Lincoln Electric IM887 K2490-1 MAGNUM 250 LX SPOOL GUN - Manual (Page 8)

PRODUCT DESCRIPTION
The 250 LX spool gun is a lightweight, handheld combined semiau-
tomatic wire feeder and welding gun, designed primarily for alu-
minum welding using argon shielding gas. The feeding distance of
the self-contained wire supply to the arc is only several inches, elim-
inating the wire feeding problems normally associated with feeding
soft aluminum electrode through a conventional gun and cable
assembly. The cable included with the spool gun allows welding up
to 25 feet (7.6 m) from the power source.
The gun is intended for use with Power Mig 255C AND Power Mig
350MP Power Sources. For other applications, contact your local
Lincoln Electric sales office or distributor.
The spool gun is ideal for aluminum fabrication in industrial shops,
automobile body shops, marinas and for the advanced hobbyist.

RECOMMENDED PROCESSES AND
EQUIPMENT
The spool gun can be used to weld aluminum and aluminum alloys
using Gas Metal Arc Welding or GMAW (also known as MIG)
process, which requires a supply of shielding gas. Argon is normal-
ly used due to its smooth, stable arc, good metal transfer, and low
cost. Positive polarity gives good penetration and affords a base
metal cathode cleaning effect.
