my son bought the first model Hitbox offered the MIG 250 a dc unit .
It welded, but No where close to my HTP 220 MTS.
I tested the amp output and wide open it would only put out 165 amps.
They also advertised that it accepted 8" rolls and they could not even be mounted. 8" rolls would have been outside the exterior of the box. I pulled the electronics and remounted the spindle lower and it did fit an 8" roll then. Just made me mad that even with pictures they wouldn't budge and just said 8 " rolls fit.
The diameter of the lead conductors is to small even for 125 amps imo. All that said it does work but It also had a tendency to drop out part way through a weld like the Voltage was dropping off and then surging back up.
That is Dirt cheap for any AC TIG.
I will bet they are exaggerating the output.
