I tried to post a video of how the machine worked but for some reason it wouldn't post. I have been a welder/ fabricator for 20+ years and have use all the industrial plasma cutters. I've been wanting one for many years but couldn't pull the trigger on a $1500-$2000 plasma cutter that I'm only going to use a few times per year, so I rolled the dice and bought this machine. I'm glad I did. It's a slick little machine for the weekend hobby welder. You can't beat the value for the money. I know it's made in China, but it's actually a decent piece of machinery. The ground clamp (or work place clamp for those that have to be specific) is a bit on the chincey side, the cable could be a bigger gauge and maybe a few feet longer but that's really my only complaint. The gun is comfortable to use. The plasma cutter is a touch start but you really don't need to touch the tip to the material when the tip is new and clean. Just hold the tip an inch away from the material you are going to cut, depress and hold the trigger then slowly move the tip toward the material. Once the tip is about an eighth of an inch from the material the arc will strike and you can start cutting. This technique will help with the longevity of the consumables. Keep in mind once the tip gets dirty enough then it is required to touch the tip to the material lightly until you use up the tip and need to change it, then the process starts over again. This machine cuts through 3/16 like butter and does well with 1/4 also. I have not done 3/8 yet as its advertised to be able to cut up to 3/8. It will cut through 1/2 if you go very slow. It will leave a good amount of slag at the bottom of the cut on 1/2 inch but it will cut it if absolutely need be. The cart pictured used 3x3 3/16 tubing and the plasm cutter made fast work of cutting my tube since I don't own a band saw. This machine comes with everything needed to set it up except for an air chuck connection for an air compressor. Click on the pic of the back of the machine and zoom in on the spot where the air connection is and you'll see that I took the next size up hose barb (I believe it's a 3/8. The machine comes with 1/4 inch) I was able to force the 3/8 hose barb in, which helped make a good tight seal, then threaded a female to female connector on so I could thread on the air chuck which was a male style thread. Also, use lots of the provided Teflon tape to ensure you don't have air leaks. I don't know anything about the customer service as I have not had to contact them, and as for longevity, the remains to be seen. I'm hoping this lasts a long time. Taken car of it should. The cart it's on is a Harbor Freight $40 cart and I would also advise if you put this on a cart like this, strap it down somehow. I just strapped mine down with a ratchet strap. The machine is about the size of a lunch box and also very light weight so it would be very easy to accidentally knock it over. I hope this review helps.*EDIT* I added a couple pictures to show how it cuts. If you look close to the cut of the material in the pic where I'm holding the torch straight on you will see the cut looks to be angled about 45°. To get a straight 90° you have to tilt the torch forward as shown in the other picture.*UPDATE*. I LOVE this machine. I've been using it now for close to a year and a half and have had no issues with cuts. The only issue I have with this machine is the clear air tubing it comes with doesn't seal the best on the regulator even with a clamp on it, so the air leaks. So, after I'm done cutting for a few min I unhook the air from the machine. I will eventually get a different chunk of air line and replace that clear piece. I just more important things on my plate right now.
