Weld Head Assembly
The BGW weld head is mounted on a manual cross slide system,
which allows the operator complete control of wire placement and
joint tracking.
Due to the lack of visibility of the submerged arc welding process, a
laser pointer is mounted on the nozzle to provide a position reference
for operator while welding.
Control
Welding Control
The Lincoln USA NA3 welding control is normally supplied with the
girth welder. It is mounted on the right hand side of the main frame for
the operator to access easily. Directly on top of the NA3 control is the
BGW master control.
Master Control
The BGW master control houses the electronic travel inverter drive
and associated control relays; it provides a mean of integrated control
of all the accessories of the girth welder (eg. flux vacuum, 220V single
phase aux outlet, lamp, flux winch).
The control panel includes all necessary control knobs and switches
such as the speed control potentiometer, direction switch, full speed
travel switch as well as emergency stop button.
110V Aux Version Control System
The Bug-o All Time BGW sold in the markets using 110V are equipped
with a special circuitry to provide 110V aux outlet and lamps. The 110V
outlet socket is identified with yellow color instead of blue as in the
standard 220V aux power outlet.
