Well my mig convserion kit for my crappy lincoln weld pak 100hd comes in tomorrow and the only other thing I need is a bottle and gas. I was thinking about going with a 5lb bottle seeing as i dont do a lot of welding at all. I also would like to know if 100% argon is a good choice to fill it with? I am just trying to practice and get better, not doing any serious work on anything of value haha.

 

you are dealing with a gas, not a liquid. (ex n20 or liquid c02)
so they will be rated at cubic feet.

i just cant remember what numbers they are.

i htink my 75 25 bottle was 60 c.f.
