Advantage Lincoln
• Precision Arc Perfomance
• Quality & Reliability
-
Stack them three-high or purchase an affordable package that
includes the new LF-72 feeder, a Magnum® 400 MIG gun and
more!
-
-
-
Environmentally protected transformer and power rectifier are
rugged and reliable.
Provides line voltage compensation for maintaining weld
consistency, even with changes of 10%.
-
Two output connectors allow you to optimally connect to high or
low inductance for arc conrol. Use low inductance output
connection when short-arc welding, and high inductance output
connection with spray and globular transfer welding
Three-year warranty on parts and labor; seven-year warranty on
power rectifier.
• Features & Innovations
-
Compact unit is 20 lbs. (9.0 kg) lighter and significantly smaller
than competitive models — save your space!
-
-
Easy access Twist-Mate® connection on the front of the machine.
Digital Ammeter/Voltmeter read-out display allows presets for
added convenience and accuracy.
