PAS offers a wide variety of used ultrasonic welders, used heat stakers and refurbished equipment to meet your budget, as well as your assembly needs. All used ultrasonic welders are warrantied and ready to go. Our large inventory of ultrasonic welders also enables us to set up and debug tooling that we manufacture for you using the same brand of ultrasonic welders that you are using at your facility. When you purchase a new system from PAS, we offer trade-ins on your used equipment. Our inventory consists of many makes and models, including used Branson, used Dukane, used Sonics and Materials, used Herrmann, used Sonitek, used Forward Technology, used Mecasonic, used Ultrasonic Seal, used Thermosonic, used Sonobond and used Rinco ultrasonic welders so we are trained in the use of our competitors machines in order to meet every customer's individual needs.
