***Shotmakers****

For those who make shot have you had your burner go? Three or four years ago I had the OEM burner arc on my shot maker. The wires were they meet the burner, the insulation had deteriorated around the wire. I was told there is no life expectancy for a burner from the manufacture of my shot maker, and has never had one burner fail. If this were true why is there replacement burner available?

What I need to know is do burners eventually not produce as much heat when they get older? 10tenner
