I bought this plasma cutter to see if something this inexpensive would work and was completely surprised. Not only does it work, it works with pleasure and cuts anything to 1/4 inch. without problems. I've used it to cut thicker materials, but only for testing purposes. I have a Hypertherm portable machine and this machine is almost the same but cheaper. Consumables are cheap and last surprisingly long. I recently cut 8 letters 24" tall out of 3/16 mild steel and have not had to replace any supplies. I gave 4/5 stars because there were a few little things that made it not ready to use (the welding helmet was a disaster and I just threw it away, the little slag brush was thermoplastic so I threw it away, the regulator water drain had to be taken apart and tinkered with sealant etc.) I used and abused the device I was given, cut off many hundreds of inches, and it worked flawlessly.
