For those vaping 10 watts and over, remember that we use 10 to 25 watt soldering irons to melt solder and service delicate parts on some mini circuit boards. As long as your coil is fully wetted, it shouldn't be a problem, but consider the warning on the charts for the pink ranges.
"Power level may melt nichrome wire or solder"
At really high wattage part of that vapor may not be coming from the PG or VG. Then there's silicone seals that hold the wire to the bottom contacts. I've seen burning occur where the wire touches the silicone. Let's hope that it's charred juice. The nichrome wire can get red hot from one end to the other, not just around the wick, if it isn't in contact with something to sink the heat.
