| Abstract: |
| This system makes use of the characteristic of low duty cycle of spot welder to limit the general energized capacity of a spot welder group at any time within a pre-set limit. Thereby, it stabilizes main voltage and welding current,and enssures welding quality of the welder group.The principle and significance of the system are introduced in this paper.The communication method of one timer with the control system,and its example with KD7-1 timer are given.The master-program and some sub-proograms are discussed. |
| Key words: spot welder limiting capacity group control system |
