PURPOSE:To prevent defective welding even if welding is interruptted in its middle, by storing welding conditions at the point in time of the end of welding in a storage part for all welding start instructions. CONSTITUTION:A CPU10 is connected via a command signal line 1a to a program memory 11, a number position memory 12, a welding condition memory 13, an input and output part 14, a positioning control part 17, and a welding power source control part 19 to drive a robot 2 in accordance with a program. Working conditions are inputted from an instruction box 7 and a condition setting switch 15 through the input and output part 14, and a work start and a stop command are inputted with buttons 8a and 8b. When welding is interrupted with the button 8b upon occasion, welding conditions when the welding is interrupted are stored in the welding condition memory 13. Consequently, even if the welding is interrupted at any time, the occurrence of defective welding is prevented. |
