Longevity Migweld 140 AWESOME MACHINE!!!

Shield Arc · Jan 21, 2015

A lot of Lincoln engine drives are rated at 60% duty cycle. I think they're severely under rated my self.

Used it more this afternoon .. It's a sweet user friendly Mig ... I build 5 chambers for the accumulator .. Played with volts and wire speed it's just so easy to get a good sizzle!!

Here's a picture of one.

The only thinkg that scares me about these units is the wire feed mechanism -- very flimsy, and lots of complaints online. When I saw the mechanism on a Hobart, it was no comparison (which is about right, as the Hobart is $150 more).

I'm not sure when they made the change to the feed mechanism ... I did see pictures online of the old style cheap wing nut and found a review where a guy had an issue ..I'll take some photos today of the drive on the unit and get them posted.

Other than the picture of the Lincoln was closer, I don't see much difference.

I've never seen a Longevity Mig welder. But I would think it's about the same as Everlast. When I got to play with roadhunter's Everlast Mig welder I was having a hard time getting the nozzle where I wanted it. I had the gun in my right hand, and trying to remove the nozzle with my left hand. Dumb ol me, I pulled the trigger. Drove the wire right through my welding glove into left hand!:shocked: I've never had that happen before!:laughing:
I'm really disappointed in the drive system in my Lincoln LF-72 wire feeder!:thumbdown: I bought it used, but it will not push 1/16" flux core wire! It will push .045" wire, but nothing bigger

. I have to switch to my LN-25 to run bigger wire.

Thats funny ... not the wire in the hand ... The fact you've never seen a Longevity Mig ...I've never seen other than pictures any of the Everlast units ... wish someone close to me had some I'd love to do a side by side comparison.

Shield, I know I've been welding at least a week less than you (2)

but aren't you 'sposed to use a block of WOOD to test the drive roll pressure??!? :laughing:

Seriously tho, sorry 'bout your "owiee" - I'd have thought your marvelous "red queen" of a neighbor would've given you enough pain without you goin' lookin' fer it

(done there, been that

)...Steve

That's a big improvement over the older design -- if they had that sooner, I'd probably have a Longevity 140 instead of a Hobart 140! I will try to get a pic of Hobart's wire feed system when I get a chance.
