CV-400
The rugged CV-400 is ready to tackle MIG and cored wire fabrication and production
work in a variety of industries: transportation, heavy equipment, structural steel,
railroad, furniture, appliances and sheet metal fabrication.
Rugged, Proven Construction for Wire Welding
• Lincoln’s unique fixed inductance design delivers
exceptional short-circuit metal transfer characteristics.
• Connect wire feeders via either 14-pin MS-type or
terminal strip.
• 115V and 42V wire feeder auxiliary power with circuit
breaker protection.
• Internal components, including windings, rectifiers
and circuit boards, are coated to protect against
the effects of moisture and corrosion.
• Electronic and thermostatic protection from current
overload and excessive temperatures. Indicator
light lets you know when machine is reset.
• Three-year warranty on parts and labor.
• Seven-year warranty on power rectifier.

• Two output connectors allow you to optimally connect
to high or low inductance for arc control. Use low
inductance output connection when short-arc welding,
and high inductance output connection with spray and
globular transfer welding.
• Compact unit is 20 lbs. (9.0 kg) lighter and significantly
smaller than competitive models—save your space!
• Easy access Twist-Mate
