I just swap out the tanks on an as needed basis, so I haven't made a mental note, at least one that stuck with me.
Well, part of it stuck....

The amount of spatter I see in your photos above, and I'm no welder by any means, suggests you might play with increasing your shield gas pressure a few lbs at a time and see if that helps reduce the spatter. Maybe our friend Mikhail2400, above will have some advice?
I'm running 75/25, pressure is set properly, I think the splatter is mainly Operator issues. I try to keep the nozzle clean and clear, but I sometimes forget, and then trying to keep the proper distance is an ongoing challenge for me. I'm also realizing how important prep is, even though you can just weld through the mill scale, it doesn't really give you clean results.

I've gotten better, but still improving over time.

First test assembly of the base. I'm trying to set the length of the lift rod, still a bit long as the end sits at least an inch above the floor when at the lowest level. Can get some impressive lift out of it as well, however I will never need to lift it that high.

Small progress here and there...

I need to place some mounts for the support of the table extension. I want to weld some square tube to the base, that I can place a square tube inside of that will be the "legs". I really needed to mock up the assembly with the cabinet on the base, and the tops in place to locate where the tubes need to be. I'm using the top to another Unisaw as part of the table extension, as well as a Unisaw side wing. I want to locate to the mounting holes in the Unisaw top for a good, solid mount point.

First the Unisaw top for the extensions is threaded, so I needed to drill them out on the side I am bolting to the actual Unisaw top. I just went slightly oversize, not lining up perfect so I will re-drill when I pull it apart.

Second it seems that the wheels and rollers on the (used) pallet jack finally hit their useful life and have started dropping chunks of their "tires" all over the floor. I already purchased replacements but had anticipated I would get through to the final assembly before I used them, not the case.

Third, the lift assembly rod had to be put together in pieces, I expected the additional pivot points to cause some issue, and have been working on a fix, but something related that I didn't anticipate came up. When I have the complete assembly elevated, and I turn the lift/steer wheels sharp one direction or the other, it all tilts sharply towards the front due to the overhang/weight of the tops. I looked at the rollers on the floor when it is tilted, and they are both in full contact with the floor, so it tells me the lift rod is allowing this to happen. When it all comes apart, I will work on modifying the rod so this wonít happen.

Hey a cheap and easy fix for weld spatter comes out of a spray can. Sure you can play with pressure and heat or whatever knobs your specific welder comes with but you will still have some spatter. If your getting a good even consistent bead then your settings and travel speed are pretty much where they need to be. Even the pros use spray on anti-spatter as it really saves alot of time on cleanup. Been quite a while since I mig welded so dont recall the brand we used mostly but I have seen them on Amazon before. Plus any weld shop will carry some. Another thing you probably all ready know is to use nozzle dip. It will prolong tip life and prevent spatter from sticking to them.
As you have done figured out prep work is essential for welding. Mig-welding especially should be clean and free from rust or any other contaminant. The cleaner you get your work surfaces the better your weld will turn out and with less cleanup. I have to say that your welds arent bad at all.. Ive seen alot worse from guys who claimed to do it for a living.

I really love the way your saw is looking. The wrap was a freaking stroke of genius. It would have never crossed my mind to use it for a saw.

Edit; I wasnt trying to dismiss woodnthings comment about adjusting your gas pressure to help with the spatter. I dont recall the exact pressure range to be used for mig welding but increasing your gas flow a bit could help with the spatter. Its an easy thing to check.

Everything i build comes with a redneck warranty. If it breaks you get to keep both pieces.

More progress today, all of this is still mockup and build.

I got the material for the table support, put it in place and tacked it all in, will pull it and finish welding when I pull it apart. Also bolted the cabinet to the base.

I really like it.

I hope it's the photo. but the top looks like it's sloping downhill to the right, while the base is dead level across the bottom of the photo.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

It's the photo

All dead nuts on.

The factory Unisaw extension to the far right probably exacerbates the appearance because it is tapered.
