Need help finding a female socket for this Connector

I need Help finding a Female socket assembly to fit this arc relay switch from a Gullco Moggy . I am trying to make a lead up to connect it to a Unimig Envy Welder. it just outputs a trigger signal/closes the circuit through pins a and c. But just need a female circular socket to fit.

Hello,
Welcome to the DigiKey TechForum. I wasn’t able to find any information on the size of the connector you need. You can view these options to see if one will fit. You may want to contact the manufacturer of the machine to see if they will provide a part number or provide the specifications of the connector that could help us narrow down the list.
