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 stabilising
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.
Despite their robustness, this welding source requires some regular maintenance. Each 3 months or 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 condition, 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 portable 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.
7.1 - REPAIR
POSSIBLE CAUSES
YELLOW AND GREEN LED INDICATOR OFF = NO SUPPLY
ON/OFF main switch is OFF
Power supply cable is interrupted
No main supply
Defective ON/OFF main switch
YELLOW INDICATOR ON = INPUT VOLTAGE OVERRATED LIMIT
Input voltage ± 10%
Duty cycle overrated (if ambient > 25°C)
Insufficient cooling air
Very dusty machine
Fan doesn't start
IMPROPER WELDING
Wrong electrode polarity
Dirtiness in the weld parts
Improper electrode
Important notice:
This equipment must be installed, operated or maintained only by qualified persons. Never start up this machine
without his casing. Before open, disconnect from the main's supply.
CHECK
Switch it ON
Check cable and connections
Check circuit breaker and fuses
Replace the switch
Check supply voltage; connect machine to a proper
voltage supply (230V± 10%)
Let the machine cool, it will automatically start again
Clean the air inlets
Open and clean the machine
Check connections or replace the fan
Use the right polarity according to the electrode's
manufacturer
Clean and eventually degrease the parts to be welded
Check electrode compatibility and warm it up if possible
