A nose clip is an important element of a face mask, as it enables the wearer to secure the mask on the nose and make sure the loosely fit mask covers the face and seal the contours. The nose clip can be welded onto the edge of the mask. In order to weld this nose clip, KN95 face mask nose welding machine is used. This machine can be used to weld together the face mask and metal nose clip. This machine is good for the masks that require the nose clip outside.
