Rated 5 out of 5 by from Mig gas tank I purchased for 2 reasons. One, you can't buy a tank larger than 80 cf from the local gas supplier. Two, if you run out of gas on the weekend the local gas supplier is closed.

Can this cylinder be used for straight argon?

Asked by: Geo tig
This does have the same valve as the argon, so it can be filled with either ARG or ARGMIX, since it is a brand new, never filled bottle.

Do these cylinder (Thoroughbred MIX4-B #4 Argon/CO2 Cylinder) have a DOT# stamp on them? And also is there a 150 cf (empty) model to purchase? It appears there is a big deal at welding store (refilling) with the issue of DOT # stamp requirement.
