摘要： A method and apparatus for welding include a source of power, a wire feeder and a controller. The controller sends control signals to the wire feeder and the source of power. The controller also has an adjustable arc control input, and the controller controls at least three welding parameters in response to the arc control input. The arc control input may be an arc width input, and the controller may simultaneously control at least three welding parameters to obtain a desired arc width. The at least three welding parameters may include at least three of peak welding current, background welding current, pulse width, and frequency and the arc control input may be a user-selectable input.

摘要： A method and apparatus for welding, and particularly for clearing a short while welding is disclosed. If a short occurs, output current is increased from a first magnitude to a second magnitude and the short is monitored. If the short has not cleared after the current has reached the second magnitude the current is increased to a third magnitude. The difference between the second and first magnitudes is less than the difference between the third and second magnitudes. The current may be is increased from a fourth magnitude (which may be the normal operating magnitude) to the first magnitude before the increase to the second magnitude. The difference between the first and fourth magnitudes is less than the difference between the third magnitude and the second magnitude. The current is increased to the second magnitude only if the short has not cleared after the current is increased to the first magnitude.
