1. Direction of travel.
2. Connect all sense leads at the end of the weld.
3. Connect all work leads at the beginning of the weld.

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.
Best connection

Both Sense# leads are out of the current paths.

Both Sense# leads detect arc voltage accurately.

No voltage drop between Arc# and Sense# leads.

Best start, best arcs, most reliable results.

Control Cable Connections
General Guidelines
These Guidelines apply to all commumication cables
including optional DeviceNet and Ethernet
connections.

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
®
/MAXsa™ systems. Most are designed to be
connected end to end for ease of operation.

Always use the shortest cable lenghts possible.
DO NOT coil excess cable.
It is recommended that
the total length of Control cable does not exceed
30.5m. The use of non standard cables, especially
in lengths greater than 7,5m, can lead to
communication problems (system shutdowns), poor
motor acceleration (poor arc starting), and low wire
driving force (wire feeding problems).

Best results will be obtained when control
cables are routed separate from the weld cables.
This minimizes the possibility of interference
between the high currents flowing through the weld
cables, and the low level signals in the control
cables.
Common Equipment Connections
Connection Between MAXsa™ Controller and
MAXsa™ series Wire Drive (K1785-xx)
The 14 pin Wire Drive Control Cable (K1785-xx)
connects the Controller (MAXsa™ 10 or MAXsa™ 19) to
the Wire Drive (MAXsa™ 22 or MAXsa™ 29). This cable
should be kept as short as possible.
Connection Between Power Source and the
MAXsa™ Controller (K2683-xx - ArcLink Control
Cable).
Single and tandem arc systems are typically controlled
by a MAXsa™ 10 Controller. In a tandem, or multi-arc
system, each arc requires its own dedicated controller.
The 5-pin ArcLink control cable connects the power
source to the MAXsa™ 10. If there is more than one
power source per arc, it connects from the MAXsa™ 10
to the power source designated as the Master for that
arc. The control cable consists of two power leads, one
twisted pair for digital communication, and one lead for
voltage sensing (67).
NOTE: Connections Between Power Source and
Optional DeviceNet Programmable Logic
Controller(PLC).
It is sometimes more practical and cost effective to use a
custom PLC interface to control a multi-arc sys-tem
(refer to the "DeviceNet Configuration" section for
interface information). The Power Wave AC/DC 1000 is
equipped with a 5-pin DeviceNet mini style recepta-cle
for this purpose. The receptacle is located on the rear
panel of the machine See Figure Case Back
Components. The DeviceNet cable is keyed and
polarized to prevent improper connection.
