today was over 100 degrees and i was out mowing and whenever i had to bump the head on my redmax 2600 to get more line out, it wouldnt come out so every time i would have to take apart the head and separate the line that had "melted" together. i had most of the problems come after doing a long fence line or edging (high rpm's for extended time) i am using echo cross-fire 0.95 and a redmax 2600. any ways to get rid of this? i hasnt happened since now. does the outside temp effect this???

Make sure you wrap your line in as perfect as a spool as possible. Keep the line as long as you can. Avoid catching the line on objects, especially the fence. What happens is you create tons of friction and heat in the line on objects that grab at the line instead of cutting against a surface like a wall. The shorter the line the quicker the heat makes its way to the spool without the heat dispersing.

why isn't this tip posted on the 'TIPS, Do's and Don'ts tips for the new guy' thread? Very good info.:cool:

This condition is commonly called trimmer line "welding" and results from ultrasonic resonance of the line within the spool. It can happen with any type of line, but is more prevalent with round shaped line than with square or hexagonal line. The ambient outside temperature does not significantly contribute to line welding. Line welding is encouraged by: sustained high speed trimming against a hard stationary surface (fences, curbing, walls, etc.) and wrapping the line on the bump head spool in a rotationally twisted manner. You can minimize line welding by using a lower head speed when trimming against hard objects and varying the throttle speed. It also helps to let the line hang free and rotate the spool around the line when loading the spool. Most people hold the spool stationary and wind the line around the spool. This technique tends twist the line rotationally which causes the line to bind and fuse together due to the ultrasonic vibration.

The line I buy has chalk on it. In the past 15 plus years, My line only seized up maybe 5 times. Reason poor wrapping of the line. Also, using echos cross fire may have something to do with it. Correct me if I am wrong. But Round wire has more mass per surface plain than say triangular, star style pattern. So sure crossfire my cut quicker but wont last as long. With the sharp corners on the wire, will cut into the wire itself, causing wire to stick/melts/weld/ gull together.

TIPS:
Also, if some may not have figured this out yet. Do away with trimmer line spool holders, that you put on your open trailer. The sun will cause the wire to become brittle. Keep out of sun. Pre-cut wire to length and wrap around an object in which you can take off after you put a little zip-tie on it. The object shoudl be a lil bit bigger in diameter than your spool holder. The wire will then hold its proper, arc, and helix. Doing this will save you time and money!


I hope this helps you.

To save the time of wrapping problems, I bought a couple extra spool heads for my trimmer and I keep them wrapped and in the glove box. One goes empty and I dont have to spend time in the hot sun fighting to wrap the spool. quick change and go. I can wrap spools in the comfort of my shop listening to the radio with the fan blowing on me.

Same here. I keep 3 pre-spooled heads for each trimmer in my toolbox in the bed of the truck. All my winding is done at home.

Try Not To Put The Line On The Spool To Thight. That Seems To Help For Me.

We always had that problem with Redmax, doesn't happen anymore we now use all Kawasaki.

The Redmax trimmer head has a grease fitting. If you keep it greased then it will stop the heat build up. I had the same problem.

echo crossfire line does this more often than others. I bought three five pound spools from a guy last year and it happened a couple of times a week. this year I found a deal on gator line and it hasn't happened even once.

My Kawasaki was doing it. Of course that was with cheap line too I guess, went back to my Arnold Extreme .080 and haven't had any more problems (so far).

We had that problem using Echo Cross Fire line. Now using Rotarys" .095 twisted line and haven't had a line weld on us yet. The trimmers run wide open most of the time as well. We keep 6 pre spooled heads in the truck, so line is always fresh and not brittle.

Oh yeah....after spending 28 years in Houston I had to come back here and do my part and help with cause. Did you spend some time here, or maybe come down for South by Southwest?

After wrapping it give it a spray of fluid film!!!!:weightlifter:

Try to find a separated / divided spool to fit your trimmer.

this morning i...
1. rewound the spool not as tight and made sure the line didnt cross over itself
2. greased gearbox above head
3. used a little less throttle
4. ran the string longer.

sadly today was still 100+ degrees but i had not problems at all. thanks guys:clapping: :clapping:

How do u keep these extra heads from unspooling, I don't see how you can let them sit. If I let a finger off them when I am reloading then unspool like mad.

Try dripping some engine oil on your line spool, I did this by accident and no more welding, I spilled a bunch on my 3 lb spool 2 years ago and it still is fine. And it is in a truck box, not in the sun.

Try spraying your freshly wound spool with wd40, silicon spray, pam, etc. I use cross fire 095 and never get weld back since learning about the spray. Give it a try.
