Welding gas advice wanted
sujit roy
I'm thinking of getting a AR/CO2 gas cylinder for my MIG welder to try and practice welding thin metal. I'm currently using flux-core wire to weld thick metal without gas. I called Madco Welding Supply now known as Linde Welding Gas & Equipment Center in MV and they gave me some options.
It seems the difference in price between a 40 cuft and a 50 cuft tank is about 17$. (188 compared to 205) The price to fill the 50cuft tank is 38$ compare to 31$ for the 40 cuft tank. I'm not going to be welding much, but who knows. In the scheme of things, the price difference between the tanks and gas is not much. What should I go for?
There's a place called welders heaven in Santa Clara. Are there other shops worth recommending?

ALWAYS REMEMBER TO TURN OFF YOUR GAS BOTTLE WHEN DONE WELDING
Probably go for the larger bottle unless portability is a consideration.
If going for a CO2 bottle know that there are 2 different styles: one has a straw that draws liquid off the bottom the other is designed for just gas. If you get the wrong bottle it will freeze up your regulator.
Have the gas supplier recommend the appropriate mix for the metal you will be welding. If you are planning on doing aluminum or stainless then you will need the more expensive mix but it typically works for mild steel. If just doing mild steel you can get away with straight CO2 but that won't work on exotic metals.
If doing aluminum you will probably need a spool gin to feed the wire.
A welding cart with a bottle rack is worth considering if you do not already have one.
Once you go with solid wire and gas you won't go back to dirty flux core. Don't throw away your wire though as one of these days you will need to do a quick weld and discover you left the valve open and the bottle is dry.
Get some old tupperware containers and keep your spools of wire in them with a couple of silica gel packets to prevent rusting and just keep them clean. You can also store the wire Tweco tips with the roll of wire to keep them handy. There are 3 common sizes and you want to use the right tip to fit the wire.
Happy metal burning.

I bought a Millermatic back about 15yrs ago with the cylinder as I was doing a lot of body work. Its a 110v unit and my cyl is about 2' tall. I could go a couple years before refilling it. I use Argon/Co2 mix. The last big project I built was a loading ramp for my Isetta trailer. My whole setup back then, welder and cyl, about $750. Purchased at welding shop on River St. Back in 1978 we bought oxy/acet set up in Santa Clara on Dela Cruz x Martin, I forget the name but has since sold.

I have always used straight CO2 on my old 120v Lincoln mig welder with generally satisfactory results. On my newer mig/tig 220v I use argon/Co2 mix for mig and pure argon on tig for alloy.
