Equipped with an adjustable temperature controller, our KF-CS direct heat sealers allows the user to control the amount of heat needed for different material types. A 5-15 minute warm up time is required to achieve the correct temperature. The sealer is constructed of durable metal with insulated rubber hand grips. Also included with each sealer is a stand for setting your sealer while not in use. Please DO NOT touch the jaws of the sealer until it has cooled down.
