STATUS

CONTROL BOX

(USER INTERFACE)
BOOM MODELS ONLY
The system Control Box is the main entry point for all
system parameters, and from it the user can control
both power source and wire feeder funcions. Refer to
figure E.10. The user interface motherboard is the
heart of the Control Box. Dependent upon the option
panels and the information received through the net-
work cable, it directs the entire system as to the
options, wire feed speed, and weld cycle requirements
and parameters.
The options are divided into two physical size cate-
gories. The smaller option, typically installed in the
middle section of the control box, is dedicated to dual
procedure, head selection, and memory related func-
tions. The larger, or bottom section, is reserved for
control of the setup functions for the power source
(Power Wave 455m) and wire drive (Power Feeder
10m) such as mode, arc control, run in and timer set
up.

OPTIONS
In addition to the large and smaller size options, there
is a Display Panel which is standard on the Control
Box unit. The Display Panel is typically installed in the
upper position of the Control Box assembly and the
STATUS LED. The controls are used to adjust the wire
feed speed, current, voltage and trim parameters. The
SATUS LED is designed to blink a red and green code
if a fault should occur.
The PF-10M single bench and the PF-10M dual bench
do not have User Interface Boards in the control box.
On these models the User Interface Bd circuitry is on
the feed head Bd located in the wire drive box.
