I know those are inconsequential parts, but I don't want to mislead you into thinking that Americans are also making those parts, or that the machines are 100% American. I will, though, attest to the fact that Miller and Hobart operate plants in the USA employing American workers (legal ones, to boot), to make their products.
They even hand-wind the generators in their engine-driven machines, then the rotor balancing is done on a machine that must be 50+ years old. There is very little automation.
With many products, like boots or screwdrivers, I don't understand "American Assembled, Handcrafted" or whatever. With a complex product like a welder, with many inputs, it is more excusable.
However, back to your point, those silly parts are small peanuts. I've seen Chinese units blow a few boards in a row before the guy just buys an major brand unit. Even within warranty, for half the upfront price of a Miller, and with repairs done free.
For what it's worth, I even know a guy whose Hobart machine failed out of warranty. He called Hobart, and they agreed to cover 100% of the costs.
Even if Miller or Hobart had Chinese **** for sale, you'd at least know the company would be around for support after a few years. If Eastwood changes suppliers, who's going to be able to sell you parts?
