Ok, after overnight soaking the string in water, today i ran two spools worth of cutting .
The welding-melting happened only twice and it wasn't the string/head/trimmer fault. Ones i attacked a very heavy overgrowth too fast and another time there were thick twigs in the grass i did not see.
Looks like the trick works
Thank you guys, i knew i could find the right solution from you.

Curious situation; it sounds like it's related to ultrasonic vibrations moving up the trimmer line into the spool and presumably the vibrating lines against each other causing heat.

Yes, i red about it, but the question is, why the dried strings are more sensitive to it.

My guess is the dry ones are rougher and more susceptible to friction-induced heat.
Also, apparently the string does soak up some water, so perhaps that extra bit of water in them keeps them from heating too much... for a while.

Today i tried a cheap no name no brand string which i could not use at all. I left it overnight in the water and today i ran a full spool cutting and trimming without a single issue. Who would imagine such an easy solution.

I know the thread is old but I wanted to mention that my buddy is in the lawn care business and buys trimmer string on bulk rolls. He carries the string in his trailer soaking in a covered 5 gallon bucket of water. He says he never has issues with string anymore. Just sayin...

Skip to 0:17 if you are in a hurry. You're welcome.

We run 155 string and tested dry vers soaked. We can do this in the same head since they hold 3 strings. Didn't see any longevity difference.

Had this issue too frequently. When I switched to Husqvarna Titanium line this problem is all but gone. I am using a Stihl trimmer head (at one point I was threatening to replace it). When you load up the head you need to make sure you don't twist the line; a clean wind helps also.

What will exasperate this tendency is to be hitting really tough stuff a lot as this results in the line being tugged and that tightens the line inside the head and causes binding (line will be pulled down in between two adjacent wraps. The proper approach to dealing with heavy stuff is to drop down on it rather than cut into it.
