Welding with Multiple Arcs
Special care must be taken when more than one arc is
welding simultaneously on a single part. Arc blow and
arc interference may occur or be magnified. Each power
source requires a work lead from the work stud to the
welding fixture. Do not combine all of the work leads into
one lead. Perform welding in the direction away from the
work leads. Connect all of the work sense leads from
each power source to the work piece at the end of the
weld, such that they are out of the path of the weld
current.
For the best results when pulse welding, set the wire
size and wire feed speed the same for all the arcs. When
these parameters are identical, the pulsing frequency will
be the same, helping to stabilize the arcs.

Control Cable
ArcLink Control Cables are available in two forms:
K1543-xx series for most indoor or factory
installations.
K2683-xx series for outdoor use or when the
equipment is frequently moved.
ArcLink/LincNet control cables are special high quality
cables for digital communication. The cables are copper
5 conductor cable in a SO-type rubber jacket. There is
one 20 gauge twisted pair for network communications.
This pair has an impedance of approx-izmately 120
ohms and a propagation delay per foot of less than 2.1
nanoseconds. There are two 12 gauge conductors that
are used to supply 40VDC to the network. The fifth wire
is 18 gauge and is used as an electrode sense lead.
Use of non-standard cables may lead to system
shutdowns, poor arc starting and wire feeding problems.
Control cables may be connected end to end to extend
their length. Use a maximum of 60m of control cable
between components.
