Lincoln Electric COUGAR K2704-3 - Manual (Page 8)

PRODUCT DESCRIPTION
The Cougar™ push-pull gun is a lightweight, handheld combined
semiautomatic wire feeder and welding gun, designed primarily for
aluminum welding using argon shielding gas. The cable included
with the push-pull gun allows welding up to 25 (7.62m) or 50 feet
(15.2m) from the power source.
The gun is intended for use with Power Wave C300, Power Feed
10M, Power Feed 25M and Power Mig 350MP Power Sources. For
other applications, contact your local Lincoln Electric sales office or
distributor.
The push-pull gun is ideal for aluminum fabrication in industrial
shops, automobile body shops, marinas and for the advanced hob-
byist.
RECOMMENDED PROCESSES AND
EQUIPMENT
The push-pull 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.
