Abstract

Disclosed example power supplies, user interfaces, and methods are provided for intuitive or automatic control of welding parameter output ranges. The disclosed systems and methods provide tools for setup of configurable and/or default settings for a welding power source and/or wire feeder. Weld settings include upper and lower limits for an operating range corresponding to one or more welding parameters, such that a welding parameter value is bound by the upper and lower limits during a welding operation. In some examples, the operating range, and the corresponding upper and lower limits, are calculated or determined based on a selected range tolerance.

First claim

What is claimed is:

1. A welding system, comprising:
a control circuitry to control a power source based on a range of values associated with one or more welding parameters, the control circuitry configured to:
receive a selected range tolerance from one or more range tolerances associated with a selected welding parameter value of the one or more welding parameters;
calculate an upper limit value and a lower limit value for the range of values based on the selected range tolerance, the selected welding parameter value, and a welding parameter type of the one or more welding parameters associated with the range of values, the calculating comprising:
receiving a selected range value associated with the selected range tolerance;
receiving a welding parameter modification value associated with the welding parameter type;
calculating a first predetermined value and a second predetermined value by modifying the selected range value using the welding parameter modification value;
adding the first predetermined value to the selected welding parameter value to calculate the upper limit value for the range of values; and
subtracting the second predetermined value from the selected welding parameter value to calculate the lower limit value for the range of values; and

control the power source to deliver power based on the range of values and the selected welding parameter value.

2. The welding system of claim 1 , wherein the one or more range tolerances comprises a strict range tolerance, a standard range tolerance, or a broad range tolerance.

3. The welding system of claim 2 , wherein the controller is further configured to adjust the range tolerance between a low limit of the strict range tolerance and a high limit of the broad range tolerance in response to an input.

4. The welding system of claim 3 , wherein the input is a change in a welding parameter of the one or more welding parameters.

5. The welding system of claim 3 , wherein the input is an operator input from a user interface, the user interface comprising one or more of a knob, a touchscreen panel, or a dial.

6. The welding system of claim 2 , wherein the strict range tolerance is more narrow than the standard range tolerance, and the standard range tolerance is more narrow than the broad range tolerance.

7. The welding system of claim 1 , wherein:
the control circuitry is further configured to calculate the upper limit value by adding a first predetermined value to the selected welding parameter value;
the control circuitry is further configured to calculate the lower limit value by subtracting a second predetermined value from the selected welding parameter value; and
the first predetermined value and the second predetermined value are different.

8. The welding system of claim 1 , wherein the control circuitry is further configured to calculate the upper limit value and the lower limit value by:
adding a first percentage of an absolute value of the selected welding parameter value to the selected welding parameter value; or
subtracting a second percentage of the absolute value of the selected welding parameter value from the selected welding parameter value.

9. The welding system of claim 1 , wherein the one or more welding parameters further comprises a second welding parameter, the welding parameter selects the range tolerance from a first plurality of range tolerances of the one or more range tolerances and the second welding parameter selects a second range tolerance from a second plurality of range tolerances of the one or more range tolerances, the second plurality of range tolerances being different from the first plurality of range tolerances.

10. The welding system of claim 1 , wherein the one or more welding parameters includes one or more of voltage, current, power, wire feed speed, gas flow rate, pulse rate, workpiece thickness, workpiece material type, electrode type, welding process, travel speed, arc length, or joint type.

11. The welding system of claim 1 , wherein the control circuitry calculates the upper limit value and the lower limit value by:
accessing a list of welding parameter values associated with the welding parameter type, the list of welding parameter values comprising listed upper limit values or listed lower limit values associated with respective welding parameter values;
comparing the selected welding parameter value to the listing of welding parameter values; and
determining at least one of the upper limit value or the lower limit value based on the welding parameter values and the listed upper limit values or the listed lower limit values.

12. A welding system, comprising:
a power source configured to deliver power to a welding tool based on one or more welding parameters;
a welding wire feeder configured to advance a wire electrode to the welding torch based on the one or more welding parameters; and
a control circuitry to control the power source or the wire feeder based on one or more ranges of values associated with the one or more welding parameters, the control circuitry configured to:
receive a first selection for a first selected welding parameter value associated with a first selected welding parameter of the one or more welding parameters;
receive a second selection for a second selected welding parameter value associated with a second selected welding parameter of the one or more welding parameters;
receive a selected range tolerance from one or more range tolerances associated with the first selected welding parameter and the second selected welding parameter;
receive a selected welding process type from one or more welding process types;
calculate a first upper limit value and a first lower limit value for a first range of values based on the selected welding process type, the selected range tolerance, a first welding parameter type of the first selected welding parameter, and the first selected welding parameter value, the first range of values corresponding to the first selected welding parameter value;
calculate a second upper limit value and a second lower limit value for the second range of values based on the selected welding process type, the selected range tolerance, a second welding parameter type of the second selected welding parameter, and the second selected welding parameter, the second range of values corresponding to the second selected welding parameter value, wherein:
a first ratio of the first upper limit value to the first selected welding parameter value differs from a second ratio of the second upper limit value to the second selected welding parameter value;
a third ratio of the first lower limit value to the first selected welding parameter value differs from a fourth ratio of the second lower limit value to the second selected welding parameter value; or
the first ratio differs from the second ratio and the third ratio differs from the fourth ratio; and

control the power source to deliver power or the welding wire feeder to advance the electrode wire based on the first range of values, the first selected welding parameter value, the second range of values, and the second selected welding parameter value.

13. The welding system of claim 12 , wherein the control circuitry is further configured to:
designate the first selected welding parameter value and the first range of values as a customized welding parameter setting; and
store the first selected welding parameter value and the first range of values in a list of values associated with one or more customized welding parameters.
