What is the Miller RHC-3CBI?

What's included with the Miller RHC-3CBI?

What kind of cord should I use to connect the RHC-3CBI to the welding power source?

What's the maximum amperage the RHC-3CBI can handle?

What's the maximum voltage the RHC-3CBI can handle?

How do I install the RHC-3CBI?

How do I adjust the amperage on the RHC-3CBI?

What's the amperage range of the RHC-3CBI?

What should I do if the RHC-3CBI is not working?
