x-tronic 4000 soldering station

Maybe I'm missing something here? Kester and WBT solders are now the same formulations/fluxes, and I should believe Kester over WBT(regarding WBT's product)? Of course WBT will still perform at 700 degrees F. The issue is whether it will, equally as well at around 500 degrees F, which I(and others) have found it will. Happy soldering.

Rodman99999, Can you post link to recommendation from WBT - I could not find any. If they recommend particular tip temperature than I cannot argue with that, otherwise with the same melting point and most likely similar rosin I would follow advice of Kester since they specialize in solder (don't do anything else). I've used quite a bit of WBT 4%Ag solder and it solders perfectly with 700degF - pretty much the same as typical Kester solder.

Mr K- Actually; I've never seen any recommendations regarding temps, from WBT. I started using Wonder Solder about 15 years ago, and found it worked wonderfully at lower temps than I was used to. To me; that was desirable, as dielectrics(like Teflon)tend to release gases, when heated. That means the chemical composition is changing. Not something I wanted to do to the expensive cables to which I was attaching various connectors, or the RCAs going in a chassis. When I started using WBT; I never raised the temp and never had a problem. Kimber Kable recommends 750 degrees, when using Wonder Solder, but I've never experienced any problems at 500 to 550.

Rodman99999, Next time I'll try 550. Teflon can be really bad if overheated,especially large surface like frying pan. If I remember correctly it releases Fosgen - a gas that was used as chemical weapon.

Mr K- Absolutely NOT the kind of thing I want, hanging in the air about my soldering station. In this first reference; they mention that Teflon begins off-gassing toxic particulates at 464, and emitting six toxic gases at 680 degrees F(plus a few other tasty treats):(http://www.tuberose.com/Teflon.html) Next to a vacuum or air; Teflon has been my favorite dielectric(since the 80's). Many of the components I've soldered have been configured in a way that left them hard to heatsink, and I was always more concerned with the idea of altering the chemistry of the Teflon, than that of my own body(typical).
