I have an Everlast 210EXT and it came with a bonus AMP control torch. It shipped with the wrong gas connector. I finally took the time to buy a new connector and clamp so it works with the 210EXT.

I assume the best way to use it is 4T mode. I also assume when the variable knob is turned all the way up. You press the button and it starts the ARC, then when you release the button it runs the weld at target AMP setting. If you move the knob it turns down the AMP setting.

On my 210EXT it will not let me select 4T mode when this torched is plugged in. It does let me select 4T with the default Everlast torch. If I changed the hidden menu (D8) to 1 it lets me select 4T.

When I try to use the variable control it has zero effect. What is the best way to use this torch?
