Lincoln LN-25 Wire Feeder

[platypus20]

I needed a wire feeder for a job in Hawaii, about 4 yrs ago, and was unaware of the brand or type of welder that was to be provided by the contractor, after much research, I went with a Lincoln LN-25 semiautomatic wire feeder. The LN-25 can be used with either a constant current or constant voltage DC power source, basicly any non square wave DC welder. It has a contactor, so the tip is dead when, the trigger is released, and has a built in shielding gas solenoid. This is a popular wire feeder for use with gas drive welders, and can be connected directly into the welding lead, or with the use of optional cables wired directly into the control circuit of the welder.

300 amps @ 60% duty cycle
50-700 ipm, adjustable wire speeds
solid wire sizes .023-.068" / fluxcore .045-5/64" / aluminum .035-1/16"
Preflow timer .1-1 sec / postflow timer .1-5 sec
28 lbs weight, designed to fit down a utility manhole
8", 11-12# or 12", 44-45" wire spools

I've used this wire feeder many times, and have had great results, with both Lincoln and Miller gas drives. My main power source is a Lincoln V-350pro, but have also used with great success a Miller XMT-304, and have in an emergency powered it with a Lincoln AC/DC buzzbox.

I had a friend come across one "cheap enough" and asked me about running it on his Dial Arc (was mine)....at first I told him I'm not sure, but doubt it....I was @ my LWS later and asked one of the "oler guys" there and he said sure can...... he hasn't hooked it up yet what does he need to do so?...
Thanks,
Mike

Mike,

Run the positive lead from the welder into the feeder, run the negative lead from the welder to the work, run the voltage sensing wire from the feeder to the work. Hook up the gas, set the CV/CC switch to CC, turn the power on, make a rough adjustment to the welder amps, the adjust the wire speed to get the best weld puddle. If you going to run fluxcore, run the positive lead to ground, the negative to the feeder, and make your adjustments, then weld . Does he have a manual, it can be downloaded fron Lincoln.

I couldn't ever get mine to work right with the old lincoln AC/DC, I tried every combination I could think of.

Can the LN-25 be ran with flux core wire out in the field? Thanks.

NM,

Yes, I run fluxcore with it all the time, all it takes is switching the welding leads polarity, compared to regular mig welding.

I have a 25 that I run off of my GXT, I use Hobart fabsheild gas-less flux core and it works fine out in the feild. Tim

I run dualshield and fluxcore off my LN-25, and have never had a bit if trouble with it. I got it used off Ebay a few years ago.
