4-2. Features And Benefits

Auto-Linet Power Management Technology is circuitry that automatically adapts the power source to the primary voltage being applied (see Sec-
tions 5-8 and 5-9).
LVCt Line Voltage Compensation is circuitry that keeps the power source output constant regardless of input power fluctuation.
Wind Tunnel Technologyt circulates air over components that require cooling, not over electronic circuitry, which reduces contaminants and im-
proves reliability in harsh welding environments.
Fan-On-Demandt cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through the ma-
chine.
Thermal Overload Protection automatically shuts down the unit, only when necessary to prevent damage to internal components if the duty cycle
is exceeded or air flow and cooling are restricted (see Section 4-4).
Auto Remote Sense enables the unit to automatically sense the connection of a remote control.
Synergic Pulsed MIG Operation allows single knob control of the arc. As wirefeed speed is increased or decreased, the pulsed parameters increase
or decrease matching the power output to the wire speed (see Section 6-2).

4-3. Arc Controls

Inductance influences the arc stiffness, bead width and appearance, and puddle fluidity in MIG Welding Mode
(see Section 7-2).
SharpArct optimizes the size and shape of the arc cone, bead width and appearance, and puddle fluidity in Pulsed MIG Welding Mode (see Section
7-4).
