/OFF main switch
YELLOW AND RED INDICATORS ON = INPUT VOLTAGE OVER RATED LIMIT
Incorrect input voltage
Power source connected to 1 phase
YELLOW INDICATOR ON = WARMING UP
Duty cycle over rated (if ambient > 25°C)
Insufficient cooling air
Very dusty machine
Fan doesn't start
IMPROPER WELDING
Wrong electrode polarity
Dirtiness in the weld parts

CHECK
Switch it ON
Check cable and connections
Check circuit breaker and fuses
Replace the switch
Check supply voltage
Connect the machine to proper voltage (3x400V)
Let the machine cool, it will automatically start again
Clean the air inlets
Open the generator and blow it through
Replace the fan
Use the right polarity according to the indications of
electrode's manufacturer
Clean and eventually degrease the weld parts
