ACE TOOLS CO.,LIMITED 10 PCS Weller ET Replacement Soldering Tips for WES51/50,WESD51,PES51 / 50,LR21 Solder Iron Tip, ETS/L/KN/T/U/R/A/B/C/D (China Made brand"ACE")

Las puntas son de muy buena calidad y ajustan perfectamente en mi cautin Weller WES51, las puntas que he probado no he tenido ningun problema.

First off: I'm primarily a hobbyist. I'm sure that a professional will have drawers full of soldering tips for every occasion. And I'm sure that there are plenty of companies that will happily sell you a diamond-encrusted nano-coated extreme platinum limited military edition for the cost of a new car.So I can only speak to my own, admittedly narrow needs.I've been really bad about maintenance of my soldering iron over the years. The reason that I bought a Weller in the first place was to have tight control over temperature and an overall better end product.And then I stuck with the OEM tip. For years. Recently I needed a fine tip for some precision mounts. So I had a novel idea and figured I'd just get a variety pack and start actually using the appropriate tips for the appropriate jobs.Crazy! Right?It came and I busted out the 0.2mm bent conical tip for the one task that I needed it for. My biggest surprise was that I had to crank up the temperature a bit in order to get any flow. But then I realized that the laws of physics are still a thing and that more heat was needed due to the smaller surface area.I seasoned the tip, ran it through some shredded copper and got to work.Solder flowed, electrons were connected, and there was much rejoicing.And just for grins I decided to try something that I had never been able to do successfully. I tried hand soldering an ESP32 MCU onto a prototyping board. And after about 20 minutes of hunched over swearing, I closed my eyes, offered a prayer to the USB gods, and plugged everything in.And it worked. I know! I'm as surprised as you!It's entirely possible that any new fine-point tip would have enabled me to get everything working. Maybe this set is terrible and that any *real* professional would rather solder using a magnifying glass and the sun than to even gaze upon them. But over the past few days I've run most of them through my painfully amateur tinkering workflow and everything is still both hunky and dory. So for my modest needs, they're perfect.The 0.2mm and 0.6mm conicals, and the 4.6mm knife have proven to be the most useful of the bunch (for me at least).Overall I'm happy. Though I definitely should have picked up something like this when I had initially purchased my iron. Live and learn.My unit - Weller WESD51

Muy buen surtido de piezas. Excelente calidad del material con el que están fabricadas. Muy precisa la medida. El recubrimiento de las puntas de muy buena calidad . La adherencia con la soldadura sin plomo muy pareja. Totalmente recomendables.

First impressions were good. I measured them with calipers and compared them to the Weller product and they were within .005". (The Weller products varied .003" from each other). Then to tinning them, and they all accepted solder easily and evenly, without any voids. (Remember to tin any tip at the lowest temperature possible to prevent oxidation of the tip material before the solder gets to flow on it.) The heat regulation seemed good as well (I believe the heat sensor relies on the magnetic properties of the tip changing with the temperature of the tip.) All in all, it's nice to have such a wide variety of tips, since I work on anything from surface mount chips with the pins on .025" centers to hand wired 1930's tube radios. As for longevity, time will tell, but they come from a country where there is a LOT of hand soldering going on, so the need for quality soldering tips is very high. Hopefully these are part of that supply.
