Soldering irons with 2 power levels

2 power levels

— the ability to set two power levels on the soldering iron — full and reduced. This feature is especially popular on plastic pipe models, which are very powerful, but not all of this power is always required. These tools work most of the time at a reduced level, but the full intensity of heating is used only when soldering large diameter pipes. In other types of soldering irons, usually, the opposite is true: the standard mode is full power, while reduced power is used for delicate work and heat-sensitive components.
