Title:
WELDING SYSTEM AND COMMUNICATION METHOD OF WELDING SYSTEM
Document Type and Number:
Japanese Patent JP2016059942
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a welding system capable of performing communication more accurately than in a case where a signal is superposed between two power cables.SOLUTION: A welding system A1 includes: a welding power supply device 1; a wire feeding device 2; a welding torch 3; a power cable 41 for connecting the welding power supply device 1 and the welding torch 3; a power cable 42 for connecting the welding power supply device 1 and an object W to be processed; a power transmission line 51 for connecting a power supply part 21 that the wire feeding device 2 has and a power supply 12 for the feeding device for supplying power to the power supply part 21 that the welding power supply device 1 has; a power transmission line 52 for connecting the power supply 12 for the feeding device and the power cable 41; and a power transmission line 52' for connecting the power supply part 21 and the power cable 41. The welding power supply device 1 and the wire feeding device 2 perform communication superposing a signal between the power transmission line 51 and the power cable 41.SELECTED DRAWING: Figure 1
