I have used one quite often. I just used it with the settings on the machine and it worked pretty good. I didn’t use it for fabrication but for weld procedures.

Not on a cst280 but we have a miller welder that has those options. Seems like it is typically set to stiff which always reminds me of an old Miller transformer machine versus the soft which welds closer to our 600a linde or what I would typically associate with Lincoln machines.

We have the CST 280's at work for pipe welding with stick and tig welding. The machines are so nice that I bought one years ago. We can weld all day with 1/8'' 6010 and 3/32 low high on 6'' schedule 40 pipe. Setting the machine for 1/8'' 5P 6010, is pretty close to what is a great setting for 3/32'' low high. Each machine is a little different so you'll have to set to you're liking.
Our machines are on jobsites and not near to where we are doing the welding. Each welder has his preference for soft or stiff.
Each guy has a different setting for stiff and soft. We usually set the heat and stiff/soft setting welding by the machine. The stiff or soft doesn't change after that. So, it's on soft / stiff for the duration of the job unless another guy uses that machine.
You'll have to experiment to see what works best depending on what you are welding on.
The CST 280 is a great tig machine too.

I work on them at work pretty regularly. They are great welders. Most of the time I spend working on them is due to customer damage. We install them on our lifts that we rent to various companies. Most common broken part is the inductor. When the leads get yanked on it bends the plate the ports mount to and in breaks the end off of the inductor. Occasionally they'll have more damage than just that, but thats the most common. I've had them so far apart that one time I was handed one in two boxes and told to reassemble it and see what's wrong with it. Of course there had been numerous parts robbed off of it in the meantime. I did get it back together and working good again though. If you ever have problems feel free to reach out, as I have access to the factory service manuals for them!

I've never seen a tig setup with one. All of ours are used as stock welders. Of course they are used by Iron workers building structures and such. Tig would take far too long for them to use I would assume. Of course they do get paid by the hour! Haha
