A lead bench guy told me I was soldering too hot, changed my whole process
During a bench repair on a King radio at KPAE last Tuesday, he pointed out my joints had that dull, cracked look and said I was cooking the insulation before the solder flowed. I backed my iron temp down from 750 to 650 and started tinning the wire first, and my rework rate on old wiring harnesses dropped noticeably. Has anyone else had a simple tip like that totally shift how you approach a task you thought you knew?

That tinning trick is huge on old harnesses because the flux is usually long gone by the time you get to it, so the solder just sits there and you keep cranking heat to force it. Pre-tin both sides and it flows at lower temp, which means the wire never gets hot enough to wick insulation up under the jacket.
