PRODUCT DESCRIPTION
The Magnum Pro 250 LX and Magnum Pro 250 LX GT spool guns
are lightweight, handheld combined semiautomatic wire feeder
and welding guns, designed primarily for aluminum welding using
argon shielding gas. The feeding distance of the self-contained
wire supply to the arc is only several inches, reducing 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 spool gun is ideal for aluminum fabrication in industrial shops,
automobile body shops, marinas and for the advanced hobbyist.
The Magnum PRO 250 LX GT was designed with an internal
solenoid in it. With this gun you can have reliable gas flow while
welding even when your machine doesn't have a solenoid in it. It
has all the features of the Magnum PRO 250 LX and has been
upgraded to withstand the harsh conditions of being used in
rugged environments.
NOTE: Please turn off gas when
not in use.

Instruction Manual
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
normally 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.
