1st one is garbage, dont even think of it.
Look at the duty cycles. The 120v one form P auto is only 20% duty cycle. AND its only at 105 amps. that means it will only run at the maximum (105 amps) for 2 out of every 10 mins. Again garbage. Thats not even enough to run a 7018 stick electrode on 1/8 plate. Too cold, and your going to be constantly pushing it to its limits, and going through them alot faster.
I take it your budget is around 200 bones? Save up till you have 4-500, then look at a used Miller/Hobart/Lincon. Something with around 40-60 duty cycle.
Although the Lincon is easily the best out of those. At 225 amps it would be more than enough to get proper penetration.
It does run on 220V power though, so make sure you have that before buying it lol

I dissagree, it takes more skill for stick to look good, but you can get just as good if not better welds with stick. And its cheaper because all you have to worry about are rods, not wire and gas + consumables like tips, gas nozzles ect.
