Work Voltage Sensing
The standard Power Wave 455M's default to the work
stud (work sense lead disabled)
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 as follows:
WARNING
1. Turn off power to the power source at the discon-
nect switch.
2. Remove the front cover from the power source.
3. The control board is on the left side of
the power source. Locate the 8-position
DIP switch and look for switch 8 of the
DIP switch.
4. Using a pencil or other small object,
slide the switch right to the OFF posi-
tion if the work sense lead is NOT con-
nected. Conversely, slide the switch to
the ON position if the work sense lead
is present.
5. Replace the cover and screws. The PC board will
"read" the switch at power up, and configure the
work voltage sense lead appropriately.

POWER WAVE 455M
Electrode Voltage Sensing
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.
Important: The electrode polarity must be config-
ured at the feed head for all semi-automatic
processes. Failure to do so may result in extreme-
ly high welding outputs.

POWER WAVE TO SEMI-AUTOMAT-
IC POWER FEED WIRE FEEDER
INTERCONNECTIONS
The Power Wave 455M 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 communication, and
one lead for voltage sensing. The cables are designed to
be connected end to end for ease of extension. The out-
put receptacle on the Power Wave 455M is located
beneath the spring loaded output cover at the bottom of
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.
For convenience sake, the electrode and control cables
can be routed behind the left or right strain reliefs (under
the spring loaded output cover), and along the channels
formed into the base of the Power Wave, out the back of
the channels, and then to the wire feeder.
Due to the flexibility of the platform the configuration may
vary. The following is a general description of the sys-
tem.

SYSTEM DESCRIPTION

The Power Wave 455M 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
