.25 Mild Steel Settings with a RazorWeld 45

oh and yes the ground clamp is attached to the material …do i have to change other settings now that i shut off the thc? or will they just ignore them
and I found another thread and changed the Razorweld over to 2T instead of 4T and still nothing. Andy disconnected the plasma gun and we shut off the control box and he used the torch manually at the other end and it worked! so now what do we look for?
