It is a standard phase angle controller, like in a light dimmer. With high leakage transformers (such as a MOT), it can be used to control power, but also the RF envelope (shape and sound of sparks).

PS. Neat coil Patric smile

Thank you! I wanted a coil who can run for hours without overheating or danger for damage, not a super-coil.
