do you sell a crimp or tool to attach the 2 different wire types of the type k thermocouple wire to make a good junction that will be reliable connection going hot and cold and condensation? Or do you provide a service to spot weld the ends together?

Asked by: Tom C
Hi Tom C, Thank you for the inquiry. We do not offer tool for making junction other then our welder. We do not offer welded option. Suggested method of termination and use is to use a terminal block or connector to mate to a pre welded wire or probe style TC. Best regards OMEGA
