Abstract
A low voltage system and method for servicing welding equipment including a service tool that may provide a low voltage power source to the welding equipment, enabling the welding equipment to be tested in a low voltage mode of operation. The service tool may also run various test sequences on the welding equipment operating in a low voltage mode of operation to troubleshoot and diagnose any issues with the circuitry of the welding equipment.
Claims20
A service tool for servicing a welding-type power supply, the service tool comprising:
- test leads configured to connect to one or more circuits in the welding-type power supply;
- a power supply circuit configured to supply a low voltage power to the welding-type power supply operating in a low voltage mode of operation via two or more power leads;
- and
- a control circuit configured to measure one or more aspects of the one or more circuits in the welding-type power supply via the test leads while the welding-type power supply is in the low voltage mode of operation, the control circuit being configured to:
- provide a test sequence to a first one of the one or more circuits in the welding-type power supply via the test leads,
- monitor a response of the welding-type power supply to the test sequence via the test leads, and
- compare the response to a reference response to determine whether the one or more circuits are operating properly.
