Normally, I don't care much about country of origin, and have little to say about it. BUT, in the case of machinery, you can nearly always rework an import to get acceptable quality work off of it, if you are willing to spend the time cleaning and aligning, possibly upgrading bearings....thinks like that. With a cheap welding machine, there's not a lot you can do to make it substantially better, and therefore a better machine. I have to draw the line on most of the low level import welding machines. I believe a person would be far, far better off waiting and saving for a heavier, second hand machine from a reputable maker who can support you with advice and service when/if necessary, locally when possible.
Tanks aren't that expensive here. At least I don't believe so. I bought mine some time back and don't remember what I paid, but it sure wasn't $350 per, that I remember. There's a lot of welding business in East Texas, so maybe the volume is helping keep the prices down. There is also a lot of competition in the suppliers. That helps too.
