DAW-500S — INSTRUMENTATION
Power Outlets
The welder/AC generator has the following single-phase 60
Hz, 120 volt receptacles.
Single Phase
One Duplex NEMA (GFCI) 5-20R (120V, 20 Amp)
One Twist Lock NEMA L5-30R (120V, 30 Amp)
Main Circuit Breaker (Single-Pole)
This single-pole, 25 amp breaker protects the welder/AC
generator from short circuiting or overloading from the 60
Hz single-phase load.
GFCI Protection Breaker (Single-Pole)
This single-pole, 20 amp breaker protects the GFCI
receptacle from short circuiting or overloading.
CAUTION :
When using a combination of dual
receptacles, total load should not exceed
the rated capacity of the welder/AC
generator set.
Idle Control Switch
The DAW-500S Welder/AC generator is provided with an
automatic idle (engine) control capability for noise
suppression and fuel cost reduction. The automatic idle
control feature automatically engages under a no-load
condition.
When the Idle Control Switch is placed in the “ON” position,
the engine revolutions will be approximately 2000 rpm (low-
speed operation). When a load is connected to one of the
output receptacles, the engine speed will a u t o m a t i c a l l y
increase to about 2800 rpm (high-speed operation) within 10
seconds. Conversely, when the load is removed, the engine
speed will automatically drop back down to 2000 rpm within
10 seconds.
With AC loads of more than 150W (such as lighting
equipment, motor-powered tools, submersible water pumps,
etc.), the engine runs at high speed. When a no load condition
is produced, the engine automatically slows down.
Turn the idle control switch to the “ON” (up) position when
AC loads of more than 200W are connected. Turn the idle
control switch to the “OFF” (down) position when AC loads
of less than 100W or when a magnetic switch is used, or if
very high quality of welding result is required.
However, when welding in CV Low, the engine will continue
to run at a low speed, even when appling AC loads.
GFCI Receptacle
Before connecting a load to the generator's GFCI receptacle,
push
the "Test Button" on the front of receptacle before
connecting the load, to confirm that the receptacle is
functioning correctly.
