Electrodes are available for welding carbon steel, low-alloy steel, stainless steel, and nickel-based alloys. Wire diameters vary from 1.6 to 6.4 mm (1/16 to 1/4 in.). Carbon steel wire usually has...

Although this close range is possible at temperatures below 675 °C (1250 °F), a more practical control range is nearer ±8 °C (±15 °F) for higher temperatures. In any temperature-control system, three steps must be executed. Before control can be established...
