First time build - Steel Frame CNC Router

[cropwell]

I don't know how much you intend to weld after your build, but I found using disposable bottles expensive, especially when the regulator leaks.
CO2 is not the best shield gas, Argon, Carbon Dioxide with a trace (2%) of Oxygen seems to give better results. I bought a Hobbyweld 15 cylinder with a decent regulator and I don't regret the money spent.

Weld spatter does not hurt - at first - so I echo the cover up. If you smell bacon when you are welding, you have spattered yersel. I don't wear socks and it ain't fun when it goes down the side of your shoe

Cheers,
