of the machine.
General Description
The Power Wave®Advanced Module is an accessory
enabling compatible power sources to perform the DC+,
DC-, AC, STT or any combination of these functions. It
is intended for use with medium range “S” – series
Power Wave power sources such as the S350 or S500.
The Advanced Module will limit the output of an S500
(CE) or R500 to a maximum of 350 amps, regardless of
process. The module itself is a low profile pedestal,
designed to seamlessly integrate with compatible power
sources and water coolers.
Location, Environment and Mounting
(see Figure #1&#2)
Mount the Advanced Module directly to the bottom of a
compatible Power Wave®“S” series power source
utilizing the quick lock mechanism as shown. The
Advanced Module will operate in harsh environments
and can be used outdoors. Even so, it is important that
simple preventative measures are followed in order to
assure long life and reliable operation.
The machine must be located where there is free
circulation of clean air such that movement into and
out of the louvers will not be restricted.
Dirt and dust that can be drawn into the machine
should be kept to a minimum. The use of air filters
on the air intake is not recommended because
normal air flow may be restricted. Failure to
observe these precautions can result in excessive
operating temperatures and nuisance shutdown.
Keep the machine dry. Shelter from rain and snow.
Do not place on wet ground or in puddles.
Do not mount the Power Wave®“S” series power
source and Advanced Module combination over
combustible surfaces. Where there is a combustible
surface directly under stationary or fixed electrical
equipment, that surface shall be covered with a
steel plate at least 1.6mm thick, which shall extend
not less than 150mm beyond the equipment on all
sides.

Machine Grounding and High
Frequency Interference Protection
The host power source must be earth grounded! See
your local and national electrical codes for proper
grounding methods.
The Advanced Module utilizes a high frequency impulse
to initiate the arc of selected GTAW (TIG) welding
procedures. Although the power of this impulse is
significantly less than traditional arc stabilization circuits,
it is best to locate the power source and Advanced
Module away from radio controlled machinery as it may
adversely affect the operation of the RF controlled
equipment, which may result in bodily injury or damage
to the equipment.
The high frequency starting impulse may also cause
radio, TV and electronic equipment interference
problems. These problems may be the result of radiated
interference. Proper grounding methods can reduce or
eliminate radiated inter- ference.
Radiated interference can develop in the following four
ways:
1. Direct interference radiated from the welder.
2. Direct interference radiated from the welding leads.
3. Direct interference radiated from feedback into the
power lines.
4. Interference from re-radiation of “pickup” by
ungrounded metallic objects.
Keeping these contributing factors in mind, installing
equipment per the following instructions should minimize
problems.
1. Keep the welder power supply lines as short as
possible and enclose as much of them as possible
in rigid metallic conduit or equivalent shielding for a
distance of 50 feet (15.2m). There should be good
electrical contact between this conduit and the
welder case ground. Both ends of the conduit
should be connected to a driven ground and the
entire length should be continuous.
2. Keep the work and electrode leads as short as
possible and as close together as possible. Lengths
should not exceed 7.6m. Tape the leads together
when practical.
3. Be sure the torch and work cable rubber coverings
are free of cuts and cracks that allow high frequency
leakage.
4. Keep the torch in good repair and all connections
tight to reduce high frequency leakage.
5. The work piece must be connected to an earth
ground close to the work clamp, using one of the
following methods:
A metal underground water pipe in direct
contact with the earth for ten feet or more.
A 19mm galvanized pipe or a 16mm solid gal-
vanized iron, steel or copper rod driven at least
eight feet into the ground.
The ground should be securely made and the grounding
cable should be as short as possible using cable of the
same size as the work cable, or larger. Grounding to the
building frame elec trical conduit or along pipe system
can result in re-radiation, effectively making these
members radiating antennas.
6. Keep cover and all screws securely in place.
7. Electrical conductors within 15.2m of the welder
should be enclosed in grounded rigid metallic
conduit or equivalent shielding, wherever possible.
Flexible metallic conduit is generally not suitable.
8. When the welder is enclosed in a metal building, the
metal building should be connected to several good
earth driven electrical grounds around the periphery
of the building.
Failure to observe these recommended installation
procedures can cause radio or TV and electronic
equipment interference problems and result in
unsatisfactory welding performance resulting from lost
high frequency power.
Stacking
Stacking of the Power Wave®Advanced Module shall
not exceed a power source above and one module
below.
Duty Cycle
The Advanced Module is rated at 300 amps at a 100%
duty cycle. It is further rated to support 350 amps at 40%
duty cycle. The duty cycle is based on 10 minute period.
A 40% duty cycle represents 4 minutes of welding and 6
minutes of idling in a ten-minute period.
Note: the Advanced Module is capable of withstanding a
peak output current of 600 amps. The allowable
maximum average output current is time dependant, and
ultimately limited by the host power source.
Example: 40% Duty Cycle:
Welding for 4 minutes. Break for 6 minutes.

