SECTION 4 − SPECIFICATIONS
4-1. Features And Benefits
LVC Line Voltage Compensation is circuitry that keeps the power source output constant regardless of input pow-
er fluctuation.
Wind Tunnel Technology circulates air over components that require cooling, not over electronic circuitry, which
reduces contaminants and improves reliability in harsh welding environments.
Fan-On-Demand 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 4-7).
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).
ArcReach
)
Remote Control allows remote control of various functions of the power source by an ArcReach
compatible wire feeder or remote control device, without the use of a control cable (see Section 6-3). Operation of
the ArcReach feature is dependent on the Mode Switch Setting (See section pertaining to process being used).
Auto−Line Circuitry automatically adapts to primary voltage (208 to 575 VAC) without having to relink the power
source.
Low OCV Operation This unit is factory configured to provide low Open Circuit Voltage (OCV) (see Section 9-4).
Cable Length Compensation will compensate for voltage drop in the weld cables by automatically adjusting the
voltage at the power source while using a compatible wire feeder. The operator only needs to preset the desired weld
voltage at the feeder without manually compensating for weld cable length.
4-2. Arc Controls
Arc Control in Stick Mode allows the arc characteristics, soft versus stiff, to be changed for specific applications
and electrodes in Stick Welding Mode (see Section 9-3).
Arc Control in Wire Mode influences the arc stiffness, bead width and appearance, and puddle fluidity in MIG and
V-Sense Feeder Welding Modes (see Sections 8-2 and 8-4).
Programmable Hot Start Time allows the start amperage time to be changed for Stick Welding Modes. This helps
eliminate electrode sticking during arc initiation. (see Section 9-3).
