I have been soldering for about 60 years and still manage to make occasional
shity joint.  Teaching and observing others mistakes:

Relax.  Some of the pads are starting to lift.  This is usually from too much
pressure and heat.  Tension will do that. You never need to press tip hard.
The heat transfer is via molten solder.

Use biggest tip you can.  Clean it on Brass pad and not wet cellulose sponge.
Ever since I switched to Brass, my Metcal tips last forever.  The thermal
shock of wet sponge is hard on tips.

Flux.

I use a wet sponge, and my Metcal tips last for about a year each. I
mostly use a medium-size wedge tip. The little pointy ones don't seem
to last as long or stay as well tinned.

I guess the Metcal patents expired, so someone else makes cheaper tips
now. They seem fine too.

I use the brass scrubbers too, and my tips last far longer than with the 
original sponge, get a couple of years of daily use out of a tip...it 
seems to clean off the oxides and flux residuals better than a sponge.

I do not use metcal, but have a really nice temperature controlled iron, has even auto-shutoff,
sop you can forget to switch it off (very green ;-) )
Long ago I figured the sponges damaged my tips.
One day in a Tek factory I came across an assembly person who cleaned the tips by rubbing those over:
 A big blob of solder.

Fascinating, did some experiments myself, that works!
tips last forever.
These days I clean the tips after every solder action with:
 A napkin.
Same tips in use for 10? years, still OK, 
 http://panteltje.com/pub/soldering_iron_tip_cleaning_IMG_6610.JPG
  on the napkin you see what comes off ..
  the 'sponge' is dry and has a thick solder coating to rub the tips on.

The right hand one is my favorite one,
too pointy and thin is bad heat transfer,
too long is also bad heat transfer.

That's not actually due to my soldering; those were caused by the ever-
increasing heat of the original components on the run-up to their failure.

I have to say I'm really impressed by the quality of Tek's mid 1970s PCBs. 
Despite all my extended butchery, none of the traces lifted. Those were 
the days!

Yup, I did actually switch to a ball of brass wire for tip-cleaning some 
years ago.

Some professional soldering people do that far worse.

The only problem for me in a possible shortcut between the two 
connections of the rectyfier bridge, an insulation pipe should be welcomed.
It surely is the mains rectyfier, so a high voltage that could spike.

It's actually under 4V AC entering that "hand-crafted" rectifier.

OK, but a shortcut mai lead to some amperes.

If you want to learn how to do good soldering with "old"
and "unsophisticated" equipment, see the Pace Basic
Soldering Lessons.
https://www.youtube.com/playlist?list=PL926EC0F1F93C1837

In contrast to most of the wittering talking heads and
videos of printed pages(!) found on yootuub,
those are excellent videos:
  - short, because production and distribution of the
    films was expensive
  - to the point, because they are short
  - good on theory of what needs to be done, and why
  - good practical demos of what happens when you
    get it right - and wrong

The only major flaw is that it is difficult to suppress
sniggering at the pronunciation of "solder".

Of course CD won't see this message, because he's blocked
me. His loss :)
