That's like saying "go learn astrophysics." The topic is so deep, just googling random stuff isn't likely to get a novice on the right track nor do they know enough to know, what they don't know, to realize they picked the wrong rabbit hole.
That being said, if you aren't willing to nudge someone in the right direction, then silence is probably a more helpful than hollow and / or dismissive comments could ever be.
If you want to get a bottom barrel welder. I would wait for a deal on a cheap MIG welder. A stick welder is really only good for putting together pieces of thick steel. MIG will be more versatile and you can sometimes find cheap ones for not much more than this.

Anyone got any experience with this type of thing? Be great to have to fix things even if it's not professional, trying to see how well it works

The specs above state 39 amps as input current. How are people using this as home power outlets only supply 15-20 amps max? This would indicate that an electrician would have to install a special 6 awg wired outlet and a 50 amp breaker to even be able to plug the unit in?

The primary answer is that welders use transformers to utilize a lower voltage. Based on my understanding, outlets are rated at 15 amps at 120 volts (1800 watts), so if you reduce the voltage to say, 10, that would actually make the theoretical maximum amperage 180 (1800 watts).
Based on this consideration, the better/more accurate way to determine the maximum rating of outlets is to focus solely on the wattage.
With that said, if one of these welders happened to be tripping a breaker, I'd probably heavily consider finding the nearest trash can 🤣

If you get a 50 amp bridge rectifier and convert the output to DC , use smaller rods and have some experience it 's ok for very light duty work. I have a parkside welder that is similar that I bought from LIDL's for around $40.00 and it's OK for welding cracks on my mower deck and such. I do have experience welding though.

makes sense,....my first welder i got the harbor freight cheap $99 green mig and it's great for everything ...

The voltage is dropped to around 12v to increase current to 150amp. No need to change breaker
These are phenomenal little machines. I just welded 2 brackets onto a category 1 box blade for my tractor with a small unit just like this.
I also use these to revitalize batteries, doesn't work so well with car batteries but small batteries for my many lawn tractors. Not sure why it works better on them than auto batteries but it does.
They make attachments that insert heated metal brackets into plastic to essentially weld pieces of plastic back together.
These are great little machines that definitely have their limits but for most people they are priceless, they are small to store and they plug into a regular wall outlet and are very versatile.
I'm self-taught and absolutely no expert. I initially learned on a Harbor Freight / Chicago Electric MIG welder. A bad machine for a beginner to learn on. Lots of people recommend MIG for learning, and it is easier in some ways.
I switched to stick welding and that really unlocked things for me. Stick welding is a bit trickier initially, but once you learn some prep and setup steps, it becomes easier. I have a multi-process machine and will do some MIG for lighter metals, but I find stick to be easier now.
I'd suggest that this is a great deal for someone who wants to learn. Most of these inverter machines work pretty well. With the correct diameter rods, you can certainly learn and then get a lot of work done with a machine like this.
Tip: Spend more on the helmet than you do on this machine. Being able to see well while welding is critical, and a good, auto-dimming helmet makes all the difference in the world for a beginner.
Welding is an incredibly deep topic. Lots of awesome, online resources that can get you over the hump.

You don't set the voltage on a welder like this, you set the current. This thing probably is hovering around 24V output during welding. If you set 120A (stated max) @ 24V, that's about 2.9kW. At 75% (guess) efficiency, that's about 3.9kW at the wall, or 32A.
Given they say 39A input rating @ 120V, that's pretty close.
All of that to say: I could believe this would trip a 20A breaker if you're laying down long beads. short beads you could get away with if you give the breaker time to cool down. Given the 25% duty cycle on this, you'll probably be doing that anyway.
If you're not running 100% / 120A you might be fine. I wouldn't want to run this on an extension cable of any significant length though...
