The method used to arrange cables has
a significant affect on welding
properties. As an example, Accupulse
and RMD welding processes can
produce high welding circuit inductance
depending on cable length
arrangement. This can result in limited
current rise during droplet transfer into
the welding puddle.
The electrode 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 Axcess
welding power source 4-pin connector
located above the negative output
terminal. This work sense
automatically compensates 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.
