The torch you have is a lower quality version of the wp 17 we have online.

But if you didn't know, we have a 400 mts.

I am not sure if you are aware, but the MTS series are all DC.

The old 200P's weren't exactly using the same "amp" scale we use now. Compared to the new one, you'd find about 160 amps true output...from my understanding. The 200MTS puts out a lot more than you think.
