General Physical Description

The LN-25™ IRONWORKER is specially engineered to be the most rugged portable wire feeder available and meets the individual welder needs.

The plastic case is molded from a high impact, flame retardant plastic for durability and low weight. The patent pending design keeps the internal components protected and dry.

The heart of the LN-25™ IRONWORKER 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 powers the patent pending drive rolls for smooth, steady feeding without slippage.

The LN-25™ IRONWORKER with a 450 amp, 60% duty cycle rating, is ready for heavy duty welding.

General Functional Description

The LN-25™ IRONWORKER have adjustable WFS range for improving the knob sensitivity. 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 digi- tal 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.

EQUIPMENT LIMITATIONS

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