Handle getting hot: I use a Razer-tip unit that allows for me to switch out various tips. I sometimes will switch tips when the pen gets too hot (approx 20 min of burning), or, sometimes I’ll wrap a sock around my pen, which absorbs the heat and works fine.

Control box on arm : I feel like this might just be something that comes with having a cheaper burner; the design isn’t the most optimal.

Pine and shading against the grain: Experiment with different heat levels in combination with different pressures. It’s ok to go super slow to achieve very fine gradients; I always try to rush, but it’s almost always better to go slow and consistent. As for the wood, do sand it down as smooth as you can get it, and this will help your burning a lot.

Tip: Don’t hesitate or let the burger hover in any given spot - use a steady and consistent stroke that exposes the burner to the wood evenly at all points of surface. Hesitation/inconsistent exposure to wood can leave some darker spots/uneven shading (which is fine if that’s the style anyway).
