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 Section 5-5).
LVCt Line Voltage Compensation is circuitry that keeps the power source output constant regardless of input pow-
er 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 con-
taminants 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 4-4).
Auto Remote Sense enables the unit to automatically sense the connection of a remote control. Operation of the
remote control is dependent on the Mode Switch Setting (see Section 6-2).
Lift-Arct TIG starts provide a contamination free weld without the use of high frequency in the Lift-Arc TIG Welding
Mode (see Section 7-3).
Adaptive Hot Startt for Stick increases the output amperage at the start of a weld, eliminating electrode sticking
in CC and Stick Welding Modes (see Sections 9-2 and 9-3).
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 6-3).
4-3. Arc Controls
DIG control allows the arc characteristics, soft versus stiff, to be changed for specific applications and electrodes in
CC and Stick Welding Modes (see Sections 9-2 and 9-3).
Inductance influences the arc stiffness, bead width and appearance, and puddle fluidity in MIG and V-Sense Feeder
Welding Modes (see Sections 8-2 and 8-7).
SharpArct optimizes the size and shape of the arc cone, bead width and appearance, and puddle fluidity in Pulsed
MIG Welding Mode (see Section 8-4).
