Can't go wrong with a Lincoln. I have had a Hobart for about 9 years now, and it works fine. My concern for you is that for only a little more, you can get a new Hobart. The welding carts at Harbor Freight are actually very nice (a friend has one). I would hesitate paying that much for a used one.
I just looked, and I see new Hobart 140s available for around $500 with free shipping.
I am taking it to Arc3 here in Lynchburg next week to swap or fill.
I have exactly that welder and it works really well for anything less than 1/4 inch, and thicker than that you have to get a little creative with the heat and wire speed.
425 looks like a fair average.
That's good to know, according to the chart it only does up to 14 gauge with gas lol
That's not true at all, as my brother and I both have welded 1/4 with this one easily. (with good burn in)
I have an extra 5 foot tall bottle also, so when the little one goes empty I just hook it up to the big bottle and refill it.
The big one refills the small one on the cart probably 20 times easy.
What mix gas do you run and what do you usually set it at on the welder when you are doing say 1/8th inch
I run 1/3 argon and 2/3 CO2 I think (been awhile and I would have to look at the bottle again to tell you for absolute sure)
Wire speed and heat vary a lot on conditions so I just play with it till it welds nice so I don't pay that much attention to what the knobs say.
For me the clue when I got it is when there is more of a hiss when running the bead than a splatter sound and the weld burns in and lays down.
Bacon on the stove mmmmm
