Large Scale AC Resistance Weld Controls - Miyachi - #1

Text version of the page

Features • Primary and secondary constant current – provides closed-loop feedback and delivers superior control and improved welding results. • Built-in weld monitoring – the control will monitor the delivered RMS current for the weld period and conduction angle. Limits can be set and alarms generated if out of limits. • Dual Pulse with programmable upslope/downslope – upslope and downslope can be programmed for both Weld 1 and 2 to accurately control the heating rates of the materials and provide success with difficult welding combinations. • Voltage monitoring option card – when welding in constant current the RMS voltage can be monitored to provide a useful quality indicator. • Current stepping – a versatile stepping function allows the current to step automatically to compensate for electrode wear and ensure consistent welds. • Electronic pressure regulator and differential pressure monitoring option – force can be set electronically as part of the weld schedule, limits can be set on actual firing force. • Simple, intuitive programming – large LCD, logical software and push button layout allows easy programming and viewing of weld schedule information. resistance welding STA Series Single Phase AC Resistance Welding Control • Constant primary and secondary current feedback • Built-in current and conduction angle monitoring • Spot, seam and roll spot capability • NEMA style cabinet • Electronic pressure regulator option • Voltage monitoring option • Communication option Applications • Consumer appliances • Nut and stud welding • Electronic and automotive components • Aircraft components • Office furniture • Automotive sheet metal
