Weller 7250W Solder Tip 5.5mm for D550/D650 Guns (2-Pack) - DIY & Electronics Repair

I was worried these might be low quality given that they were the "less expensive" version. However, they were correct, they fit my 250W Big Old Bertha Weller soldering gun perfectly. It has always been almost impossible to get the ends bent correctly so the tip comes out straight- I recommend putting a sharpie mark on each leg about 3/8" or so from the end so you have a reference. (without it, once one side is bent it's hard to judge where to bend the second to get a good match.) AND of course, put the boots on =before= you bend them ;^) If you try to straighten them back out they will break off, now you have a shorty tip. Most interesting thing was watching the entire thin silver colored plating instantly flash into a gray colored bubbled mess when I pulled the trigger the first time. But, I did not expect it to stay pretty, and it sure works great. Glad I got them.
