Like this one?

Lotos LTP5000D 50Amp Non-Touch Pilot Arc Plasma Cutter, Dual Voltage 110V/220V, 1/2 Inch Clean Cut, Brown https://www.amazon.com/dp/B0052OX876/ref=cm_sw_r_cp_api_i_ERgeFbY03TMF8

Are you running it on 110 or 220?
Yup. 220 V. It won't do 1/2" on the lower voltage input. I've had no issues to date but it doesn't get constant use either. It will see some more work in the coming months. Clean dry air is very important for these machines.
