Power MIG® 215XT
MAGNUM 250LX PUSH-PULL GUN
AND PUSH PULL ADAPTER
For heavier duty aluminum applications when use of large
16 pound aluminum spools of wire are desired the follow-
ing push pull gun and adapter kit are available.
Magnum 250LX Push Pull Gun (K2704-1)
This pistol grip push pull gun is similar to the Magnum
250LX spool gun except it is designed to feed large
spools of wire. The Magnum 250LX push pull features a
25 foot power, gas and control cable. It operates as an
assist slave motor pulling the aluminum wire as the Power
MIG® drive motor acts as the master push motor.
Magnum 250LX Push Pull Adapter (K2705-1)
This adapter box is designed to drive the Magnum 250LX
push pull gun when used on a non push ready Lincoln
power source feeder such as the Power MIG® 215XT or
255XT. This box features a 115V cord and plug to power
the box, a control cable with receptacle to connect the
push pull gun’s control cable to, and a 4-pin connector to
connect to the Power MIG® gun trigger receptacle.
Note the Magnum 250LX push pull gun has a wire feed
speed adjustment potentiometer. However this poten-
tiometer only functions on push-pull ready machines like
the Power MIG® 350MP. When the Magnum 250LX is
used on a non-push-pull machine with the K2705-1
adapter, the wire feed speed is set on the control panel of
the machine.
