Advantage Lincoln
• Lincoln’s unique fixed inductance design delivers exceptional
short-circuit metal transfer characteristics.
• 115V and 42V wire feeder auxiliary power with circuit breaker
protection.
• Connect wire feeders via either 14-pin MS-type or
terminal strip.
• Internal components, including windings, rectifiers and circuit
boards, are coated to protect against the effects of moisture
and corrosion.
