Abstract

The subject innovation described herein generally pertains to a system and method for security features for a device in which functionality of the device can be limited or restricted in accordance with one or more security layers. To access functionality of the device, an appropriate security-related input is required.

First claim

What is claimed is:

1. A welding device, comprising:
a welding power supply configured to generate a welding output to an electrode to perform a welding operation;
a power source configured to provide power to the welding power supply for conversion into the welding output;
interface means configured to receive a security-related input data as at least one of an alpha-numeric data input by a user or a biometric data input captured from the user; and
controller means configured to:
verify the security-related input data as being valid for a security level configured within the controller means of the welding device; and
enable access to one of a welding function, to enable performance of the welding operation, or a management function, to enable performance of a supervisory management operation, in response to the security-related input data being verified as valid,
wherein the controller means is further configured to keep access to the welding function enabled for a configured amount of time, even when the welding device is turned off and on during the configured amount of time.

2. The welding device of claim 1 , wherein the security level corresponds to one of an operator security level, configured to allow the user to access and perform the welding operation, or a supervisor security level, configured to allow the user to access and perform the supervisory management operation.

3. The welding device of claim 2 , wherein the operator security level is for providing access to the welding device by the user when the user is an operator user, and the supervisor security level is for providing access to the welding device by the user when the user is a management user.

4. The welding device of claim 1 , wherein the controller means is further configured to disable at least one of the welding power supply or the power source until the security-related input data is verified as being valid.

5. The welding device of claim 3 , wherein the management function allows the management user to configure the welding device as part of the supervisory management operation.

6. The welding device of claim 1 , wherein the controller means is further configured to:
disable access to the welding function after the configured amount of time;
prompt the user for the security-related input data; and
re-enable access to the welding function upon successful verification of the security-related input data as being valid.

7. A method for a welding device having at least two security levels, wherein a first security level is associated with a first set of functionality of the welding device and a second security level is associated with a second set of functionality of the welding device, the method comprising:
receiving a request to access a function of the welding device;
prompting for entry of a security-related input data;
receiving a user input as the security-related input data;
determining whether the function requested corresponds to the first security level or the second security level;
verifying the user input as being valid for a determined security level associated with the function requested;
enabling access to the function requested when the user input is verified as being valid for the determined security level; and
keeping access to the function requested enabled for a predetermined duration of time after the user input is verified as being valid, even when the welding device is turned off and on during the predetermined duration of time.

8. The method of claim 7 , wherein the first set of functionality is a subset of the second set of functionality.

9. The method of claim 7 , wherein the user input is an alphanumeric code.

10. The method of claim 7 , wherein the first set of functionality includes functions related to using the welding device for welding operations.

11. The method of claim 7 , wherein the second set of functionality includes management and configuration functions.

12. The method of claim 7 , further comprising prompting for re-entry of the security-related input data after the predetermined duration of time elapses.

13. The method of claim 7 , further comprising maintaining the welding device in a disabled state of operation until the user input is verified as being valid for the determined security level.

14. A non-transitory, computer-readable storage medium having stored thereon computer executable instructions implementing security procedures for a welding device, the instructions, when executed, configure a processor to:
disable operation of the welding device pending entry and validation of security-related input data;
receive user input data as the security-related input data being indicative of a function request and an access code, wherein the access code corresponds to at least one security level of one or more configured security levels of the welding device;
verify the access code as being valid for the at least one security level;
enable operation of the function requested of the welding device when the access code is verified and when the function requested corresponds to the at least one security level, and
keep access, to the function requested, enabled for a predetermined duration of time, even when the welding device is turned off and on during the predetermined duration of time.

15. The non-transitory, computer-readable storage medium of claim 14 , wherein the instructions further configure the processor to disable operation of the welding device after the predetermined duration of time.
