Complete 25' cable with 14P

Note: If unit does not have a 14-Pin see section L-4 .
The PA-L1 Control (P/N 005-0676) comes equipped with a 14 Pin (X-clocked) amphenol connector and
simply plugs into any Lincoln CV-type welder that has a 14 Pin (X) socket. This unit operates on 42
volts and is for "CV" only. If the welder has a remote voltage control, it should be set on "Panel". The
contactor switch should be on "Remote". Most of the newer Lincoln shop machines now use a dinse
style connector (MK P/N 153-0755) which would have to replace the lug on the power cable of the
Prince XL spool gun.
