Pulse technology is typically an important feature found on more premium steam iron models. Pulse allows users to control the amount of power that comes out of their device, thereby allowing them to remove creased clothes without having to apply too much pressure or do it very quickly. This can be especially useful when you are dealing with thicker fabrics like wool and denim since they require a shorter amount of time than regular non-wool garments for de-creasing purposes. However, if not used carefully, pulse features sometimes lead to damage caused due to excessive heat so keep that in mind before using it every time you wish to press your clothes.
