介绍了一种基于MC56F8013单片机控制的逆变式直流弧焊机的设计方案。实验表明:这种弧焊机实现了对弧焊机的内部温度控制的过程、焊接时电流动态反馈调解的过程,而且这些过程和电焊起弧控制以及故障显示方面可以以数字化的方式显示在弧焊机上,本设计还解决了传统弧焊机焊接控制精度不高的缺点,一定程度上实现了焊接控制的智能化及数字化。该设计方案主要介绍了弧焊机的控制原理和主要电路。
A design scheme based on MC56F8013 single chip microcomputer inverter DC arc welding machine is introduced. Experiments show that the arc welding machine to achieve the internal temperature control of the welding process, welding current dynamic feedback mediation process, and these processes and welding arc control and fault display can be digitally displayed in the arc Welder, the design also solves the shortcomings of traditional arc welding machine welding control accuracy is not high, to some extent, to achieve the welding control of intelligent and digital. The design scheme mainly introduces the control principle and main circuit of arc welding machine.
