opens, providing an air pressure signal to the
head unloader valves of the compressor.
This causes the air in the compressor to vent
to the atmosphere.
When the air tank pressure falls below 95
psi, the pilot valve will close, stopping the air
signal to the unload valves, allowing the
compressor to start pumping air to the tank.
A lever on the top of the pilot valve will allow
the operator to manually stop the
compression of air by the compressor during
initial engine start-up or if operation does not
require the use of compressed air
(
Figure 4-4
). Since the head unloader valves
require air pressure to operate, there must
be a minimum of 10 psi in the air tank to
allow the valves to operate properly.
When purchasing air tools or planning a
project, the rated capacity of the compressor
(20 CFM @ 100 psi) will need to be taken
into consideration. Check the desired power
tool manufacturer’s specifications to ensure
that the tool capacity is within range of the
compressor’s operating scope.
4.9 OPERATING THE
(OPTIONAL) BATTERY
CHARGER FOR STAND-
ALONE SYSTEMS
Your Air-N-Arc 150 Series machine also
supports an optional Battery Charger for
boosting/charging batteries. This option is
offered in 12 VDC or 24 VDC configurations.
The battery charge options have been
factory set at 15.3 VDC for the 12V option or
27.3V for the 24V option. Both have a
maximum output of 150 Amps.
These settings may be adjusted, but only by
a certified technician. If you have the need
for these settings to be changed, please call
Vanair Service Support at 844-VAN-SERV
(844-826-7378).
4.9.1 CONNECTION - DISCONNECTION
SEQUENCE AND OPERATION
1. Disconnect the battery from the
equipment system so that it is
completely isolated.
NOTE
The leading cause of component failure
of the air control system is moisture. Air
tanks must be drained daily as a
minimum to eliminate condensation.
WARNING
NEVER disconnect boosting
connections or cables while charging /
boosting. This will cause a voltage spike
on the machine. Failure to follow this
warning can result in injury, and/or
damage or failure of any or all electronic
components, thus voiding the warranty
of the machine.
WARNING
ALWAYS wear a face-shield when
connecting or disconnecting battery
charging cables and always follow the
connection and disconnection sequence.
Electrical sparks can cause a battery to
explode, resulting in serious injury.
IMPORTANT
To prevent damaging voltage spikes, the
battery cables must be disconnected
from the battery to be charged in any
vehicle equipped with a computer, or any
equipment with sensitive electronic
components. Failure to follow this
warning can result in damage or failure
of any or all electronic components, thus
voiding the warranty of the machine.
IMPORTANT
The welder switch on the control panel
controls the battery charging system.
