The newer liquid cooled machines are cheaper and foolproof but can only weld thin materials, the actual laser can be adjusted for how big of a circle the laser rotates at the weld; you just drag it across and a perfect stack of dimes appear
No because the cheap ones are Chinese and lasers can be very dangerous, watch some videos and see if a lot of thin material (even dissimilar materials) are in your fabricating future. I get by with a Hobart 180 tig for almost everything I do but would love to mess around (safely) with a Chinese laser
Nice, I recommend atleast a 125cf cylinder of argon. That's the size I have and if I weld a lot it'll be gone in a week.
You can lay down an argon cylinder, you shouldn't lay down an acetylene bottle. I can lay the 125cf bottle in the back seat of my wife's fiesta.
or a 
for me.
I have that tungsten grinder, it works decent. I'd like one like the sharpie brand, but over $400 is hard to swallow for a hobby extra.https://www.eastwood.com/eastwood-e...IBld_2wrlOPS8bUdJ1ZtLWoeCHvG5nNYaAjblEALw_wcB
I have this one on the way. The price seemed too good to pass up, and Eastwood is a well-known brand to me. By well-known I mean I've heard of them quite a bit. This will be the first of their products I've used, so I'll let everyone know if it's a
Probably has an air filter and catches all the dust. The weld shop where I work has a similar set up that has to be used for any of the radioactive tungstens like the red thoriated.
