connected end to end for ease of extension (do not
exceed more than 30,5m total control cable length). The
output receptacle on the Power Wave 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
system. For specific configuration information, consult
the semi-automatic Power Feed instruction manual.
System description
The Power Wave 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 setup.
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.
Welding with multiple Power Waves
WARNING: Special care must be taken when more
than one Power Wave is welding simultaneously on a
single part. Arc blow and arc interference may occur or
be magnified.
Each Power Wave requires a work lead from the work
stud to the welding fixture. Do not combine all of the
work leads into one lead. The welding travel directions
should be in the direction moving away from the work
lead as shown below. Connect all of the work sense
leads from each power source to the work piece at the
end of the weld.
For the best results when pulse welding, set the wire
size and wire feed speed the same for all the Power
Waves. When these parameters are identical, the
pulsing frequency will be the same, helping to stabilize
the arcs.
Every welding gun requires a separate shielding gas
regulator for proper flow rate and shielding gas
coverage.
Do not attempt to supply shielding gas for two or more
guns from only one regulator.
If an anti-spatter system is in use then each gun must
have its own anti-spatter system (see picture below).

2. Connect all Work Sense leads at the end of the
joint.
3. Connect all Welding Sense leads at the beginning of
the joint.

guidelines
Bad connection
•
Current flow from Arc#1 affects Sense#2.
•
Current flow from Arc#2 affects Sense#1.
•
Neither sense lead picks up the correct work
voltage, causing starting and welding arc instability.
Better connection
•
Sense#1 is only affected by weld current from
Arc#1.
• Sense#2 is only affected by weld current from
Arc#2.
•
Due to voltage drops across work piece, Arc voltage
may be low, causing need for deviation from
standard procedures.
