The arrangement of the cables has an
effect that is significant to the 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 Vsense option can be turned On or
Off in the Setup menu or by using the
web pages. The electrode sense lead is
contained in the feeder control cable
and compensates for voltage drop in all
semi-automatic processes when the
Vsense option is On . The work sense
lead connects to the Axcess welding
power source 4-pin connector located
above the negative output terminal. This
work sense lead compensates for work
cable voltage drop when connected to
the welding power source when the
Vsense option is On.
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.
