| Abstract: | The paper designed the hardware and software systems of an inverter type CO 2 arc welder by microprocessor MC68HC11E1.The items controlled by digitalization are as follows: preset and display of welding parameters, sequential control,selection of wire types and diameters,arc start and crater performances,cable resistance detection,etc.All the preset and feedback variables were set by microprocessor.The droplet transfer cycles were controlled by wave control method.Also gradual adjustment of the sequential and wire feed rate was controlled by software.The reliability of system was improved by measure of anti-interference.The system enhanced the intellectual level and adaptability of welding inverters. |
