PURPOSE:To improve work efficiency by preventing destruction due to an overrun by displaying on a CRT the coordinates of the teaching point of the torch tip of a welding machine which corresponds to each step number, and the extent of a margin up to a limit. CONSTITUTION:A CPU9 is connected to a numeral arithmetic part 9, and also connected via common signal line L to a control program memory 10, a position memory 11 for a torch 20, an input and output control part 12, a CRT control part 14, and a positioning control part 16 for the torch 20, thereby driving a robot body 19 and the torch 20 in accordance with a program. The conditions of welding are inputted from a teaching box 18 and a keyboard 13. When the torch 20 is moved to a command position and the button of the teaching box 18 is pressed, the coordinates of a current position and the extent of a margin up to an overrun limit calculated by the numeral arithmetic part 8 are displayed on a CRT15 through the CRT control part 14. Consequently, trouble due to an overrun is prevented to improve work efficiency. |
