Once the main frame is setup correctly, mount the cable
hanger (1), safety hand rail (2), flux lifting post (3)
and electric flux winch (4), on the frame roof.
Mount the NA-3 control and master control to the control
mounting plate at the right hand side of the frame.
Master Control Connections
There are nine sets of receptacles (eight sets for some
models) at the side of the control panel, each receptacle is
DIFFERENT and only can mate with the correct connectors
of the below components:
a)
Flux Vacuum
b)
Main power
c)
110 or 220VAC/1ph aux output (for electrical hand tools
such as a grinder)
d)
Laser pointer
e)
Lighting
f)
NA3 on/off
g)
Dual motor drive
h)
Flux lifting winch
i)
Cooling fan
Installation
When all components of the BGW are in place, hook up the
lifting eye at the roof of the BGW with a crane and lift the
frame off the ground, then hang drive wheels on top of the
plate wall and lower it down, so the flanged wheel lands on
top of the shell plate.
Note: For double sided unit (BGWII), operator is required to expand the hydraulic jack above the opera-
tor platform to “open up” the hinged master and slave frame, allowing the opened “A” frame of the
double sided unit to straddle on the shell plate.
While loading, the angle between the lifting cable and the horizon
should not be greater than 60°.
The guide wheels should be extended to the maximum extension
with the hand wheel, and then bolted at the position perpendicular to
the ground surface, it provides a moving support to the frame and
prevents impact between the flux belt systems and the weld head to
the shell plate.
When the BGW frame is secured, straddle on the shell plate, retract
the support guide wheel by the hand wheel and bolt the orientation of
the support wheel to the horizontal position.
The weight of the BGW frame should then be supported by the flanged
metal wheels at the top as well as the flux belt assembly.
The welding power supply is intended to be located on the floor in the center of the storage tank. All of the cables
are run from the power supply to the cable hanger at the roof of the machine frame.
All cable connections are made at this point and the hanger clamp fastened in a way that the connections them-
selves do not feel the strain of the cable weight.
Locate the power supply storage near the center of the tank. The storage case contains the main power distribu-
tion disconnect, distribution transformer, and the welding power supply.
