I want to buy a used AC/DC stick welder for my shop. I particularly want
one that will burn 1/8" 7018 with a decent duty cycle. Like up to 250 or
300 amps. I want red or blue. I want something as reliable as an old
"torpedo" welding machine. Translation: Maybe old, inexpensive, and built
to last a long time. Intended use rate: sporadic.
Suggestions?

I never heard of anyone burning 1/8" 7018 at 300 amps. The maximum
that I went to was about 150-155. I am not an expert but I would
expect that your welding rod would melt at that amperage.
Old CC welders typically sell for not too much at liquidations, worth
taking a risk:

Thanks for the links.
I know the range on the rods, I just like to use a larger machine than a
machine that is running right at the top of its capacity.
When I used to dive, we used to use the underwater hollow copper alloy
cutting rods with 60 psi down the center of the rod, and we'd use them at
highest setting on the machine, usually a SA200.

My first suggestion is that you rethink your requirements, which are
conflicting. If you primarily want to run 1/8" 7018, you will never need 300
amps. Also, high duty cycle generally conflicts with cheap. You might find a
decent used DialArc 250 for under $400 - maybe.
I own five welders in a home shop. For stick welding I run a Miller Thunderbolt
AC/DC. If I had to weld up a bunch of 1" plate vee grooved (meaning, lay in bead
after bead as fast as you can) I'd pick up another buzzbox and use them in
tandem. Around here I see them used for around $100 a lot. I have never found a
clean used DialArc 250 for what I considered a good deal.
You could also go slightly outside your red/blue spec. Here, for example, is an
example of what may well be a rebadged Miller machine with an Airco brand:

Finally, for an inquiry such as yours, you should post your location. If you
live in the Australian outback, if I know of a welder for sale in e.g. West
Seattle, it won't do you much good.

Okay. I live in Las Vegas, and I need a good used machine for general shop
use. I have heard the DialArc name quite a few times before.
