Abstract
A system and method is described for updating firmware in a welding or plasma cutting system. A removable memory device containing updated firmware code and a set of execution instructions is interfaced with one or more component boards. The execution instructions are executed on a processor of the welding or plasma cutting system to load the updated firmware code stored on the removable memory device into memory of the welding or plasma cutting system via an interface, generally overwriting the old firmware code.
Claims25
A torch system, comprising:
- a removable memory device consisting essentially of memory, an interface coupled to the memory, an update stored on the memory, and installation instructions stored on the memory, wherein the installation instructions are executable to install the update onto the torch system when the interface is coupled to a mating interface at the torch system.
A torch system, comprising:
- a torch power unit, comprising:
- a power supply;
- a controller coupled to the power supply;
- a memory disposed on the controller;
- a firmware stored on the memory;
- and
- an interface configured to receive a removable memory device to update the firmware stored on the memory without a portable computing device and without a remote network connection to the torch power unit.
A component of a torch system, comprising:
- a controller;
- a memory disposed on the controller;
- a firmware stored on the memory;
- and
- an interface configured to receive a removable memory device to update the firmware stored on the memory without a portable computing device and without a remote network connection to the component and the torch system.
A method, comprising:
- interfacing a removable memory device with a torch system without a remote network interface and without a portable computing device, wherein the removable memory device comprises memory and an update stored on the memory;
- and
- installing the update into the torch system to update the instructions.
