The best arc performance occurs when the Power
Waves have accurate data about the arc conditions.
Depending upon the process, inductance within the
electrode and work lead cables can influence the volt-
age apparent at the studs of the welder. Voltage
sense leads improve the accuracy of the arc condi-
tions and can have a dramatic effect on performance.
Sense Lead Kits (K940-10, -25 or -50) are available
for this purpose.

The ELECTRODE sense lead (67) is built into the
control cable, and is automatically enabled for all
semi-automatic processes. The WORK sense lead
(21) connects to the Power Wave at the four pin con-
nector. By default the WORK voltage is monitored at
the output stud in the POWER WAVE 405M. For more
information on the WORK sense lead (21), see ".AD=
-A>F397*7@E;@9T in the following paragraph.

For processes requiring work voltage sensing, con-
nect the (21) work voltage sense lead (K940) from the
Power Wave work sense lead receptacle to the work
piece. Attach the sense lead to the work piece as
close to the weld as practical, but not in the return cur-
rent path. Enable the work voltage sensing in the
Power Wave. (See ;B *I;F5: *7FF;@9E 3@6

Enabling or disabling electrode voltage sensing is
automatically configured through software. The 67
electrode sense lead is internal to the cable to the
wire feeder and always connected when a wire feeder
is present.

The POWER WAVE 405M and semi-automatic Power
Feed family communicate via a 5 conductor control
cable (K1543). The control cable consists of two
power leads, one twisted pair for digital communica-
tion, and one lead for voltage sensing. The cables are
designed to be connected end to end for ease of
extension. The output receptacle on the POWER
WAVE 405M is on the case front. The input receptacle
on the Power Feed is typically located at the back of
the feeder, or on the bottom of the user interface.
Due to the flexibility of the platform the configuration
may vary. The following is a general description of the
system. For specific configuration information, consult
the semi-automatic Power Feed instruction manual.

The POWER WAVE 405M and Power Feed M family of
products utilize a digital communication system called
ArcLink. Simply put, ArcLink allows large amounts of
information to be passed at very high speeds between
components (nodes) in the system. The system requires
only two wires for communication, and because of its
bus-like structure, the components may be connected to
the network in any order, thus simplifying the system set-
up.
Each "system" must contain only one power source.
The number of wire feeders is determined by the type
of wire feeder. Refer to the wire feeder instruction
manual for details
