摘要
A method of sensing and controlling an arc welding process employs a high equency rate of sampling of electrical signals from the welding circuit. The sampled signals are operated upon by predetermined processes to determine electrical resistance, shielding gas quality, and short circuit frequency. The process measurements are compared to a predetermined set of tolerance levels and evaluated using a window technique that updates the evaluation of the data samples at the sampling rate.
