Yeah, dunno. My soldering station is 48w and max temp is 450°C, I would think that's enough grunt. Though I don't know I've ever tried the braid with the 4mm chisel tip. I'm embarrassed to say I only started using chisel tips a few years ago. They make a huge difference.I think you need a very hot or powerful iron though. I’ve seen it work very well on some YouTube videos, but have failed with it myself, probably due to not having a powerful iron with a big enough tip.
