Because of it's small size, it is welded to the tip rather than having a wire through it. Extra caution needs to be taken when using these tips, they stay hotter longer after they are unplugged. The larger sizes can stay hot for up to 5 minutes so please be extra cautious when using them. All ball tips require a longer warm-up time and cool-down time than our other tips.
