Someone wrote that they give two stars because there were no assembly instructions. I have to say if you can't figure out how it fits together then don't use the soldering iron it's holding, you're a hazard to yourself. On the opposite end of the spring loaded item holding the soldering iron is a bent one Piece of metal that fits into a slot in the top of the black base just above the area that holds the sponge. You can just push it in with your hand, take a small screwdriver and hit it all the way with a hammer and it will never come out and you're done. It holds my W100pg soldering iron perfectly, and at 700 degrees you need a good stable soldering iron. I have always been satisfied with Weller products. Peter
