The arrangement of the cables has an
effect that is significant to the welding
properties. As an example, Accupulse
welding process can produce high
welding circuit inductance depending
on cable length and arrangement. This
can result in limited current rise during
droplet transfer into the welding puddle.
The sense lead is contained in the
feeder control cable and automatically
becomes enabled for all
semi-automatic processes. The work
sense lead connects to the welding
power source 4-pin connector located
above the positive output terminal. This
work sense lead automatically compen-
sates for work cable voltage drop when
connected to the welding power source.
Do not coil excess cables. Use cables
that are the appropriate length for the
application. Whenever using long weld
cables [longer than 50 ft (15 m)] try to
arrange positive and negative weld
cables together to reduce the magnetic
field surrounding the cables. Avoid
coupling the feeder and work sense
leads with the weld cables.
