MIG Flux-Cored

LN-25 Wire Feeder

Portable, Construction Wire Feeder

The LN-25 semiautomatic wire feeder is ideal for field or construction use. Since it is

powered across the arc, no control cables are needed! Simply connect the weld cable,

attach the arc sensing clip, and you re ready to go. This portable MIG and flux-cored wire

feeder comes in a fully enclosed case to protect against damage on the job site. The

LN-25 features a tool-less quick release mechanism for easy wire changing, and it

accepts 10-44 lbs. (4.5-19.9 kg) wire packages for plenty of welding versatility.

PERFORMANCE

• 2-roll wire drive system for easy wire feeding.

• The LN-25 provides constant wire feed speed for use with

constant voltage (CV) power sources, and arc sensing wire

feed speed for use with constant current (CC) power sources(1).

• Dynamic braking system stops wire feed motor quickly to

minimize crater sticking problems.

(1) Most semiautomatic wire welding processes perform better using CV power sources.

Be sure the proper power source is used for your application. Contactor life may be

shortened in applications using CC power sources with high OCV.

QUALITY AND RELIABILITY

• Fully enclosed molded case meets UL94-VO flammability

resistance and is heat, spatter, and impact resistant.

• Automatic overvoltage and motor overload shutdown protection.

• Three-year warranty on parts and labor.

• Manufactured under a quality system certified to ISO 9001

requirements.

• CSA approved.

FEATURES

• Tool-less quick release wire drive tension system and gun cable

connections for easy wire or gun changes.

• Optional gas solenoid, timer kit for preflow and postflow of gas,

internal contactor, and remote voltage control kits are available.

• Standard Voltmeter
