GENERAL DESCRIPTION

General Physical Description

The LN-25™ PIPE is specially engineered to be the most rugged portable wire feeder available and meets the individual welder needs. This model includes a gas solenoid for flexibility to run most wire processes.

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™ PIPE is the 2 roll MAX- TRAC™ 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™ PIPE has only two p.c. boards that are designed to be simple, reliable and easy to service.

General Functional Description

The LN-25™ PIPE as designed is a simple, robust feeder. Standard features include a calibrated wire feed speed dial, 2 step/trigger interlock switch, Gas Purge and Cold Feed.
