Ma Cai · Electric Welding Machine · 2000
A integrated control circuit adapted for SCR arc welding power source by using TCA785 SCR phaseshift trigger integrated circuit chip has been developed. The control circuit are comprehensive of Synchronous detection, phaseshift Pulses formation and Protection in one piece. In addition, it has strong anti-interference ability, easy assembling and debugging, Hence it is a high performance-cost ratio integrated trigger circuit.
