I have always used the cut40d plasma cutters. I really like this model even better. Having its own built in air compressor makes it even more portable. It cuts great on 220 volts. I use 220 because it has more available power. The consumables for this product are easily available on eBay. I find this product to be very user friendly. Even the torch head is replaceable on eBay in abundance. The price is way lower than the competition. A great all around bargain
