How has the thermal arc line of welders held up? I'm really contemplating buying one of the 252i machines. My understanding is they are Chinese made. I've been told by tons and tons of people to stay away from Chinese made welding machines. I don't know if this is the exception to the rule. Or if the info it is not Chinese made. I'm a garage welder but I'm welding a lot! I've been practicing and doing a lot of small projects. I don't want something I'm gonna burn up real quick.
