Abstract :
A personal computer-based digital control system for gas tungsten arc welding (GTAW), which controls the ignition process, the arc length, and the process of welding termination, is presented. The arc ignition control, arc voltage control, arc length control, and arc termination control using the digital controller, the arc characteristics, and the welding process monitoring are described.<>
