I have a older miller 625, 220v only. It cuts better than I can. I talked to a miller rep this week about their machines. ( he was doing demos of the new Miller 141 110v wire welders) Country of orgin and assembled are meaningless terms now days. Miller research and designs are mostly done here in the USA. Most of the parts are also built by miller in the US. Its the electronics that are sourced all over. Germany, Belgum, Swizterland, Japan, China, etc. Its the same with Lincoln, Esab and pretty much every one else. Lincoln does code their machines as far as assembly point. A U in the front of the Serial number designates USA. M= Mexico, I=Italy. Still those machines are only assembled in those countries. With the changes in consumer laws, any machine has to have something like 95% of its parts manufactured in the country of orgin in order to be considered a Built in USA. or Built in Mexico, etc. With the newer technologies, most of the electronics are not made in the USA, are usually bought in bulk, and then assembled somewhere else. Because these parts where not USA built and make up more than 5% of the components of the machine, the machine can not be labled Made in USA. Face the facts, even if you wished to build your own machine from scratch, you would have to buy parts not made in the USA and even though you did all the work in your basement, you still couldnt legally call it made in the USA.
