| Abstract: | The electric parameters of the short circuit transfer of CO 2 arc welding are examined totally and systematically by using an advanced data collecting system controlled by a computer.Stadies and analysis of the above data show that the arc voltage can reflect the droplet short circuit and the arc re start,and its differential signal can indicate the pinch of the liquid bridge.This is a better foundation for developing the real time control of short circuit transfer of CO 2 arc welding. |

| Keywords: | CO 2 arc welding short circuit transfer real time control signal quality |
