How to I use this Everlast torch.

[Judgeless]

When you select do1 in program 8 of the background menu, it allows you to select the special 4T mode which allows you to ramp power up and down after the switch is released the first time and upslope has finished doing its thing. The range of control(welding amps) is set on the panel and the torch will control the amperage from the minimum set amperage up to the selected welding amperage.

I did that. I have it set in the hidden menu option 8 now to 1. It now lets me select 4T mode. It does not let me use the rolling knob to change the current. Do you think my 210EXT is bad for the torch Everlast sent me is bad?
