I am expecting my LS 160 P soon and I am wondering what size argon tank I should be getting ( I am brand new to tig) I expect to be doing a LOT of practiceing so I imagine i will be using a fair amount of gas initially.
what size is a good compromize for capacity as well as reasonable to handle when getting it refilled or exchanged. ( am 66 and no longer as strong as i was ( which wasn't too strong to begin with)
Thanks, Joe

Joe,
I have an 80 CF tank as I recall. It is about 4 feet high and 8" in diameter. I am 61 and have no problems handling it.

the 80 is a good size I have one and it last a long time. I got mine on ebay from Indy it is brand new and free shipping. I paid 152.00 and my local airgas took it with no problems. mine is 37inch tall and 6.7 round. good luck with your new toy.

80 should be fine!! When i plan to tig im probably just gonna end up gettin a 40cf. (little cheaper)

Cheaper initially but your refills will eat the savings up. It is just about the same to fill the 80 as it is the 40.

I have a tank that stands 5 ft at about 12 in in dia. I thik that it is a 230 cfm tank. It cost $80.00 to fill and because I had it so long I had to pay for high pressure testing. I think that the tank is to big for hoby use.

get the largest you possibly can!

bamacpl,
I agree with you, my 80 runs out entirely too fast.

I think that the tank I described is the largest. That said, there are daw backs mainly it is HEAVY.

I looked at several different sizes of argon bottles. The 80 was just plain too big for my cart and shop (hobby). A 40# was OK, but the gas runs out fast and part of the filling cost seems to be just a plain old service charge for the fill. So 60# worked for me, although 60's aren't too common.

I am an garage welder and have not used a whole bottle at 60 yet, 1 months time.

I agree with Gadget. The 40 runs out pretty quickly, and at least here at my gas supplier, it only costs a little more to fill an 80. I made the mistake of buying a 40 for my MIG, and now I'm sorry.

I have the LS-200P and when I got a tank for it, I got a 155 CF. Aragon. I was Practicing on Alum. PL.. I used it up in 1 week, I thought something was wrong with it so when I took it in for refill I found out that if I used 25% Helium 75% Argon that I would have better luck with getting my heat up and would be able to conserve gas, and that is what I did, I also opted for the largest tank I could get, 336 CF. . And I have been working with it for a week now and still going.

Whoa Bob,
336cf? You must have a fork lift to haul it around.
Seriously though, if I had the space and method to haul it I would probably like that size myself. What are the filling charges for a tank that size.

I haven’t had to pay for a fill yet it was full when I got it I paid 320.00 for the tank though

Gadget,
In the chicago area it cost $75-$100 depending on the weldind supplyer. This is for a 320cf tank.

Here are the sizes and the weights of the cylinders that I had to chose from.

46 ..........46 cf ......7” ..............24” ............25 lbs
80 ..........92 cf ......7” ..............33” ............47 lbs
125 .......125 cf ......7” ..............43” ............61 lbs
150........155 cf ......7.5” ...........46” ............70 lbs

I have the 125.....seems to be a good size for me.

I agree with Herb. The small tank does run out pretty quickly, and here anyway, it only costs a little more to fill twice as big a bottle.

Keith,

That is a really good deal. We paid nearly $400 filled for a 150CF.

I was talking about refilling my tank, not buying a tank that is filled.

Oh I see. I for a second thought you got the deal of a lifetime.

I have a few different size tanks and I find the 80 cu ft tank is a nice size for a wheel around cart, any smaller and you're filling up too often. I have a 122 I use stationary, tied to the wall. Anything larger than 122 tends to become a lease tank, these are my owned tanks. Just filled both the 80 and 122 in Houston, 80 was roughly $20; the 122 was $24. The cost really is the handling not the gas. Whatever tank you buy from whoever make sure it does not say 'leased tank' on it! Both 100% argon by the way.

I just bought a used cylinder today. 125 cf brought to my house, full, for $200.
it seems a little easier to lift than I expected, and I think it's $40-$45 to fill (canadian dollars)


I wouldn't get anything below 80cf. unless it will be carried around all the time.

One thing I forgot to mention regarding how fast you are using up your tanks. Check your flow rates, some of the machines show only l/min (liters per minute) vs CFM. As a rough rule I use one half of the CFM suggestions or a little less if your are reading l/min. It's a common mistake to use too high a flow rate, I normally use 5 l/min or so which does a great shielding job inside. Too much gas actually makes the welding harder.

Correction/Update...regarding gas flow rates. I use a gauge that has liters/min (l/min) and run 5 on small cups/very close work to 10 l/min on larger cups. A lot of books/gauges are in CFH cu feet per hour (in error I typed CFM in an earlier note which is what compressors are normally rated in). Quoted ranges on CFH gauges are about double the l/min ranges. If ya do the math it's fairly close for starters then adjust per your work. didn't want to cause any more confusion on what's already confusing! metric stuff...
