120V Harbor Fright FCAW

I have a 120V Harbor Freight inverter flux-core wire welder that I was going to sell. I bought it to dissect and hopefully convert to battery power (~160V battery) but discovered that the circuit topology is not suitable for such. Before I sell it, is there any demand for me to bring it to races or to donate it to PRS for trackside use? Fully working and has seen less than a minute of welding (verifying the hf product actually works before voiding any warranty it has).
