No references found			The Sub Arc DC 650 and Sub Arc DC 1000 are optimized for the sub arc process while providing air carbon, arc cutting and gouging, stick, and flux cored capabilities. Power sources for the sub arc process by Modern Applications News At its height, four Divisions were involved, including a team at Applied Physics (now Industrial Physics) who adapted a plasma arc process (like that used in arc welding) to destroy ozone-depleting substances such as halons (once used in fire extinguishers) and CFCs (the banned refrigerants). Emission reducing technology pays off by Ecos The technical approach modeled the details of the arc process as comprising the following nine unique sets of variables: peak current, base current, rise time, falling time, wire feed speed, arc voltage, waveform response time, pulse mode, and pulse frequency.
