1. A welding power supply comprising:

  • power conversion circuitry configured to convert an input power into an output power for a welding operation; and

    control circuitry comprising a memory, wherein data representative of a security key is stored in the memory of the welding power supply during manufacture of the welding power supply, wherein the control circuitry is configured to;

    control operation of the power conversion circuitry;

    pair a portable electronic device with the welding power supply by joining a mesh wireless communication network, wherein the mesh wireless communication network comprises a ZigBee network;

    based on determining that the portable electronic device possesses requisite security keys to access the mesh wireless communication network, coordinate loading of instructions onto the portable electronic device to configure the portable electronic device for operation with the welding power supply; and

    wirelessly communicate with the portable electronic device via the mesh wireless communication network,wherein access to the mesh wireless communication network is secured by verifying the presence of the security key stored in a memory of the portable electronic device and the memory of the control circuitry prior to the pairing of the portable electronic device and the control circuitry,wherein the security key is not shared between the portable electronic device and the control circuitry via the mesh wireless communication network during the wireless communication or when joining the mesh wireless communication network, andwherein the presence of the security key is verified during each wireless communication between the portable electronic device and the control circuitry.
