7.2.3 Prevent over-voltage
The welding voltage within the circuit will automatically compensate to ensure
the welding current is in the permitted range. If the voltage exceeds the
allowable value it can damage the machine. The welder should be fully aware of
this and take appropriate preventive measures.
7.2.4 The DIGI-ARC 200 LT is supplied with an earth screw and marked with earth
markers. Before operation, use a larger than 2.5mm cable in the welding
chassis to earth any static electricity or to prevent accidental leakage.
7.2.5 If the welding work exceeds the standard loading time, the welding machine
may suddenly cut out due to over-heating. This triggers a temperature control
switch and the front panel alarm indicator lights up. Do not unplug the power
to maintain cooling fan rotation. The red light goes out when the temperature
has dropped to a safe level and welding can recommence.
8 MAINTENANCE
The following operations require the welder has sufficient electrical expertise and can
demonstrate a comprehensive knowledge of working safely with valid qualifications and
documents. Check to make sure the welding power input cable is not broken.
8.1 Periodically inspect the internal circuit connections are intact and reliable (especially
the joints or components). If any rust and debris is found, sand off, clean, reconnect
and tighten.
8.2 Do not allow hands, hair and tools near live components or fans inside the machine.
8.3 Regularly clean machine with dry compressed air. Compressed air pressure should be
at a reasonable level in order to avoid damage to the welding of small internal
components. Dust the machine regurlarly.
8.4 Avoid water or water vapour getting inside the welding machine inside. In the event of
accidental ingress, the machine should be thoroughly dried. Only when you are sure
that any moisture or water has been thoroughly dried from inside may you use the
machine. Suitable tools for checking the moisture content within are advised.
8.5 Regularly inspect the cable insulation for damage. In the event of any damage wrap or
replace the cable.
8.6 When not using the machine, place back in the case and keep in a dry environment.
