I didn't know whether to post this in tools or here but figured here would be an easier place to get an answer!

I'm going to be replacing some of my floor pan panels and am going to be renting a tank for my mig. I'm trying to make up a budget and want an estimate for the rental. The place has a pretty good deal where you just pay for the gas fill up. The tank they rent is a 125 cf. Will one fill up be good for what I want to do? Welding will include welding in two 18x18 inch panels plus the spot welding for the braces. Also, figure in some practice since I've never welded with gas (done lots of welding with flux core though). Should I figure on one fill-up, two or more?

Also, I might as well ask on this post, how do I transfer the tank? I don't wanna look like a moron and go pick it up unprepared! Should I just bring some tie-downs and strap it down up against the side of the bed or can it be transported in the cab?

Thanks in advance!

125cu ft Holy cow that is a lot of gas. I only have a 40cu ft and it lasts a while. Strap it down tight in the bed and be real careful. Shouldn't have a problem.

A 125 cu ft tank should be more than enough, even with doing some practicing.
The gas is inert, meaning it's not gonna blow up on you. I've packed mine in the cab with me before, but usually carry it in the back, tied down. Just a good idea to keep it out of that hot California sun.

however you haul it, strap it down good, even tho it's inert gas it's still under alot of pressure

Can be like a missile if something were to knock the head off

On my planet it's illegal to transport tanks inside a vehicle or transport without a cap. Sure I've put them in the back of the cab but the supplier cannot.

Make sure your in a controlled area(no wind) when using the gas. Windy days will blow the shielding gas away from the weld and it'll be a nightmare. I love my miller gas welder but actually borrowed my friends little flux core since i was putting my patch panels on outside. ALWAYS TRANSPORT WITH A CAP!!!

I will be in the garge when I do the welding. The only reason I've always used flux core is I was too cheap to buy a bottle:D

Never transport in the cab or trunk. Always with a cap and strapped down. There is over 2000 lbs. of pressure that can do a lot of damage if something happens.
