Hi folks,
    Wellers were subject of a similar thread on another list a wk or 3
ago.  Many folks have had problems, some have managed to overcome or at
least live with some.
    Here's my procedure -- tin the ends of the tip, before bending them,
hopefully b4 the old one burns thru.  This does help considerably.  Also,
if it's one with lamp(s) for illumination, the lamp(s) must be tight in
the socket(s).  I still do re-tighten the tips occasionally, but not often
after the first time.  I've been using Wellers for almost 50yrs, first one
when in high school.
    Hope this helps.  But the can tab on the chassis is a tough one no
matter what you use.  Sometimes you have to break the tab, and hopefully
there're still some left to hold it in if you re-stuff & re-use it.  You
can see my re-stuff method at:

  Thanks to all for your fine suggestions. I was very close to simply
soldering capacitors in underneath the chassis on my T-4XC, but I tried
once more with the Weller soldering gun. I used a wire brush on the entire
tip (even where it attaches to the gun) and was able to desolder the tab
within a few seconds.

    Eric,

    You indeed have discovered the problem, not enough heat. Both those
devices you tried were totally inadequate, not because of temperature, but
of extremely low thermal capacity. You might have to go to a 200-300 watt
soldering iron with a BIG tip and then you'll be ok; they have enough heat
capacity for just such jobs. As an alternate, but this is marginal, you
might try a propane torch BUT WAIT, what you do is heat the tip up to
temperature, then turn off the gas, and use it immediately to desolder the
tap with Solder-Wick. It may or may not work. The large soldering iron is
what works for me.

    Work safe.
