Bought this small plasma cutter to cut up some scrap steel I have collected and can say it is a great little unit. Setting at 25Amps I cut up the entire F650 cab into manageable pieces all on one electrode and one tip. I have run both industrial wayer cooled plasma units and the name brand air cooled units in the past and can say this is a grcat unit for the home shop. Would I cut 1/2" plate, no but for light stuff this unit is great! I would recomend to run it on 240V like I did. I have a 5 hp air compressor and it was able to keep up Jo problem only running about 1/3 of the time.
