After adding the diode converter is ready for use?
Only, after you make your "wild" wiring solder connections correct.
In my looking at the 4 wires soldered to the circuit board
that were being made by the
FACTORY worker,
I only approve of the quality of workmanship on the positive
output wire.. . . . .and I believe that your iron burned the insulation
on the negative wire.
And will it provide me 600mA rather than 500mA?
Yes it will, but it is
IMPERATIVE that the 7806 has its heat sink firmly clamped to it.
AND ALSO a film of heat sink compound being between the mating tab of the 7806 and
the heat .sink.
That may be hard for you to find, unless you contact another hobbiest or electronics
service person in the know for the Islamabad supply situation .OR you might check out
plumbing suppliers as they use silicone grease on O rings associated with water faucets.
It is typically packaged and labeled like this:
Soldering:
If you can still loosen the two top set screws and pull out the soldering iron tip, examine it to see if there is a built up black oxide scale (which would be heat insulation) on the surface of the tip that is inside of the barrel of the irons heater. .
( it may also be inside the barrel of the iron itself. . . .MANY multiple side by side scrapes of a screwdriver cleans that out, )
If finding black oxide on the tip itself, file or wire brush down to unoxidized metal again.
Go to the blunt end and saw/grind off some length, so that the presently protruding tip will then be 2/3rds of its present length, doing that will get more intense heat out to your tips end.
You loose heat transfer in a
HURRY on long tiplets.
Also, it looks like you have your irons tiplet properly and adequately tinned.
One thing that will help immensely is to have a just moist cellulose sponge nearby.
Just before you are going to make a solder connection, pull the tinned soldering tip across it and immediately add a bit of fresh solder to the tip and immediately move right over to the soldering connection to be made.
The fresh solder aids in maximum heat conduction into the work area and THEN you just add the required amount of solder . . .to the heated work . . . to complete your solder joint.
