I just want to share my experience with this particular machine so that others don't go down the same road as I did before doing the proper research.
I have a background that included a lot of welding. I was fortunate enough to always use good quality, high powered machines, though I never owned one. I finally convinced my wife that I had enough welding projects to justify actually owning one of my own. I KNEW what I wanted, but the red, blue and orange brands were out of my price range by over $200. So I came across this Longevity brand and started reading reviews, on HD, Amazon, Wal-Mart, and watched a nice 4 part YouTube review from someone not affiliated with the brand. Although there were some negative reviews, I felt like maybe it was just bad luck for that particular person, and I decided to go for it anyway.
Here's where I got let down... we had to special order it and when it finally came, I was overjoyed and couldn't wait to fire it up and see what it could do. I was however, concerned about the excessive amount of packing tape sealing the box shut. Anyway, I took it home and plugged it in to a dedicated 20 amp circuit I had put in during construction in hopes of having a welder someday. I loaded up a spool and fed it in and squeezed the trigger. The motor turned for about 2 seconds and quit. 2 more seconds and quit. The third time it tried, it popped the breaker. I made sure the tensioner wasn't too tight and the drive wheel was set to the right wire diameter. All Ok. Reset the breaker, and it did the same thing. I didn't even try again. Normally I would have taken that thing apart to see if I could fix it myself... But why? I payed for a brand new machine. Instead, I took it straight off the bench right back into the box... But as I did, I noticed something fishy... On the back of the machine where the fan shroud was there was a glob of black touch up paint (see Pic). I realized it was cosmetic and had nothing to do with the problem I had, but it got me thinking about all that packing tape again! I believe I got a refurbished unit that had been returned before, and I payed for a BRAND NEW machine. Well I started to get angry and thought about going straight to the manufacturer with a complaint. But, I packed it up and returned it today, but left a note for the next person in the box just for fun.
Here's where I went wrong, but also what I did right:
I was right to buy it through Home depot because of the hassle free return. Its gone, I'm done...
I was wrong because at no point did I research any WELDING forums... seriously... stop now and go to a welding forum like weldingweb.com and type in Longevity in the search bar. There are mostly bad reviews/posts, but there are also good reviews/posts from people hiding behind the company. If you read them it wont take you long to figure out who they are. People LOSE their minds over this brand, from poor customer service (if any at all), DOA machines like mine, and having to return the whole unit to Hayward, CA for any repairs. (on YOUR dime if its out of its warranty period)
I was very disappointed, because of the price point of this machine, the fact that it could do both MIG and Flux core, could add a spool gun to do aluminum, had all metal drive wheel assembly (which you don't normally find on cheaper 120 machines) and a Tweeko gun assembly.
I'm sure that I could have returned it and got another, but I wasn't willing to risk it down the road if something went wrong with it. I didn't want the heartache others had gone through.
Now I don't want anyone to think that this is a negative review of HD, because they were great. I also don't want people to that Longevity is all bad either, because this is MY first (and only) experience with it. I didn't have to deal with them directly, and after reading some horror stories off the forums, I'm glad I didn't have to. I WANTED to like this machine and this brand, but I only get burned once before I go back to my first instincts. I will save some more money and get the "old reliable" RED or Blue one. Hope this helps some of you avoid any problems, and make an educated purchase.
good price for a 140 amp welder
mine didnt work
