PURPOSE:To perform remote control simply and accurately and reduce the number of cables to improve productivity by installing a transmitter, a repeater and a receiver in a welding output remote controlling device. CONSTITUTION:A power source 10 for welding and a welding torch 12 are connected to a wire feeding device 11 through cables 13, 14. Welding output obtained from the power source 10 for welding is supplied to a base metal through a cable 15. A repeater 18 receives light signals such as near infrared rays sent from a transmitter 17 and sends receiving signals to a receiver 19 through 1-2 core transmission line 20. It is installed in the wire feeding device 11. A receiver 19 is installed in the power supply device 10 for welding, and controls change of welding output condition basing on signals sent from the repeater 18. |
