Abstract
A method and apparatus for welding is disclosed with a remote wire feed speed control potentiometer on a torch is disclosed. The range of the torch potentiometer is from a minimum to a value dependent on the control panel welding wire feed speed. A run-in wire feed speed control is also disclosed. The range of the run-in wire feed speed is from a minimum to a value dependent on the control panel or torch welding wire feed speed.
Claims24
A method of controlling welding system comprising:
- sensing a first wire feed speed input indicative of a first wire feed speed from a selector located on a control panel of a source of power;
- sensing a second wire feed speed input from a first selector located remotely from the source of power;
- controlling a wire feeder to operate at second wire feed speed setting responsive to the first wire feed speed and the second wire feed speed input.
A method of controlling a welding system comprising;
- sensing a wire feed speed setting from a selector located on a control panel;
- sensing a user selected run-in setting, wherein the user selected run-in setting has a range from a minimum to a maximum, and the maximum is dependent on the sensed wire feed speed setting;
- controlling a wire feeder to operate at a speed responsive to the sensed run-in setting during run-in.
A method of controlling a welding system comprising;
- sensing a first wire feed speed setting from a selector located on a control panel;
- sensing a second wire feed speed setting, wherein the second wire feed speed setting has a range from a minimum to a maximum, and the maximum is dependent on the first sensed wire feed speed setting;
- controlling a wire feeder to operate at the second wire feed speed setting.
A method of controlling welding system comprising:
- means for sensing a first wire feed speed from a selector located on a control panel of a source of power;
- means for sensing a second wire feed speed input from a remote selector located remotely from the source of power;
- means for controlling a wire feeder to operate at a second wire feed speed setting, responsive to the first wire feed speed and the second wire feed speed input.
A welding system comprising:
- power means for providing welding power to a weld;
- a first wire feed speed selector means, located on a control panel, for providing first output indicative of a first wire feed speed;
- a second wire feed speed selector means, located remotely from the power means for providing a second output indicative of a second wire feed speed between a first value responsive to the first wire feed speed and a second value;
- a wire feeder means for feeding wire to the weld, and
- a controller means for controlling a speed of the wire feeder means to be the second wire feed speed output, and connected to the first and second outputs and to the wire feeder means.
A welding system apparatus comprising:
- a means for providing power to a weld;
- a wire feed speed selector means, located on a control panel, for providing a first output indicative of a wire feed speed;
- a user selected run-in setting means, connected to the controller, for providing a user selected run-in output with a range from a minimum to a maximum, wherein the maximum is dependent on the first output;
- a wire feeder means for feeding wire to the weld;
- and
- a controller means for controlling the wire feeder means to feed wire at a speed responsive to the user selected run-in output.
