Equipment is a little difficult to use but once you get the hang of things isnt too bad. I was wearing welding gloves as I was also doing some welding at the same time I was using this machine. As the tiny keys heat up to weld themselves to the metal I would recommend wearing something similar to protect your hands and fingers. It will make use even mire difficult but trust me you will want some type of thick gloves to use this. I would like for the equipment to weld a bit better to the metal but it is specifically designed not to for a reason. The equipment did work as it was described and I have no major issues with it even though it did show up with a good size dent in the side of it. Did not effect operation so I did not report the damage. I am happy with my purchase and I would recommend this equipment to anyone needing to repair metal with dents.
