SYSTEM DESCRIPTION
The POWER WAVE 355 and Power Feed family of
wire feeder products utilize a digital communication
system called Linc-Net. Simply put, Linc-Net allows
large amounts of information to be passed at very
high speeds between components (nodes) in the sys-
tem. The system requires only two wires for communi-
cation, and because of its bus-like structure, the com-
ponents may be connected to the network in any
order, thus simplifying the system set-up.
Each "system" must contain only one power source.
The power source may be connected to a maximum
of four feeder groups. Each group containing one
user interface (UI), and up to seven Feed Heads
(FH). SEE FIGURE A.1. The UI controls all of the
FH's of that group. The UI's and FH's are assigned to
groups by setting a code on the DIP switches mount-
ed on their individual control boards. For example all
of the FH's to be controlled by a given UI must have
their "Group ID" switches set to the same group num-
ber as the UI. In addition, each FH must be assigned
a separate FH number within that group. See the sys-
tem set-up section for further details.
System Model
INSTALLATION
From a network perspective, each component in the
system is considered a separate node, regardless of
its physical location. For example, even though a UI
and FH may be physically mounted together, they are
still viewed as separate pieces (nodes) by the net-
work, and can only communicate via Linc-Net. The
Linc-Net connection is generally made external
through the Linc-Net Control Cable, but can also be
made internally, as with the Power Feed 10 bench
model feeder.
The most common Linc-Net configuration (called a
simple system) consists of one power source, one
user interface and one feeder. Under these circum-
stances the group and feed head ID DIP switches are
ignored and the system will function regardless of
their position. The same is true for the minimum sys-
tem consisting of a power source and one UI
(Example: a stick welding system).
