The Prince XL Spool-gun may be hooked up to the ESAB 251cv Power Supply using the welders built-
in speed control module. This is accomplished by using a MK adapter pigtail (P/N 003-1341) which will
plug directly into the ESAB power supply's 8-Pin amphenol on the front of the machine.
The lug on the Prince XL's power cable will have to be cut off and replaced by a male Dinse connector
(MK P/N: 153-0755). There's a switch on the front upper panel that has to be in the Spool-gun position.
If the Multimaster 260 has ESAB's optional spool gun module already installed, then the 003-1341 MK
adapter pigtail will work.
A Cobramatic system may be connected to this power supply. Use the instructions found in section E-2
for the Cobramatic system. However, the switch on the upper panel of the welder will have to be in the
Spool-gun position.
do not attempt to hook up the Cobramatic system using the 19-Pin amphenol on this unit.
