Smith,
I suggest you increase the iron temperature to 400 degC (750 degF).
The other suggestion I can offer is to use 63/37 allow solder (eutectic)
with a mildly reactive flux (such as Kester 287). Save the large
diameter Kester 44 (highly reactive flux) for antenna work and other
jobs where
I usually go between 370C and 400C or about (700F-750F) for most jobs.
Setting your iron to low will mean that it will take longer for the
solder to melt and giving more time for the heat to travel into the
component and possible damage.when working on boat-anchors with

Hi!
I 375 to 400 C (700-750F) for normal soldering. When using wick (which acts
like a heat sink) I step up the temperature to the 800F (425C) range.
A hot iron will *not* damage your board or components. What *will* damage
the board or components is leaving the iron in place for too long. Time
Actually, the conversion is easier to remember than those two formulas.
The two scales coincide at -40 degrees.
So for the conversion (either way) first add 40.
Then if the conversion is from Centigrade to Fahrenheit multiply by 9/5
(you will be going to a greater number), but if the conversion is

Or, in google just type something like: 750F to C
Works for all kinds of different units of measure.

Or of course, use a converter program on your smart phone!!!

I just push the switch on my Weller and watch it change from F to C.
I love simple. Hehehehehe

Another trick, you can do C->F in your head:
Double the centigrade temperature, subtract 10% from the product, and add 32 to
get Fahrenheit.
10 degrees C = (2*10-2) + 32 = 50 degrees F
F->C is not so slick, but works:
Subtract 32 from the Fahrenheit temperature, add 11% of the result to itse

I try to minimize the number of formulas I need to remember.
This one has served me well
1.8C=F-32
Replace the known value, and solve for the unknown.

It won't work for SMD stuff, but over the years I've had great success
using a classic Ungar 27W cartridge (which I seem to remember was around
850°F) with a screw-ON 1/8" screwdriver tip for just about everything
but the heaviest jobs. This includes lots of building stuff with
