Do have a Pegasus with an original Triton tank. Triton tank takes a lot of power to make them work. Mine on TC I set at 540F. You may want to start at about 450F and bump it up from their. TC not the greatest at switching on the Pegasus 2 with its auto change over. Pegasus 3 is coming with a menu that you can set to your coil. I have much better units for TC so my Pegasus is only used now with wattage. CHEERS!
