INSANELY HOT DIY Hot Air Soldering iron @ 15 Volts DC and 3.5 amps...PART II

Step 23 Electrical insulation

This is how i solved the housing problem inside the unit...the spring pushes everything up nicely against the nozzle. The flexible insulation tubing seen here adds further protection of the power leads from the main spring. The perfect wire I found was butchered from an old metal halogen light fitting. It was thick and insulated and heat resistant. I held a lighter to the wire I salvaged and it did not burn, melt or smoke...excellent. It even had the ring connection on one end that is exactly the same size as the ones shown previously at the ends of the white and blue wires. Because the wire is so thick, it actually was used to push everything flush against the nozzle, kewlies
