New 20lb CO2 tank is $160 which you can get filled. Gas company probably charges a $100 or so plus the gas for the same used tank.
A new 150 cu ft/580 valve tank is $240

I think you are better off buying the tank used on Facebook marketplace or Craigslist and taking it in for an exchange. I got my 20 lb tank for $20. I see them often for $50 around here.

The time before last, I got my 25 pound filled at Airgas for $3.50 They always wave the BullSh##t Hazmat fees too.. For normal people CO2 is way cheaper, and most commercial accounts too.(Overall)

 

[G-ManBart]

Well, I was just about to shout Bullsh*t

But, a commercial account might be part of the difference

Although that seems to be quite a big difference, but then again, I live in the constipation state.

Here is my receipt from January 16, 2023
For a 200 tank of 75/25
RENTAL TANK

My other tank is a 300 with straight argon
When the time comes, I will be bringing that to another company.
(I own the 300)

But yeah, that's definitely a screwup

Especially after I tried to block out that information

Part problem is the 120 v welder.
I have fluxcore since about 1980.
The only problem I had when try the 120 v welders they did not work with or without gas.
I gave up and purchased a 240 v welder and now welds great.

I'm a newb welder and have done a few small projects with a 120v flux core welder. My biggest frustrations so far are:

1. constantly having to wire brush the slag off the welds
2. blowing lots of holes in thinner material. Was welding some 0.06" thick tube, and it was a nightmare. Lots of holes, then lots of time filling the holes, and of course lots of wire brushing. I could do the wire brushing with a grinder, but then it's time putting on PPE, then taking off PPE, so it's faster to wire brush by hand.
3. this is minor, but having to step away after each weld to avoid breathing in the smoke. I could get a fan, but it's just another thing to set up.
4. not always being able to see the puddle. Sometimes this is because of all the sparks and smoke, and sometimes it's because I have to move very quickly on thin material to avoid blowing through. My understanding is it's easier to see the puddle when mig welding. Is that true?

I find 1 and 2 lead to projects taking a *lot* longer than I'd imagined they would. I'm tempted to switch over to MIG, but the cost of entry is kind of steep for my occasional DIY use. So I'm thinking maybe get a cheap chinesium mig welder like the 205-DS. And maybe another way to keep the cost down is to stick with C02 in an aluminum cylinder? For welding steel, is there a significant difference between all C02 vs C25?

Wouldn't a 240v flux core welder blow through thin steel as easily as a 120v?

 

[jrporter]

Amps are amps, melting wire is melting wire. A 240V welder will draw less amps from the house circuit than a 120, but if set correctly will be putting out the same amps to the wire.
I started out with a crappy HF flux core welder and for me it was just not adjustable enough to dial down for thinner metals. If you get a better welder you should get better heat control. I also would not get hung up on how much money you can save with 100% CO2 if you are just going to hobby weld. I have had my tank of 75-25 for a couple of years (or more) and still have gas in the tank. I also got away from flux core to have cleaner welds so going to a more inert mix was a simple choice.

Paid 59$ for a 336 argon exchange earlier this week. Used the old bosses account name

40$ for a 150 oxygen

And 51$ for a 75 acetylene.

 

[Broccoli1]

as mentioned keep searching Craig's List/Facebook Market place for CO2 jugs/tanks/cylinder

If / when you get a CO2 tank you'll need an adapter.

Hobart used to sell a kit that allowed you to run a paintball Co2 tank on a mig welder.

Totally awesome for portable work I would think. Obviously there was a reason they stopped selling it, either lack of demand or lack of intended function. I wish I would of snagged one though.

Must have been lack of demand. Jody at weldingtipsandtricks.com has done videos using one of those on his Hobart Handler. Worked great.

You could probably buy the fittings and make one yourself.
Just use a standard regulator instead of that fixed pressure regulator gadget
