Review on Weller D550 Soldering Gun Replacement Tips (7250W) - Pack of 2 High-Quality Tips by Brian West

These tips come with straight ends, not the "curved" ends of the tips they replaced. So I had to use an electrician's pliers to cut the ends off my old tips and reuse those draw bolts with these new tips, "bend" the ends on the new tips, put the new tips in a locksmith's vise and twist them hammer in . new cocks with a mason's hammer - that doesn't mean you can't think of a way too.
