Lincoln Electric IDEALARC CV-305 User manual

IG Flux-Cored
CV-305
When it comes to welding mild steel, stainless steel, aluminum and alloy
materials, you won’t find a more reliable power source than the CV-305.
This well-engineered CV unit features two inductance connections. Lincoln’s
Twist- ate®output connectors make it easy to choose the right inductance
for your application.
This unit is the most compact unit in its class, yet it’s loaded with
convenient features! Digital meters that can be preset, line voltage
compensation, a remote and local control option, and a 7-year rectifier
warranty — what more do you need?

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