Guessing- fill the tank with inert non flam. gas and under slight pressure hes going to weld away. No oxygen, No Boom. Just make sure its purged of air. High school auto 101

Dah, Maybe I should backtrack posts once and awhile. This method was mentioned prior. Next.

It's okay - we've all done that... Me, probably more than a few times!

The real debate is all about Todd just wanting me to suck it up and weld away - skip all that cleaning and back gas bs.... Says the eyebrows will grow back in no time.

I was thinking that I have a few squibs laying around here somewhere... since I'm a pyro (retired) and I could take Coolwelders advice and just light 'er up... and once the smoke clears (and the fire department gives me the all clear) - I can weld on it, no problem -- all the gas and fumes should be gone.

I've been talking to Gwen about it though - and she's warming up to do the job this weekend - you know - while I'm away....

Thought I'd better make an into to what a squib is... sorry -- pyro lingo...

Squib (explosive):

A squib is a miniature explosive device used in a wide range of industries, from special effects to military applications. They resemble tiny sticks of dynamite, both in appearance and construction, although with considerably less explosive power. Squibs can be used to generate mechanical force, as well as to provide pyrotechnic effects for both film and live theatrics. Squibs can be used for shattering or propelling a variety of materials.[1]
A squib generally consists of a small tube filled with an explosive substance, with a detonator running through the length of its core, similar to a stick of dynamite. Also similar to dynamite, the detonator can be a slow-burning fuse, or as is more common today, a wire connected to a remote electronic trigger.[2] Squibs range in size, anywhere from 2 to 15 millimeters in diameter.[1]
Squibs are sometimes confused with electric matches, as well as with detonators. While those are specifically used to trigger larger explosions, squibs are generally (but not always) the main explosive element.[1]

Yes the "welding gases" are inert, but they mix. Like 75 argon 25 co2. How do you get both gases out the end of your mig gun? They mix. The problem with the gas tank is you do not know how much Argon it will take to be 100% none flammable. Dryice is the heavest of the inert gases and there is 100 times more gas in dryice vs a bottle of argon. So drop a bunch of peices in let it gases off. Don't guess with "welding gases"

Dry ice it is....

It's cheap - simple and watching the fog it makes will be kool...

I'm kind of planning on using this to clear out any remaining fumes or excess gas. My plan is to do this in Todds front yard... it should be 'ok'...

after your done welding the tank and your eybrows grow back. take the some of the dry ice and fill a 20 oz bottle about 1/2 full of water then take a small hand full of ice chunks and put the in the bottle and twist the cap on tight make shure you are outside and you can toss the bottle away from you and wait you will be amazed at how much power it has.and how loud it is

just don't bring you wife out to see it she won't be quite as impressed when the cap wizzes by her head trust me on this one. lol.

Eric -- I'm certain on the "wife" part!

Real men though -- play with bigger toys than that!

Here's a 50" inch shell being built at a munitions factory in Inchon, Korea... I am not "Mister Chin" in the photo... I'm the "other guy"... :>)

Thats one heck of a shell there. Todd could fit inside of that.
