Inverter stik welder problems

[arrow]

A welder once related to me that lack of use can negatively effect transformer welders. I was wondering if this is can be true for inverter type boxes.
I purchased a little 140 stick welder from one of the advertisers here. I do not weld much at all but I wanted something that could. I used it a couple of times last year. Put it in a suitcase in a covered garage and took it out last week for a project. Well the thing had a completely different complexion. Last year it handled welding a cutting edge on a log splitter with no problem. This year it is having trouble starting an arc and sputtering with something as small as 3/32 6011's. Doesn't matter what rod I use, acts the same way (tough start and tough to keep going). Some of the digital read out bars have disappeared but this is no problem but it will not go above 125 amp read out even on a 220 circuit.
Contacted company 5 days ago with no return phone call as yet so i am asking here if lack of use can be troublesome. Thanks

After I wrote this, I went outside to play around with it some more. It seems there could be a read out problem opposed to actual output. Last year the thing ran beautifully on 115 amps for a 1/8" 7018 rod. Last session proved this to be a very "sticky" setting. It was hot enough, but sticking rods. (7018 on top of wood stove for 5 hrs). So on a whim, I jacked the reading up to 125 or as high as it would go (read out). Very little sticking and arc starting much more readily. This was on bare metal sanded with a grinder first as was the project. This goes back to my first question. Did the welder sort of "regenerate" itself the more it got used or did something go haywire with the readout amperage over the winter because I left it out in the garage? Just checking to see if anyone else experienced anything like this with their inverters.

Perhaps it's condensation that didn't dry out until you took it out of the suitcase. Probably not a good idea to store it that way.

I was doing some welding with a buzz box last week and ran short of rods. Ran up to the local auto parts and picked up a pound of 3/32" 6011. (What I was using when I ran out.) First spark and bead was crap. I looked at the sleeve and sure enough, made in China. I made a couple of procedure changes and finished the work but I'll never buy that stuff again. I'm glad all they had was a one-pound sleeve of the stuff. I might have bought more. I'll have to remember where I bought the original rod and stock up.

Most of your name brand filler is made in China now, and some of the best running MIG wire is made in China. I've run some US stuff that was pretty lousy. Where it is made doesn't have as much to do with it as the composition of the wire.

Arrow, not remembering if you bought from Everlast or not, but if you did, pm me. If you didn't that's ok, I'll still try to give you some information. Leaving a piece of electronic equipment out in a place that is exposed to the elements can, even though you are protecting it in a suit case, wreak havoc. Where you are things can get below 0 and cold I assume. Things can freeze up like capacitors or displays. Corrosion can enter the picture, and even in cold temperatures, it could theoretically cause soldered joints to contract at a different rate than the board or wire that are applied to causing separation. Just some theories,, that I wanted to offer to be helpful or at least give you a possible insight to what i going on. But again, if it is ours and you dd not get a call back, pm me your number, and we'll get on it.

This stuff was not "name brand". I'd have to go out to the shop and look but it was called something like FlashFire, FlashBurn or something of the sort. Probably some literal translation. That's about all it did was flash. Even the coating was a different color. It looked like redwood sawdust.

I got it from a locally owned auto parts that in the past only sold the best and catered to the area farmers as far as stocking sideline materials. They still use paper catalogs and hand written receipts--No computers. I should have known things would change after the "old man" passed away last year. It's the kind of auto parts I remember from the 50s and 60s. They could get you anything. Small towns are loosing their edge.

You can clamp a set of DC tongs ( meter ) over your ground cable and test true output. Also double check your polarity.

Thanks Mark. I specifically did not name a brand so as to not unnecessarily disparage a particular company product for something I might have caused. I kept the welder in the heated cellar for all of the time. I then did a project last fall and left it in the garage over the winter. Of course the welder was always under cover but if cold can effect them, then cold did it in. I will take your advice, put it in a Tupperware container and keep it in the cellar.
No matter who I bought it from, the onus seems to be in my court.

Polarity was the first thing I checked. Can a AC/DC voltage meter be made to relate anything in this regard or does it have to be a dc clamp meter?

Well it seems that indeed because I did not use the welder much at all and the fact it was kept in an unheated garage, moisture that ordinarily would have been evaporated by use just got to sit in all the little connections and mosfets and eventually flaked up the welder.
The kicker of it is that to "fix" the welder costs more than I payed for the thing and not by a little bit. Makes me wonder why I didn't buy a transformer welder as the total cost to replace the welder with a new one more than equals the cost of an original transformer.

If you live in a climate of humidity or variations of heat and cold or you do not have a heated shop or garage be careful where you keep your little inverter if you do not use it much.
