Abstract
A shielded metal arc welding system includes a stick electrode holder, a stick electrode clamped by the holder, and a welding power supply operatively connected to the holder and configured to supply a welding current to the electrode through the holder. The power supply includes a memory storing both of a short circuit threshold voltage level and an arcing threshold voltage level. A welding voltage level is detected during an initial shorting of the electrode to a workpiece for commencing a welding operation. Both of the short circuit threshold voltage level and the arcing threshold voltage level are adjusted based on the detected welding voltage level. A short circuit clearing routine is activated when the welding voltage level is equal to or less than the adjusted short circuit threshold voltage level, and deactivated when the welding voltage level is equal to or greater than the adjusted arcing threshold voltage level.
