Will 30 liters of LN2 be enough?
 

I have a welding supply store only 15 miles away so getting more will be easy. The guy said $45 for the 30 liters and $75 a year rental or $8.xx a month. $18 for delivery, but I'll just go get it.

How quickly can a freak like me use up 30 liters of LN2?

Now I must either make a "POT", or maybe buy one. My uncle can make anything out of metal.

How much is a good "POT"?

30 LN2 is a good 8-12 hours on a CPU pot I think depending on chip used. Hotter the chip the less time it will last.

30L lasted me 2 sessions 3 days apart. (2nd was short though... only about 2 hours)

I am a noob though...

Wow that's pretty shitty.

The 180 liter is $1.50 a day rental and it weighs 700 pounds, but would look nice sitting in the garage. The 180 would probably last me a month.

That would be ~$200 a month if I can make it last.

180 really wouldn't be too much LN2 at all. :ohcrap:

A good pot will run you about $200

Used pots can be had for nearly half that. There's a good used F1 EE at XS for $125 right now

32L only lasted 4 hours on Gulftown my first time.

You are on AMD so should not have to torch your pot and waste a lot of LN2. Also dont let your transfer cup stay empty too long, the more it warms up the more you lose to evaporation when you refill it.

I do imagine a 6GHz Thuban would be pushing towards the 6 hour time frame though LOL

Once I have a steady stream of HW I am going to rent a 160L.... costs me $150 a month I think...? (came to 80 cents a liter plus $45 rental and $18 hazmat/delivery charge)

My 30L cost me $70 bucks to go get filled :(

Thanks for the info Gunslinger.

He told me .92 per liter for 180 liters...all other charges the same. Sounds like I could really go through some LN2. I need to get the bulk tank the welding supply guy has......lol:D

EDIT: or marry his daughter.

Less than $29.00 here to fill my 32l....I would shop around.

I'm sure I could get it cheaper if I wanted to drive ~45 miles one way to get it. Have to look around some and weigh the options.

Might be a good idea.

When you called was that OTC pricing or with an account?

I don't have an account there yet.

Check Airgas and places like this! My dood fills my 30L for $20.

Things they don't tell you is they lose more than they sell. ;)

I'll have to check the Binghamton and Utica areas.

EDIT: maybe I should go in and talk to him about that.

In my case once the guys got to know me the price dropped some. :good:

(Let them know what you are doing with it and it will intrigue them)

THIS is the advice of the day! Once they know that you dont use it commercially and pure for fun they will drop the price.

Dude check with CryoWeld in Poughkeepsie, NY. (845) 473-3357 Thats where i get mine. 230L Dewar deliveered for $209. Plus a $66.00 mo rental fee. Don't mess with Airgas. Total crap Dewars from my experience.

Edit: IDK if they deliver to your area but its def worth a try.

Thanks for the tip...I think that is too far away though. I found a place called Haun welding supply.....they said they'd match the $1.50 a day rental(down from the usual $2) and they have 165 liter tanks which cost $70 to fill. And they deliver on Tuesdays. That's only $115 ohh plus the delivery...shit :thumbsup:

Airgas wants $125 just to fill a 180.

Plus Rental, plus Hazmat fees, Plus when you get your monthly rental statement there is another hazmat fee. They don't tell you that but its the truth. They freakin robbed my ass.

These threads always make me want to move........

I can't believe the hoops I've had to jump through and the sweet talking I've done still gets me expensive LN2.

YEAH bro... if you are a n00b then what am i?
a new born?

yep
i went to nashville welding comp. they filled my 30 for only $17:D
