The last four of my unit is 0910...

The wires that connect to the element have a reputation for having crappy connectors and wire.

I have had mine running pretty much 2-3 times a week for 1.5 years.

The first time it quit I was able to clean them and get new connectors and drive on.

This time the element and wires burned up.

I called MB and the element is on back order for 30 days....

So I cleaned what was left of the element and cut the wires back and cleaned them.

Wrapped  together and soldered.  Then duct taped evreything and put it back together.

It works...

Before..

Whatever it takes to keep stuff running... Good fix Craig.... Now that the connectors are soldered you probably won't have any more problems... Right !!!
 
I have heard of this being done before.    There has never been a follow up on how long the solder repair lasts.   Seems that the temperature generated by the heater would be sufficient to melt the solder off of the terminals.    Has anyone looked at a solder repair after it has been used to see if it melts or not!  Would think it would be a better than terminal fix if it stays put.

Enjoyed the joking around but on a practical view I wonder if this is a viable alternative to replacing spade lugs.    There are three MES's in my arsenal and I have replaced at least one spade lug on two of them at times.    I wonder if anyone in SMF land has had a long term experience with soldering the lead to the terminal?    My opinion is that the solder would melt away.   My other thought is to silver solder the thing together,  which takes a higher heat than tin and lead solder.

Just looking for a more permanent solution when this happens again !!!

Thanks!!

Take a look at the pics again...

The male portion of the element/lug is burned off.

I would definitely solder the connectors when new if I had known this would happen..

Fact is that the 60/40 solder I used doesn't melt until it hits 361 degrees Far.

Thanks Craig,

When the Calrod is glowing red hot and the heat is migrating out to where the spade lug used to be I am wondering what the temp is at the solder joint    Possibly 361 degrees or higher?

The next time I fire it up I will take the panel off and check the temp during use!!

well i repair autos for living my strong point is eletrical i've soldered a lot of wires it depends how well it was prept for solder the resistance in the solder joint can heat it up enough to melt it.
 
As an electrician, I doubt that the duct tape will last long on heating elements, and the solder questionable. I would suggest some type of pressure connector like a lug or even a crimp on.
