I connected mine all together for the first time, just this evening. It has been in the equipment cabinet in my shop, since I bought it last summer; never before tried using it.
It is doing the same thing as mentioned in the previous 2 posts. The torch lit for several seconds, and I actually made about a 3/4 to 1" cut partially through the 1/8" steel bar, but then it quit. The air is still delivered to the torch when the trigger is pressed, and the LED display still shows whatever you set the amperage to, but no cut arc. Not sure what's going on with these units, but it's disappointing.
I paid the extra charge for the 'warranty exchange' program, but I don't know if any of those extra units purchased for the exchanges, are still available.
I will read through the thread, and see if there is anything obvious. Meanwhile, if anyone has a suggestion of how to see if the warranty exchange program is still in effect, I'd like to hear from them. Thanks...