Control Cable Connections
General guidelines
Genuine Lincoln control cables should be used at all
times (except where noted otherwise). Lincoln cables
are specifically designed for the communication and
power needs of the Power Wave®systems. Most are
designed to be connected end to end for ease of
extension. Generally, it is recommended that the total
length not exceed 30.5 m. The use of non-standard
cables, especially in lengths greater than 25 feet, can
lead to communication problems (system shutdowns),
poor motor acceleration (poor arc starting), and low wire
driving force (wire feeding problems). Always use the
shortest length of control cable possible, and DO NOT
coil excess cable.
WARNING
Regarding cable placement, best results will be obtained
when control cables are routed separate from the weld
cables. This minimizes the possibility of interference

English English
6
between the high currents flowing through the weld
cables, and the low level signals in the control cables.
These recommendations apply to all communication
cables including ArcLink® connections.
Special Considerations for High
Frequency GTAW (TIG) Welding
Although the equipment has been designed to withstand
the high frequency starting impulse, special care should
be taken to isolate this energy from the control signals of
the welding system and other equipment. The following
guidelines apply:
Follow the recommendations in the Machine
Grounding and High Frequency Interference
Protection section of this document.
Locate the control cables and adjacent equipment
away from the weld cables and TIG torch.
Consider optical isolation for critical applications via
the Ethernet interface on the power source (such as
ArcLink XT, Production Monitoring, etc.). Ethernet to
fiber media con- verters are commercially available,
and will significantly improve the electrical and
magnetic interference immunity of these signals.
Connection between Power Source and
Advanced Module (Arclink®, Voltage
Sense and Differential I/O Pigtails)
The pigtail connections on the Advanced Module include
all signal and power lines required for proper operation.
With the Advanced Module securely fastened to the
power source, connect the pigtails to their respective
receptacles on the back and front of the power source
per the connection diagrams located in this document.
Arclink Pigtail (5 pin)
Provides power to the Advanced Module as well as a
digital link for system information.
Voltage Sense Pigtail (4 pin)
Provides accurate voltage feedback to the power source
from either the output studs of the module or remote
sense lead locations based on the process.
Differential I/O Pigtail (6 pin)
Provides high speed control signals for polarity and STT
function.
Special Instructions
CE machines:
A special ArcLink®and Differential I/O receptacle kit is
provided with the Advanced Module CE Kit (K3980-1) for
installation into the host power source. Follow the
instructions provided with the kit. (reference instruction
sheet M22499)
Power Wave S350 (Code 11589)
Some earlier vintage S350 power sources may not
include a 6 pin Differential I/O receptacle. If the
receptacle is not present on the host power source,
contact the Lincoln Electric Service Department to obtain
an S350/STT Retrofit Kit (S28481).
Connection between Power Source and
Advanced Module to Arclink®wire
feeders (K1543 or K2683 Arclink®
Control Cable)
The K2912-1 Advanced Module includes an ArcLink®
output receptacle for connection to compatible wire
feeders. The 5 pin ArcLink®receptacle is located on the
lower rear portion of the Advanced Module. The control
cable is keyed and polarized to prevent improper
connection.
Best results will be obtained when control cables are
routed separate from the weld cables, especially in long
distance applications. The recommended combined
length of the ArkLink®control cable network should not
exceed 200ft.
CE machines:
S350 and S500 CE Power Source have an ArcLink
output receptable located on the case front. The ArcLink
wire feeder can be attached to either the receptable on
the power source case front or Advanced Module case
back.

