Preliminary Information
Document Scope
This manual is a guide for the initial setup, adjustment, operation and routine maintenance of
the Vante Model 3120 RF Generator (hereinafter referred to as “the Generator”) used with
the Vante Model 3807 Large Sized Tube Sealer (hereinafter referred to as “the Sealer”). This
information is based upon technical data that is believed to be adequate for the intended
Sealer use.
Intended Audience
This manual is for use by personnel with technical skills, a thorough knowledge of the
procedures for using radio frequency (RF) power to seal, form and/or weld RF reactive
thermoplastic materials and the understanding that this sealer is to be used at their own
discretion and risk in a controlled environment. A controlled environment is a location
where there is RF radiation that may be incurred by persons who are aware of the potential
for exposure.
Application
The Model 3120 RF Generator and Model 3807 Sealer create a system for making seals on
tubing made of RF-reactive thermoplastic materials such as polyurethane, polyvinylchloride
(PVC), Ethylene vinyl acetate (EVA), certain types of nylons and certain co-extrusions.
Tubing may be filled with liquid; however, the outside of the tubing must be clean and dry.

1. Description
1.1 Tube Sealer System
1.1.1 The RF Forming/Welding Sealer System is a portable system which employs radio
frequency (RF) to seal, form and/or weld RF reactive thermoplastic materials in a
variety of tubing sizes. The Model 3120 RF Generator is the foundation of the system.
It must be connected to the Model 3807 Large Sized Tube Sealer to complete the
system and perform the required operation.
1.1.2 The system includes a cable assembly used to connect the Generator to the Sealer.
This cable assembly consists of an 8 ft. RF Cable and airlines for connecting the
Generator to the Sealer and air supply.
1.2 Theory of Operation
1.2.1 The physical properties of RF-reactive thermoplastic materials cause them to
dielectrically heat at a molecular level in the presence of RF energy. This energy
causes the plastic to soften due to the friction of the vibrating molecules. In this
softened condition, the plastic becomes weldable because the molecules are free to
intermingle under the application of external forces, such as compression. If allowed
to cool while the forces are applied, the weld will be permanent.
1.2.2 The RF Generator is the instrument that produces, when actuated, a controlled amount
of RF energy. The Sealer mechanically compresses the tubing across its diameter
during the sealing and forming process. When the RF energy is removed and the
tubing is allowed to cool under compression, a permanent seal is produced.
1.2.3 The RF Generator produces a variable nonlinear RF power output up to a maximum
of 200 watts, the frequency of which is controlled by a solid-state oscillator/amplifier
operating at 40.68 mHz. The RF power level, dwell time and clamp time can be
adjusted by the operator, allowing various tubing sizes and materials to be
accommodated.
1.3 User Safety
1.3.1 The Sealer is intended for use by personnel trained by their organization for using RF
equipment to seal or weld plastic tubing or parts in a controlled environment.
1.3.2 Vante RF Sealers meet or exceed appropriate electrical safety standards and pose no
electrical shock hazard when used with properly fused and grounded outlets.

Reference the Radio Frequency System Safety Considerations section included at the
end of this manual.
1.3.3 The Model 3120 Generator has a thermal protection circuit which will cause the unit
to shut down if internal temperatures exceed 55°C. After a short period of time
(when internal temperatures are below 55° C) the Generator will reset and operation
can resume.
1.4 Sealer Interface
1.4.1 The BNC Connector is located on the right side of the front panel of the Generator.
The three port quick release air lines connector is located to the left of the BNC.
The 15 pin D-sub connector is not used with the Sealer.
