Abstract
PURPOSE:To obtain the welding quality equal to that of model welding despite the consumption of tips and the generation of disturbance by performing the model welding, storing the inter-tip voltage during welding, and controlling welding output in such a way that said inter-tip voltage is generated in a guarantee welding process. CONSTITUTION:Welding is carried out under standard conditions and the signals corresponding to inter-tip voltages of arbitrary groups are stored into the memory 11 of a microcomputer 9. Thence, the 2nd test welding is carried out at the output smaller than this, and the signal corresponding to the inter-tip voltage of an arbitrary cycle is stored in the memory 11, and the difference thereof is operated, from which a proportional constant K is determined and is stored in the memory 11. Guarantee welding is carried out under the same conditions as those in the first test welding, and the stored voltage of the memory and the detected voltage at the guarantee welding are compared and operated with a computer 9. This signal is fed to a thyristor controlling circuit 16, which prosesses this by incorporating welding data, sequence control, etc., and sends a thyristor firing signal to a thyristor 1, whereby regular welding is accomplished.
