Inverter stik welder problems

[yomax4]

As for inverters. Many of the top brands do a much better job on how they dip and bake their PC Boards and seal fan bearings or bushings. Many are to Military Spec and will handle the storage you did with yours as long as they don't fill up with dirt and mice nests. You will pay more but you wont have to buy twice.

Always wondered why main brand companies such as Miller, Lincoln, Hobart, etc. charge over a thousand dollars for their tig/stick inverters of similar or even less amperage. Makes me wonder if there is an inherent thought process to some of the way more cheaply built Chinese stuff that they are simply "disposable" welders that might work from 1-5 years. Sort of like how auto manufacturers built cars from the 70's through 80's. I think it was GM who felt once your 82 Olds Ciera reached 60K, it was considered "done".

When Longevity was more active on this welding forum, there were a couple members who had their Stickweld 250s. Member Furu brought his welder to my shop for some one on one help. The machine ran great, but it took way more amps to run a rod compared to my other welders. Over a very short period of time the welder just kept losing power. Same thing for a kid who lives in British Columbia. Longevity replaced both welders. But Furu's new welder did the very same thing! So he bought a Everlast PowerArc 300.

I wish "hindsight" was more upfront.

Some of our more "resolute' members here on TBN that we sometimes "crack on" for being stubborn, may have more "frontal vision" at times regarding these things.

To play devil’s advocate, what are they supposed to do? The warranty has an expiration date because they don’t know how customers are going to handle the machines. They have to draw a line in the sand at some point, and yours happened to go bad after you crossed the line. It’s seems to be a safe bet that storing in the container played a big role, that really isn’t their fault. They were honest with you that it would cost more to fix than it’s worth, I’m not sure what else they can do. Surely you don’t expect them to pay to fix a welder that’s out of warranty, and that seems to have broken due to a poor storage choice?

Did you read post 33? You make a large assumption sir. Where does it definitively show that where I stored the welder is a "safe bet for it's failure?" It was an airtight case. No condensation. No temp differentials from inside to outside air, no infiltrating ambient air moisture. The concept of it being better "in the open air" is a ridiculous one to me as this is where the welder would have been subject to moisture way more than in the case. It wasn't anyone's fault except the designer of the welder to a price point.What do I expect them to do? Yes, forego their warranty limit on this one because it is absurd to think that a welder should crap out after being used 3 times within a year and half..To me, it is also absurd for them to lean on the "warranty" as you may think I should forego because of a time date. Perhaps they are the one's who should do that. If you could tell me something about mosfet design and why they might fail, then I'd give your Satan advocacy more weight.

I don't mind someone playing the "devils advocate" but not with unproven assumptions..

I use a welder every day to make money so it's important to me that it be reliable. A few years ago, I had a need for a Plasma cutter for a job and rather than spending my $1800 budget on a Thermal Dynamics or similar, I purchased a Chinese made invertor based multi-function device that would give me a 250A AC/DC TIG, 50A Plasma and 250A Stick. I've always wanted an AC/DC TIG but never really had a need for one so I thought this would be a good compromise. Well, the plasma worked for the job I got it for but a few months later had lots of problems with both it and the TIG, where they really just didn't work. The arc would die or not strike, it gave me codes, all kinds of problems. It was still under warranty so I called and after close to 2 months, finally got an RMA to send it in for repair. They had the machine for close to 3 months before I finally got it back and it was still doing the exact same thing. So I called, emailed, etc. again and got some response and then just got ignored, at which point I posted some online reviews which were seen by the owner who contacted me and offered me a new machine. By the time I finally got the new machine, it had been close to 9 months from the date of my first call. At this point, I'd lost all faith in it at all so I sold it on eBay for $1500 (losing about $500 on the machine and shipping costs) without ever plugging it in. Maybe the replacement machine would have been bulletproof but I wasn't willing to take the chance. The seller did ultimately do everything they could to solve my problem but since I use my machines to make money, the time it took just wasn't worth the cost "savings" in the end.

Since then, I've only bought name brand stuff with local repair facilities. One of the reasons that the name brand stuff costs so much more is not only that they're built for industrial use instead of hobby use but they also have the network in place to get machines repaired locally with parts support rather than sending them back. When one of my Lincoln welders went down, I dropped it off at my local welding shop and had it back in my hot little hands 10 days later in perfect working order. I still need to keep a backup machine but 10 days is a whole lot better than almost 9 months.

If you need a stick welder, as has already been mentioned, you'd be hard pressed to find anything better than the old Lincoln IdealArc tombstone welders. That's what I learned to weld on 25 years ago with a machine that was probably 40 years old at the time, and I'm sure it's still kicking in that classroom today. Watch your local craigslist, you'll find them on there anywhere from $200 - $500 and I can promise you that other than submerging it in a pool of water or burying it in the dirt, it will work every time you turn it on. Even the AC225 is a good little machine that can be relied on.

All this looks like a good reason to go out an hug my Tombstone. Around here it's nearly always damp and or cold and I just cant be bothered lugging my welder into and out of the basement to keep it working. It's not like you can heat and air condition your garage to keep electronics content. Besides, a lick with the grinder and a coat of paint and my welds look good too. That reminds me its about time to put my Handler135 in the basement until it's needed again, winter's a comin.

I live in the Seattle area. You guys may have heard, it rains here a bit!:thumbdown: My shop is not heated, all I do with my inverter welders is drop an old shop coat over them. My Miller Dynasty 300 is 10 or 12-years old. My Everlast PowerArc 200 is about 6-years old. They all work like they did on the first day.

I also live in the Pacific Northwest and have an insulated but unheated shop.

I have 6 inverter welders (5 Miller & 1 TA) , but due to an intimate understanding of Murphy's Law will decline comment.

You said yourself it was your fault, I didn't make one single assumption. Now you’re trying to back out of it. The “airtight” container was the most likely issue, just like you’ve said multiple times. I never said it was a definite, not sure what you’re talking about there. You bought a cheap welder, stored in a way you thought was sealing out the moisture but likely sealed it in, and now you want them to replace it for you even though the warranty expired. I’m sorry, but I think you just learned an expensive lesson.
