Once hooked up, it worked well, but setting it up was not clear for a new user. First, the unit comes with a 110V plug, yet it is sold as a 110/220VAC unit. The instruction manual gives no assistance as to how to convert it to 220VAC. There is no schematic or guidance or note to replace the plug with a 220V plug and it will work. There is no guidance as to a switch to change voltage. But, if you just cut off the 110V plug and replace it with a 220V plug, it does work. Also, on the website, there is no place to purchase replacement ceramic and copper consumables for the torch.
