Awesome system. Follow the wiring diagram per the instructions. You may not get an output voltage reading at first, but when you attach your hotwire frame, the system will work as advertised! For a 33 x 0.032 saw, it got to optimal foam cutting speed temp at about 1/3 of a turn.
If youre building a Long EZ the plans call for a transformer with a 4A output. If youre cutting foam 64 in length per LEZ plans you may find the 3A maximum output insufficient: I burnt out the transformer from this kit while making some large cuts.
Burned up after 1 large airfoil cut.
