<p>PURPOSE:To set a welding parameter with high accuracy by outputting the welding parameter and a welding command to a timer contactor and a sequencer respectively by a controller to control the operating procedure of the timer contactor for the sequencer. CONSTITUTION:A working end 2 of a welding robot 1 is moved by a driving means 6 so that a welding gun 4 comes to the welding position. At this time, the controller 7 outputs the welding parameter to the timer contactor 9 via a line 11. Moreover, the welding command is brought out from the controller 7 to the sequencer 8 via a line 10. The sequencer 8 gives the concrete operating procedure of the welding to the timer contactor 9 in order of the time. The timer contactor 9 controls the time, an electric current, etc., for every operating procedure according to the welding parameter and actuates a pressurizing cylinder 3 and the welding gun 4. Accordingly, the time for setting the welding parameter, etc., is saved and the setting with the high accuracy is made possible.</p> |
