DEFINITION OF WELDING TERMS

WFS

• Wire Feed Speed

CC

•Constant Current

CV

•Constant Voltage

GMAW

• Gas Metal Arc welding

SMAW

•Shielded Metal Arc welding

FCAW

•Flux Core Arc Welding

General Functional Description

The RED-D-ARC LN-25™ PRO EXTREME has adjustable WFS range for improving the knob sensitiv- ity. The low range is great for critical welds with Innershield wires, and the upper range is suitable for general purpose welding. Selection of the WFS range is by a rocker switch or through the set-up menu on meters with digital displays.

RECOMMENDED PROCESSES

•GMAW

•FCAW

PROCESS LIMITATIONS

•GMAW-P procedures must be qualified by the cus- tomer.

•Across-the-Arc models are not recommended for stitch or spot welding.

GENERAL DESCRIPTION

General Physical Description

The RED-D-ARC LN-25™ PRO EXTREME is spe- cially engineered to be the most rugged portable wire feeder available.

This model includes a gas solenoid for the flexibility to run most wire processes.

The plastic case is molded from a high impact, flame retardant plastic for durability and low weight.

The heart of the RED-D-ARC LN-25™ PRO EXTREME is the 2 roll MAXTRAC™ drive. The patented features on the wire drive offer tool-less changing of the drive rolls and wire guides for quick spool changes. A tachometer controlled motor pow- ers the patented drive rolls for smooth, steady feeding without slippage.

With a 450 amp, 60% duty cycle rating, these feeders are ready for heavy duty welding.

EQuIPMENT LIMITATIONS

•The duty cycle of the wire feeder is 450A, 60%. Duty cycle is based upon the amount of welding per- formed in a 10 minute period.

•The maximum spool size is 45 lb. (24 Kg), 12” (305mm) diameter.

•Maximum FCAW gun length is 15 ft.

•Maximum GMAW gun length is 25 ft.

•K2330-1 Timer Kits do not work with the feeder. Use K2330-2 kits.

•Push-pull guns do not work with the RED-D-ARC LN-25™ PRO EXTREME .

•The digital displays do not show preset voltage

•Not compatible with K489-7 Euro connector (except K2614-7,-8)
