Welding power supply for welding condition memory type CO2 / MAG arc welding machine

摘要

The present invention is a welding condition memory arc welding machine for securing welding quality in carbon dioxide arc welding, it is possible to set, memorize and call the welding conditions by applying a microprocessor, so that it is easy to manage the systematic welding conditions and to operate the remote controller at the actual welding place. The present invention relates to a welding power supply device capable of performing wire forward / back inching, gas check and welding current, voltage setting and monitoring, and the microprocessor 10 is requested to call a stored welding condition from a remote control device 5 or a welding condition. When the set value is inputted, the command value for the welding current and voltage set from the storage device 18, such as the welding condition memory area and the standard welding condition, is input through the digital / analog converter 14 or the torch starting switch and inching. Kettle circuit by welding contact signal of switch through digital port 13, welding start signal, gas check, and inverse inching Each output in the substrate 11, and; The detection signal of the welding current and voltage received from the kettle circuit board 11 is converted into digital values by the analog / digital converter 15 through the effective value detection circuit 16 and input to the microprocessor 10. The welding power supply of the carbon dioxide arc welding machine, characterized in that the actual welding results are monitored by the remote control device (5) through the digital welding current / voltage indicator (4) or the communication port (12) by the processor (10).
