Introduction
All things soldering or should I say sodering gar damn
Mine
Here is mine. [Hakko FX-888d]
Manual
Temperature
On the video it 400°C for lead free 450°C
Soldering a Resistor Wire
I used to want to melt the solder onto the joint but you need to heat the joint, in this case a resistor wire and the pad on the board together.
Then add the solder
This is what finished looks like with resin around the outside
In this example, the person heated the pad and wire for 8 seconds before applying solder
Joining Wires
When joining wires, tin the wires first by heating the wire and then adding the solder.
Add Heat shrink one end and Hold Wires in position
Next join the two wires together
Tools
One recommendation was a PCB holder. You can buy these at [Jaycar]. These are small than they look and $25 NZD
App for Resistor Band. Resistor Toolkit

Polarity
Some components require you put them the correct way around as each end has a different such as ICs. This means the +positive and -negative ends matter. Printed Circuit Boards will indicate which way either by specifying pin 1 or by specifying the polarity.
Most of these I would recognised as having polarity. e.g. IC or LED or Diode but the capacity was not known but I was unsurprised. The trick is to check.
