WELDPRO-4.0 RF (radio frequency) welding, is also known as dielectric sealing or HF (high frequency) welding, is the process of fusing materials together by applying radio frequency energy to the area to be joined.  The resulting weld can be just as strong as the original materials. WELDPRO-4.0 is designed for welding thermoplastics such as PVC (polyvinyl chloride), EVA (ethylene vinyl acetate),PU (polyurethane), PETG (polyethylene terephthalate glycol), polyolefins. Controls • Four stages of the welding cycle with independent time and power settings • Measurements and displaying of the output power and the input power • Product counter • Working, setting and diagnostic mode • Safety switches (emergency stop and press up)   WELDPRO-4.0 shown with Press, Automatic Shuttle, & Safety Light Curtain      Dimensions • Generator - 21" x 13.5" x 19.7" - 534 x 342 x 500mm • Matching Section - 23.6" x 15" x 8.3" - 600 x 380 x 210mm AC Input • Voltage • Frequency - 200-400 VAC - 50/60 Hz   Power Consumption • Idling • Max - 150W - 5kW Air Pressure - 43 PSI (3 bar)   RF Output • Power • Frequency - 0.1-4.0 kW - 27.12 MHz (based on crystal oscillator)   Features • Power-MOS transistor   output • No tube replacement =   lower operating costs • Precise solid-state RF   power control • Single cycle or   continuous welding   mode • Fully automatic RF tuning • Microprocessor control   circuit • Self diagnostic   capabilities • LCD display and keypad   as interface • Build-in arc suppressor Options • Touch-screen panel • Manual tray shuttle • Automatic tray shuttle • Safety interlock switches Typical Applications • Medical • Packaging • Industrial applications WELDPRO-4.0 Brochure (PDF - 1,233 KB)
