Wire Drive Pressure Setting
(See Figure #10)
Most wires operate well with a pressure setting of “2”.
The best drive roll pressure varies with wire type, wire
surface, lubrication and hardness. Too much pressure
may crush the wire or cause "birdnesting", but too little
pressure could cause slippage.
Set the drive roll pressure by:
1. Press the end of the gun against a solid object that
is electrically isolated from the welder output and
press the gun trigger for several seconds.
2. If the wire "birdnests" or jams, the drive roll pressure
is too high. Reduce the pressure by one turn of the
knob, run new wire through the gun, and repeat step
1.
3. If the only result is slippage, disconnect the gun and
pull the gun cable forward about 6" (150mm). There
should be a slight waviness in the exposed wire. If
there is no waviness, increase the pressure setting
one turn, reconnect the gun and repeat the above
step electrode lead to the gun adapter.

Weld Cables, Coaxial
(See figure #30)
Coaxial welding cables are specially designed welding
cables for STT™ and pulse welding. Coaxial weld cables
feature low inductance, allowing fast changes in the weld
current. Regular cables have a higher inductance which
may distort the STT™ waveshape. Inductance becomes
more severe as the weld cables become longer.
Coaxial cables work best for high performance
waveforms and when:
long cables are present
the cables are housed in a metal tray
A coaxial weld cable is constructed with multiple small
leads wrapped around one large lead. The large inner
lead connects to the electrode stud on the power source
and the electrode connection on the wire feeder. The
small leads combine together to form the work lead, one
end attached to the power source and the other end to
the work piece.

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.
A. Direction of travel
B. Connect all sense leads at the
end of the weld
C. Connect all work leads at the
beginning of the weld

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.
