Licoln 210 MP on 240v shorted out?

[RNeumann]

I left it with both my cords. Funny thing is the guy on the phone told me the Tech told him "it welded fine on 230 but wouldn't weld on 110".

I suspect he has that backwards.

How come a "110" receptacle reads "122"? How come a "220" receptacle reads "244" (cause 122 x 2 = 244...duh).

I did ask the electrician about my service being higher than the 110/220. He said it is not unusual and that there is an acceptable range of voltage that everything should work in as consumers can't control what the electric company provides.

Kind of explains why the welder says one cord is for 120 V and the other is for 230V. I had wondered how one was supposed to make 230 out of 120 x 2.

It’s just old school slang. The goal voltage is 120/240v. Most and code would say that you should be within a few percent of that.

Btw- if I made/lost money for every correct/incorrect TBN diagnosis I’ve made I’d be up at least $0.05 after this one!!!! Haha

My guess is that you either suffered the failure of the autoranging switch mode power supply or some other circuit component downstream of the input power supply. In the latter case, such a failure likely would have occurred eventually regardless of the input voltage used. If the welder is under warranty I知 sure Lincoln will take care of it.

yes, this happens sometimes, especially on the cheap welders like this.. poor QC..

No, this happened a lot on their older much more expensive units as well...the ones built in Italy.

ok, so they have a continuing QC problem they never addressed, and it seems they don't care about then.. perhaps Miller is better..

Even if Lincoln wave solders the boards themselves in the US it is unlikely they also manufacture all the discrete board component parts. And likely those component sources change over time based on factors like cost and availability. The good news is you have a sole source warranty that they honored.

I agree, but you just have to hope that a failure occurs during the warranty period, but, you can always spend a few hundred more on an extended warranty, and be covered in the case other defects show up during that extended warranty...

In my experience, these type of problems surface early or they don't surface at all. This was the first time I tried to use the welder on 240 V power.

I'm pleased they are covering it with warranty, disappointed that it has been in the shop over a week now.

I wonder how warranty issues are handled with brands that don't sell thru dealers. Do the major guys cover shipping or is that on the consumer?

It's not just your experience, it is a very well known characteristic of manufactured items. It's called the "bathtub curve" because it sorta looks like a bathtub - high at the beginning of service life (failures referred to as infant mortality), drops off sharply for a long stretch and then turns back up (wearing out). That's why relatively short warranties are not really too bad most of the time: If it's defective, it should fail quick, and the warranty will cover it. The problem happens when you buy something but don't use it for a stretch...

It seems that statistically with electronics failures will occur within the first 10 hours.

Believing that I never purchase extended warrantees and so for so good.

"Bathtub Curve", a phrase I'll use in the future. Thanks.

It can happen with any manufacturer. Most important thing is how they deal with it. Prompt repair or replacement is the standard of a good company.

Resolution time will tell volumes about a brand.

Somewhat, but, if you have counterfeit capacitors in your unit, they could last a year or more, then, suddenly quit, manufacturers have been known to put 1 or more counterfeit capacitors in their equipment.. usually, the top of a capacitor will bulge, or the bottom of the capacitor will leak a tan fluid,(the electrolyte).. counterfeit is meaning the manufacturer partially copied the formula for making the capacitor illegally, but, forgot an anti-foaming agent is needed to prevent foaming of the electrolyte, which makes the capacitor swell, and lose it's electrolyte..
