Why do you think the unit fails to operate in 2T mode using the Everlast variable green torch. Here is the video again. When I press and hold the button it stops welding at random times. I never take my finger of the button. It just stops. I am going to buy a cheap Harbor Freight helmet so I can use its lens to take video of the weld process. You will see that I never let off the button.
