Copeland... I just ran my first batch of nut grade in my latest replacement generator. What a difference!! I bought 50 pounds from a welding shop in northern IN, and I'm already seeing another trip to acquire more
Definitely take the time to get the right fuel. Miners grade is not want you want to run through these things.
As far as Kentucky, I'm not familiar with any place there, but I know Carbide Industries, LLC is located in Louisville. They don't sell directly to the public, but I'm guessing that acetylene tank filling operations run at a cheaper rate due to their close proximity... Call around. It took me less than 10 minutes and 3 phone calls to find some in IN
