Input Connection
WARNING!
Only a qualified electrician should connect the input leads to the BGW-1000. Connections should be made in
accordance with all local and national electrical codes.
Connect the three phase supply line (380V for standard BGW, 240V / 440V for special version) to L1, L2, L3 and
ground to the input lug of the 3-phase circuit breaker inside the electrical cabinet as illustrated to the input supply
connection diagram below.
Connect the output of the 3-phase circuit breaker with the welding power supply input.
The electrical cabinet also consists of a step down transformer and a secondary circuit breaker for 1 phase /
220V input to the BGW. The BGWs are shipped connected for the input voltage specified for the destination of the
machine in factory.
NOTE: Turn main input power of the machine OFF before performing reconnects procedure. Failure to do so will
result in damage to the machine.
Above: non-standard input at 240V/3ph/60Hz connection.
OPERATION
After the BGW frame is securely straddled on the shell plate, extend the guide wheel to support the
weight of the frame and clear the flux belt from the tank wall for welding setup.
Adjust the flux belt surface by manual cross slide and keep it .6''-.8'' (15 – 20 mm) below the weld seam.
Adjust the torch angle and contact tip placement to the appropriate welding position.
When the weld head setup is done, retract the guide wheels assembly and allow the weight of the frame to lean
on the shell wall via the flux belt, the flux belt would be pressed tightly below the weld seam to prevent drop off the
welding flux.
Connect the weld and ground cables.
Power up the main switches at the electric cabinet, verify the weld gears and drive system are functioning.
