INVERTER BASED TANDEM SAW SYSTEM

Tandem SAW system is two wire one arc SAW process in which both DC and AC power is used for the two wires. Two independent power sources capable of delivering DC and AC is used in the system. The system offers high deposition efficiency when compared to single wire SAW system. We use inverter based power source for both DC and AC. The AC power source is capable of delivering either DC or square wave AC out put.

FEATURES

• Both DC and AC/DC power sources are IGBT inverter based with latest soft switching technology.
• Both Power sources are microprocessor based for precise control.
• High Energy efficiency and low volume compared to conventional system
• Higher power factor and precise out put and hence better weld quality
• Both power sources have CC/CV function
• Square wave out put in AC/DC power source with adjustable AC frequency, Wave Balance and AC Bias
• Digital control panel with digital display for Voltage, Current and trolley speed
• Wire Selection for different wire sizes
• Memory channel to store the data
