Profile: Nisburner, LLC is a manufacturer of pyrography and electronic woodburning systems. In our nisburner, RCA jack connector has more actual surface contact for a solid connection. All nibsburner's woodburning systems come with one or two cords. Our standard cord is 16-gauge & is manufactured to our specification for the best desireable woodburning done between 2 and 6 on the heat control dial. Our light duty cord is for burning at lower settings on the heat control dial. Our woodburning handpieces are hard-wired to the cord. This eliminates one connector & allows the heat directly to the replaceable tip woodburning handpieces.
