I'm studying. I had to watch videos to learn to weld but this is a great machine. It's powerful; it looks small but can completely burn through the surface of the base metal. I didn't like the face shield; I couldn't see where I was pointing until the flame ignited. I also have to hold the guard with one hand and steer the machine with the other. The device is excellent, but before using the device, it is better to order a better face shield. There are no complaints about performance; I like to study with him.
