MTS211Si not feeding wire

[mts211si]

I moved the wire from the old board, but still no luck... same behavior. I've attached some pics in case anyone sees anything wrong. (Note: the black material covering the wire pad is liquid electrical tape. The original board had a similar coating, so I tried to match it.)




Thanks,
Kevin

Oleg exchanged several emails with me last night and sent me a marked up photo that showed me what to try next and it worked. I need to do some more testing tonight, but so far so good.

What did you adjust or mess with that worked?

[mts211si]

Oleg modified my photo showing some pins to jumper. If anyone knows why this works I'd be interested in knowing too. The old board didn't have it that way.



Thanks,
Kevin

I used a jumper like you'd find on a PC motherboard to connect the pins. I'll check things out some more once it gets a bit colder again. So far so good. Thanks again to Oleg for the support.

It is in the upper 30s this morning, so I figured I'd give the 211Si and it's new board another go to see if temp related issues are still solved... I only used mig, but it fired up and worked perfectly. I'm feeling pretty good that things are back to normal.

Quick update:

I did some stick welding yesterday, mostly to test out my diy fume extractor, and things went well. Today I decided to try .023 solid and flux core since I haven't yet with this welder and had old spools lying around. It turns out the welder wouldn't feed, similar to my original issue. It was a hair under 40° in my shop. I heated it up a few degrees and it started turning again, so I'll need to keep an eye on it.

Does Everlast know if I'm the only seeing this problem? Thanks.

Anyone?

I just tried it again at 36°F, but no joy. The updated board seems to help it work at 10-15° cooler, but it isn't a complete fix. Is this a design issue? Does Everlast expect this machine to work when the ambient temperature is 45° or lower?

Thanks.

Apparently it does not affect all of them. But it is apparently something to do with a cap. issue and low temp. I don't have all the info on this yet, but just was forwarded an email regarding low temp operation and "improvements" in the MTS from Duncan in China yesterday.

Is this a problem with all the MTS welders? I have an MTS250S and so far have not had this issue. Mine is in an enclosed trailer all the time with no heat and I have not had a problem . I did have this same issue with a Thermal arc inverter that I kept in the trailer. Last week I had to put it in a heated area and let it warm up before it would work.

In short...No. But you shouldn't have a welder in an unheated area, especially if the temps fall well below freezing.

As you get more details, I'd be grateful of you can fill me in. Thanks!

I will as I get info. But I am usually last to get updates on tech changes these days. I'll keep pressing for some additional info when Duncan returns.

You da man! Thanks again.

This not true. If that was the case half the work in the world would have never been done. If that were the case every manufacturer would have that in their manual .You are the first person in my life that I ever heard say that.

Gary,
They usually do.
Modern electronics. Screens etc can freeze. Capacitors too. In fact they do.
First from the lincoln 210 mp manual. The following is from your own unit's manual. Which is confusing as 0C is not 14F. Being a Chinese unit and translated from Chinese specs, I'd say it is probably 0C.

Well apparently another bug to work out.
Here is the second.

edit apparently not. Oh welll. It is there under "location"

I repair a lot of jeep ECMs where electrolytic capacitors have failed. They usually live 15 to 20 years under the hood, potted in silicone but the cap still reaches whatever the low temperature is outside.
I use plain old generic Radial type,35V 220uf, temperature range -40 to +105 degree Celsius (10 cents each). This temperature range seems to be the standard.

That says -4 degrees not not below freezing. I understand thet there are temp ranges for electronics but -4 degrees is a lot different than +32 degrees . I can go along with that but not 32 degrees. It also says it can be stored down to -40 Degrees.

Your manual for the TWECO 211 says 0 Degrees C minimum temp.
