Abstract
Welding controller 1 has CPU 1a, ROM1 1b, ROM2 1c and RAM 1d. Programs and data are written into the ROM1 1b and can be rewritten. Sequential welding data is written into the RAM 1d and can be rewritten. A write program for writing programs or data or sequential welding data into the ROM1 1b or the RAM 1d is stored in the ROM2 1c. When a welding control program or data or sequential welding data is input into the CPU 1a from an input device 10 or a computer 12, the CPU 1a executes the write program to write the inputted program or data or sequential welding data into the ROM1 1b or the RAM 1d. Preferably, ROM 1b is an in situ programmable memory, such as a flash memory or EEPROM.
Claims19
A welding controller comprising:
- a processor,
- a first memory coupled to the processor, wherein the processor is adapted to operate based upon a welding operation computer program stored in the first memory, wherein the first memory is re-programmable, and
- a second memory coupled to the processor, the second memory containing a write computer program adapted to write computer programs or data into the first memory, wherein the processor is adapted to execute the write computer program when a computer program or data is input into the welding controller from an external source.
An apparatus comprising:
- welding electrodes,
- a welding transformer coupled to the welding electrodes,
- a switch coupled to a power supply and the welding transformer,
- a processor coupled to the switch,
- a first memory coupled to the processor and containing a welding control computer program, wherein the processor is adapted to control current supplied to the welding electrodes and movement of the welding electrodes based upon the welding operation computer program, wherein the first memory is an in situ re-programmable memory, and
- a second memory coupled to the processor, the second memory containing a write computer program adapted to write computer programs or data into the first memory, wherein the processor is adapted to execute the write computer program when a new welding control computer program or sequential welding data is input into the processor from an external source.
