ARC WELDING APPARATUS, ARC WELDING SYSTEM, AND ARC WELDING METHOD |
| 摘要 |
An arc welding apparatus includes a difference calculator configured to calculate a difference voltage value by subtracting a welding voltage value from a target voltage value; a speed setter configured to set an advancing speed and a retreating speed of a welding consumable with respect to a workpiece to increase a ratio of a magnitude of the retreating speed to a magnitude of the advancing speed corresponding to an increase in the difference voltage value; and a driver configured to drive the welding consumable at the advancing speed and the retreating speed to generate a short circuit condition and an arc condition. |

1. An arc welding apparatus, comprising:
a difference calculator configured to calculate a difference voltage value by subtracting a welding voltage value from a target voltage value; a speed setter configured to set an advancing speed and a retreating speed of a welding consumable with respect to a workpiece to increase a ratio of a magnitude of the retreating speed to a magnitude of the advancing speed corresponding to an increase in the difference voltage value; and a driver configured to drive the welding consumable at the advancing speed and the retreating speed to generate a short circuit condition and an arc condition. |
