some larger power sources do not have built in systems for feeding wire, so a dedicated wire feeder is needed, and typically mounted on top of the welding power source.

yes most wire feeders are ready for use with gas.

lincolns site states that the ln-25 doesnt come with the gas solenoid, but its made for MIG and fluxcore so add a solenoid and it should be ready.

Hello all....

What is the difference between a "wire feeder," like a LN-25 and a MIG welder?

Can you use gas (MIG) with a wire feeder?

Thanks guys...

The LN-25 is a "suitcase" wire feeder. It has to be attatched to a power supply in order to work. They have an inlet on the back of the case for gas hook up.
MIG welders are a power supply, with either an internal or external wire feeder. I've seen people trying to sell LN-25's as welders :nono:
Hope this helps!------------ john :drinkup:
