Will 30 liters of LN2 be enough?

ny_driver · #1 09-08-2010

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.

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

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.
