WARNING
There are extremely dangerous voltages and
power levels present inside this product. Do
not attempt to open or repair unless you are
an Accredited Thermal Arc Service Provider.
Disconnect the Welding Power Source from
the Mains Supply Voltage before
disassembling.
An inspection of the power source, an insulation resistance
test and an earthing resistance test
shall be carried out in accordance with clause 4.1 of AS
1647.2
a) For transportable equipment, at least once every
3 months; and
b) For fixed equipment, at least once every 12 months
The owners of the equipment shall keep a suitable record
of the periodic tests.
NOTE
A transportable power source is any
equipment that is not permanently connected
and fixed in the position in which it is operated.
In addition to the above tests and specifically in relation
to the VRD fitted to this machine, the following periodic
tests should also be conducted by an accredited Thermal
Arc service provider.
If this equipment is used in a hazardous location or
environments with a high risk of electrocution then the
above tests should be carried out prior to entering this
location.
Welding equipment should be regularly checked by a
qualified electrical tradesperson to ensure that:
· The main earth wire of the electrical installation is
intact.
· Power point for the Welding Power Source is
effectively earthed and of adequate current rating.
· Plugs and cord extension sockets are correctly
wired.
· Flexible cord is of the multi-core tough rubber or
plastic sheathed type of adequate rating, correctly
connected and in good condition.
· Welding terminals are shrouded to prevent
inadvertent contact or short circuit.
· The frame of the Welding Power Source is effectively
earthed.
· Welding leads and electrode holder are in good
condition.
· The Welding Power Source is clean internally,
especially from metal filing, slag, and loose material.
If any parts are damaged for any reason,
replacement is recommended.
· The Cooling Fan should be replaced at approximately
12 months. This would depend upon the
environment used and the hours of use.
