I bought a Weller WCL100 soldering station a week or 2 ago and I've had nothing but problems using it. Every single time, the tip oxidizes and becomes unusable within minutes. I kept it tinned. I cleaned it after each use. I did everything I thought was correct(it worked fine on my other Weller 40w) and still lost 2 tips to blackness/oxidation. I tried turning the heat down and that didn't help, either. Anybody got any tips and tricks to keep the tips from oxidizing and burning up so quickly? At this point, it's almost gotten to me turning off the iron after each soldered joint, then turning it back on for the next one. I'm using whatever the solder is that came with the Weller kit. I didn't have this problem before I got the soldering station, using the exact same solder. Using my other 40w iron plugged into the wall worked fine. So I can solder without destroying a tip. Makes me look at the sponge they sent with it and the base station itself. I'll try a different sponge to clean it next time and plug straight into the wall and see if it still happens. Until then, what do you all do? Do you use separate Flux or Flux core wire? What about tip tinner? It says using tip tinner can rehab blackened tips so I just picked up a can to try it and see. If it helps, I'll use it. So what about you all? What's your standard setup to solder? Do you use separate Flux? Tip tinner? Anything else? Thanks.
