signal knob

On the basis of one-knob linear regression analysis, the unified adjusting of CO_2 welding current target signal and welding voltage target signal has been realized by using hardware circuit, and welding voltage target signal can be fine adjusted.

在一元线性回归分析的基础上，应用硬件电路实现了CO2焊接电流目标信号与焊接电压目标信号的一元化调节，并且具有焊接电压目标信号的微调功能。

Regression equation shows that one-knob linear regression coefficient for welding current target signal and welding voltage target signal in CO_2 welding process will increase with an increase in ( welding) wire diameter, but constants of regression equation will decrease.

回归方程表明，CO2焊接随焊丝直径增加，其焊接电流目标信号与焊接电压目标信号的一元线性回归系数增加，回归方程的常数项减小。
