3.7.1 Load
Load according to the stipulated parameters. For the electric principle diagram of
the welder and generator set, please see the following figure.

3.7.2 Welder and Generator Output
(1) Be sure that the revolution speed of the welder and generator set be
increased to the rated speed (the speed handle of the diesel engine should be
turned to the top.). Otherwise the automatic voltage adjustment device will
produce the forced excitation. If the running is for a long time under such
condition and AVR will be burned out. For the rated revolution speed of the
generator, please see 1.1. Main Technical Specifications and Data in Chapter 1.
(2) After switching on the air switch, observe the voltmeter on the panel of the
control cabinet and the voltmeter should point to 230V 5% (50Hz),(for 60Hz set,
point to 240 V 5%). At the same time, set the selection switch to GEN
(generation) position. At this time, the AC power supply is supplied from the
power supply socket.
Do not start more than two machines at the same time.
CAUTION
The machines should be started one by one. Do not
use the floodlight at the same time of using other
machines.

The revolution speed of the generator (50Hz) should be increased up to the rated
speed 3000r/min (the speed handle should be turned to the top.).
(3)At the time of connecting with the generator, all kinds of equipment should be
connected in order. For the matter of the motor load, firstly the large power
motors should be connected. After the operation is normal, then the small power
motors can be connected. If the operation is incorrect, the generator will cause
the running hysteresis or will brake suddenly. It is necessary to unload the load
immediately and to turn off the generator switch. Check where the trouble
appears.
If the circuit overload makes that the air switch of AC circuit trips, it is necessary
to reduce the circuit load. It is not allowed that the set runs under the overload
condition. Maximum output power of the generation for the set should not exceed
the stipulation in Table 1-1. It is necessary to wait for several minutes before
restoring the operation. If the indication on the voltmeter is too low or too high, the
revolution speed can be adjusted. If there is any trouble and any abnormal
running condition, it is necessary to stop the generator for check.
(4) When the selection switch is set onto GEN, the switch is used for the
generation output.
At this time, there is also the welder voltage output at the welder output terminals.
But the output current is smaller, which can be used only for the electric welding
rods below 3.2mm. The welding current to be selected can be only below 130A.
While welding, the load attached at the generation output side should not exceed
1 kW. In such a way, it is possible to ensure a bigger welding current. The set will
supply only the essential illumination at the welding time to avoid the overload.
(5) When the selection switch is set to WELD (welding), the set will supply the
welding output (at this time, there is no voltage output from the generation socket.).
According to the electric welding rods or the operation demand, the current can
be adjusted through the potentiometer knob on the switching board. By adjusting
to a suitable position, the welding can be carried out. If a smaller current is
needed, it is possible to reduce the not be used for a long time. The position for
the rated current is one marks less than maximum position, the rate welding
current is 160A.
(6) Before using the set. It is necessary to firmly connect the welding cable joints
with the wiring terminals and so as to avoid burning out the terminals because of
poor connection.
(7) While the set is in operation, it is necessary to keep good ventilation. The
welder and generator set should not be covered with foreign matter to prevent the
matter from hindering the heat dissipation.