Electrode and Work Connections
Connect the positive and negative input connections and
electrode and work output cables per the connection
diagrams included in this document. Size and route the
cables per Table 1.
Wire feeders should always be connected to the
GMAW elec- trode stud.
TIG (GTAW) torches and Stick (SMAW) holders
should always be connected to the GTAW/SMAW
electrode.
The workpiece should always be connected to the
work stud.
The output polarity is automatically configured
based on the selected weld mode. There is no need
to reverse the output cables.
WARNING
Never reverse the polarity at the input of the Advanced
Module (DO NOT connect the negative stud of the
power source to the positive input of the Advanced
Module). Although this will not damage the Advanced
Module, it will prevent welding output.

General Guidelines
Select the appropriate size cables per the “Output Cable
Guidelines” (See Table 1). Excessive voltage drops
caused by undersized welding cables and poor
connections often result in unsatisfactory welding
performance. Always use the largest welding cables
(electrode and work) that are practical, and be sure all
connections are clean and tight.
Note: Excessive heat in the weld circuit indicates
undersized cables and/or bad connections.
Route all cables directly to the work and wire feeder,
avoid excessive lengths and do not coil excess
cable. Route the electrode and work cables in close
proximity to one another to minimize the loop area
and therefore the inductance of the weld circuit.
Always weld in a direction away from the work
(ground) connection.
See Table 1 for copper cable sizes recommended for
different currents and duty cycles. Lengths stipulated are
the distance from the welder to work and back to the
welder again. Cable sizes are increased for greater
lengths primarily for the purpose of minimizing cable
drop.
Cable Inductance and its Effects on
Welding
Excessive cable inductance will cause the welding
performance to degrade. There are several factors that
contribute to the overall inductance of the cabling system
including cable size, and loop area. The loop area is
defined by the separation distance between the
electrode and work cables, and the overall welding loop
length. The welding loop length is defined as the total of
length of the electrode cable (A) + work cable (B) + work
path (C) (see Figure #4 below). To minimize inductance
always use the appropriate size cables, and whenever
possible, run the electrode and work cables in close
proximity to one another to minimize the loop area.
Since the most significant factor in cable inductance is
the welding loop length, avoid excessive lengths and do
not coil excess cable. For long work piece lengths, a
sliding ground should be considered to keep the total
welding loop length as short as possible.
Figure #4
Remote Sense Lead Connections
Voltage Sensing Overview
Certain welding process requires the use of remote
voltage sense leads to more accurately monitor the
conditions of the arc. These leads originate in the power
source, and are connected and configured through the
Advanced Module. Consult the connection diagrams
included in this manual for detailed information.
Note:
Not all processes run through the Advanced Module do
not necessarily require sense leads, but will benefit from
their use. Consult the power source instruction manual
for recommendations.
WARNING
DO NOT connect the remote electrode sense (67) lead
to the TIG (GTAW) output.
General Voltage Sensing Considerations for Multiple
Arc Systems
Special care must be taken when more than one arc is
welding simultaneously on a single part. The placement
and configuration of remote work voltage sense leads is
critical to the proper operation of multiple arc AC and
STT®applications.
Recommendations:
Position the sense leads out of the path of the
weld current. Especially any current paths
common to adjacent arcs. Current from adjacent
arcs can induce voltage into each others current
paths that can be misinterpreted by the power
sources, and result in arc interference.
For longitudinal applications, connect all work
leads at one end of the weldment, and all of the
work voltage sense leads at the opposite end of the
weldment. Perform welding in the direction away
from the work leads and toward the sense leads.
(See Figure #5).

For circumferential applications, connect all work leads on one side of the weld joint, and all of the work voltage sense
leads on the opposite side, such that they are out of the current path.
Bad connection
Current flow from Arc#1 affects Sense lead #2.
Current flow from Arc#2 affects Sense lead #1.
Neither sense lead picks up the correct work voltage, causing starting and welding arc instability.
Better connection
Sense lead #1 is only affected by current flow from Arc#1.
Sense lead #2 is only affected by current flow from Arc#2.
Due to voltage drops across workpiece, Arc voltage may be low, causing need for deviation from standard
procedures.
