4-1. Features And Benefits

Auto-Linet Power Management Technology is circuitry that automatically adapts the power source to the primary voltage being applied

(see Section 5-7).

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

improves 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

machine.

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 4-7).

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 pulse parameters increase

or decrease matching the power output to the wire speed (see Section 6-2).

4-2. 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).

4-3. Serial Number And Rating Label Location

The serial number and rating information for this product is located on the rear panel. Use rating label to determine input power requirements and/or

rated output. For future reference, write serial number in space provided on back cover of this manual.

4-4. Unit Specifications

Do not use information in unit specifications table to determine electrical service requirements. See Sections 5-6 and 5-7 for information on con-

necting input power.

This equipment will deliver rated output at an ambient air temperature up to 1045F (405C).
