General: The Weldanpower 230+ is a single phase 50/55 Hz.
auxiliary power generator with a total maximum output of 8kVA-
8000 watts at unity power factor, or 6400 watts at 0.8 power
factor. It is suitable for long term primary power, and temporary
standby, or emergency power, using engine manufacturer's
recommended maintenance schedule.
Start the engine and allow it to warm up. Voltage is now at the
receptacles for auxiliary power.
The total auxiliary power output capability is available when the
"output control" is set at "10".
The current rating of any plug used must be at least equal to the
current load through the associated receptacle. Do not attempt
to connect power receptacles in parallel.
When using the 240 volt auxiliary power, each single receptacle
has a maximum rating of 15 amps. The total current that can be
drawn from all three receptacles at one time is 33 amps.
Most 1 kW motors can be started if there is no load on the motor
or other load connected to the Weldanpower, since the full load
current rating of a 240 volt, 1 kW motor is approximately 10
amperes. The motor may be run at full load when plugged into
one of the receptacles. Larger motors up to 1.5 kW can be run
provided the receptacle rating as previously stated is not
exceeded.
The above auxiliary power rating is with no welding load.
Simultaneous welding and power loads are permitted by following
the Table below. The permissible currents assume that the fine
output control is set at 10. A lower setting of the fine output control
will decrease the available auxiliary power.
Short circuit protection of the auxiliary power circuits is provided
by three 15 amp circuit breakers.

Connection of appliances
In line with current practice, a floating auxiliary power system is
used.
Machines with three pin outlets for auxiliary supply have, at each
outlet, isolated active and neutral sockets and an earth socket.
Only the earth socket is bonded to the frame of the machine and
earth leakage protection is not required (refer AS2790-1989, CI.6-
1.9(a) and Comment 1).
For your safety, all auxiliary equipment, extension cords,
appliance cords, plugs, plug sockets, and appliances should be in
good condition and correctly wired and connected. All earthing
wires, where used, must be continuous. Extension cords with
three wires should be used except for double insulated
appliances.
The frame of the unit should not be connected to the general
mass of earth by an earth spike or by any other means, but should
be isolated from earth.
Connection for use as a standby power unit
The Weldanpower 230+ may be permanently, or temporarily,
installed as a stand by power unit for a 240 volt. 50/55 Hz. AC
supply.
To avoid the possibility of electric shock and /or damage to the
welding machine or connected apparatus, all connections and
alterations must be made by a licensed electrician, who can
determine how the machine should be adapted to the particular
installation so as to comply with the local Supply Authority
regulations and any relevant requirements.
It is important than an adequately rated and properly connected
isolation switch be used to ensure that the Weldanpower and the
Authority's supply cannot be connected in parallel.
