The Vertrod PS Direct Drive impulse bar sealer welder is designed for heavy duty sealing applications of thick or high-temperature materials requiring long seal lengths and higher pressure than the standard PS. The PS Direct Drive is generally used in manually fed packaging or impulse welding fabricating applications but can also be utilized in conjunction with more automated machinery. This impulse welder is capable of making hermetic seals with temperatures ranging from 200 ºF to 650 ºF. The welded structural steel tubular frame provides the stability necessary to make seals up to 120" long and seal widths up to 1" wide. Open back construction allows the user to operate this impulse welder from the front or rear of the sealer as well as providing pass-through ability for an uninterrupted flow of film. The PS Direct Drive impulse sealer employs PAC’s state of the art solid-state control circuitry along with an improved safety system.
