POSaStaRt COnnECtiOnS
The Cobramatic and Cobra II Wire Feeders each have, a single black 14 ga. wire with an
alligator clip, extending from the back connected to the main board. This is the voltage sens-
ing lead for the PosaStart circuit. In order for PosaStart to properly work, this lead must be
connected to the welding GROUND.
Typically, most power supplies will accept
the PosaStart lead connected to either the
work GROUND lug on their front panel or the
GROUND clamp.
However, some newer types of inverters must
have this PosaStart lead connected directly to
the GROUND lug.
Newer Cobramatic units have a CC/CV config-
uration switch on the main board. Consult the
owners manual in order to properly configure
this switch.
