Abstract:
A method of controlling arc welding, which method shifting the speed of welding operation continuously and mildly. By so doing, a sharp change in the speed of weld wire supply, which is caused as the result of efforts to try to comply with an abrupt change in operation speed, can be moderated. This helps keeping a welding operation under a stable control.
