Thank you for the compliment.
You are absolutely right about putting down a sheet on the bottom, I just didn't have anything floating around at that time, but I do now.
As for the 200DX, although I am not a welder and cannot compare it against anything else, all I can say is that I am enjoying it very much. Where I see the drawback is the actual cable between the torch and unit. Its quite stiff and large. The new blue and red machines have the gas flowing within the cable and the connector is a quick disconnect for the gas.
I am looking at upgrading to a better and more flexible cable, but I have to figure out how to make it work. I also bought myself a smaller #9 torch with the flexible head. I am using that one more than the 26 that was sent with the machine.
The other issue which may or may not be an issue is that the fan within the unit is quite loud. Other than than.... you will enjoy the machine.
Cheers
Richard
