Features And Benefits

Auto-Line Power Management Technology is circuitry that automatically adapts the power source to the primary voltage being applied (see
™
Sections 5-8and 5-9).
LVC Line Voltage Compensation is circuitry that keeps the power source output constant regardless of input power fluctuation.
™
Wind Tunnel Technology circulates air over components that require cooling, not over electronic circuitry, which reduces contaminants and im-
™
proves reliability in harsh welding environments.
Fan-On-Demand 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 4-9).
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-Arc TIG starts provide a contamination free weld without the use of high frequency in the Lift-Arc TIG Welding Mode (see Section 7-3).
™
Synergic Pulsed MIG Operation allows single knob control of the arc. As wirefeed speed is increased or decreased, the pulse parameters in-
crease or decrease matching the power output to the wire speed (see Section 6-3).

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).
Programmable Hot Start allows the start amperage and time to be changed for 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 Sec-
tions 8-2 and 8-8).
SharpArc optimizes the size and shape of the arc cone, bead width and appearance, and puddle fluidity in Pulsed MIG Welding Mode(see Sec-
™
tion 8-4).

Information About Default Weld Parameters And Settings

NOTICE – Each welding application is unique. Although certain Miller Electric products are designed to determine and default to certain typical
welding parameters and settings based upon specific and relatively limited application variables input by the end user, such default settings are
for reference purposes only; and final weld results can be affected by other variables and application-specific circumstances. The appropriate-
ness of all parameters and settings should be evaluated and modified by the end user as necessary based upon application-specific require-
ments. The end user is solely responsible for selection and coordination of appropriate equipment, adoption or adjustment of default weld
parameters and settings, and ultimate quality and durability of all resultant welds. Miller Electric expressly disclaims any and all implied warran-
ties including any implied warranty of fitness for a particular purpose.
