I suspect that Eastwood and a couple of the others now work pretty well too. For a long time it really lagged, the cheap junk simply didn't work as well and wasn't very reliable. The USA stuff was super dependable, had a long warranty and was priced decently while the junk was still priced quite high.
I wouldn't mind trying some cheap stick inverters, I aint gonna buy them up to test but the super low end Forney wasn't much good at 100$. I suspect the 225$ dvi 140 may. My Max S cost 800 8 yrs ago but it really works well and even though it was a pinch before they may have got the 6010 issue doctored up it doesn't matter.
However something at 20% the price is worth taking a look at and it brings it really in to entry level affordability.
I havnt been to welding web, I saw a UTube a while back and a test or 2 from guy knew what he was doing and it worked.
As I mention the Forney, it is a 3/32 6011 machine. Anything else trips the breaker. A good one like the max will output 1/3 more 100%.
Hrere is a test and I doubt I was very sharp. pic one, machine struggles to make 75 at best and tripped half way thru with a 1/8 6011, pic 2, 3/32 6011 and can weld with that but its too dam small and fussy but it finished the rod. Pic 3 is 3/32 7018 DC rod and 4 is AC. Both barely made 75 if that and tripped.
6013 is mild penetration but has near the same current demands as 7018 to run correctly. The machine that made these needed another 10A minimum, just didn't have it.
