This is an Accurate Tools ATPW 524 Plasma cutter and TIG/Stick Welder that I am selling locally.
I couldn't find anything about them online and there was only one video that had a different model, so I made a video of this one before it sold.
Here's a cheaper model on Amazon: amzn.to/3UuHks3
Retail on these is something like $350-$450.
Here I do some plasma cutting. I haven't yet tried out the stick or tie welding yet.
