Portable scrubber isin't working

[The duckman]

I have a 1x1 room that i'm using to get my welder gas sorted. I'm a moron and didn't anticipate a few key factors so i'm having to use a convoluted method while my welder is in dire need of go go juice. I pulled a scrubber into my tiny room somehow and i'm getting it to filter out some other gases like co2 so i can pull the straight gases that i need and nothing else (i'm going on the assumption that if there's a trace amount of not welder fuel my welder wont go) . Yeah little problem with that the scrubber doesn't work. I put a battery in it. I put the right filters in it i even raised the pressure of the room to see if it was that. Checked the lever on the side of it to make sure and checked that i didnt need to cram a gas tank into the scrubbers rear end (pretty certain there isint one for it) so i have no clue why it isint filtering out anything, everything seems to be fine but clearly i'm missing something

Eh f it. Might as well restart for the 3rd ♥♥♥♥♥♥♥ time because of this ♥♥♥♥ i still want to know why the scrubber wasn't working but these hours of work can just go to hell i guess. this game needs a section in the stationpedia about all the reasons why something isint working because the general consensus of this game for me so far is "it doesn't work!" "too bad start the whole game again you impotent monkey because it's never going to work"

and you have put in the water ? ;)

Yeah i wish water was the solution. Although drowning myself would be lovely considering i have to restart the game again because of this ♥♥♥♥

Bugs still happens and the devs are faster with developing new things and slow on to fix old things. The only devs i know who can handle this perfecly in early access are the devs of "factorio" and "satisfactory". ^^

Portable scrubber has never been reliable in my opinion. But don't be so quick to assume this isn't a user error. Portable scrubber gets full and must be emptied if you have not checked that. Also, screenshots help if you want some actual help with this.

Why not build an arc welder? It uses just a battery. I never get so far that the initial welder gas needs a replacement because of the electric version is finished long before.

Figured as much

Yeah the scrubber was empty flicked the lever about to check that it didn't come preloaded eith anything

Yeah i'm thinking that arc welder is my best bet getting welder fuel (though i think i might be able to do that now in my new save) just seems to be an incredible hassle. Which, it shouldn't. It makes me think if the porta scrubber doesn't work then how do i seperate gases from each other unless i set up the proper unit for it which in many cases seems a bit of an extreme length to go to

To separate gases you simply use a few filtration units and a few insulated pipes/tanks. It's easier than most people think, just monitor the first input pipes, they tend to blow up fast due to how filtration speed works. Then use a gas mixer for the fuel mix and be fine with it.

Then fill your welder with whatever you want and fine, preferable 67/33 H2/O2.

Yeah i figured it'd be the proper filtration units, i'll mark this as topic answer for the time being

portable scrubber will collect gases into internal storage by default and release them when the lever is pulled. When internal storage is full it will indicate error.

You can however wrench it to a portable tank mount and connect to a pipe network. Then it will put the collected gases into the pipes instead of internal storage.

Now for collecting welder gas portable scrubber is probably not the right device. You could do that with portable scrubbers but there are better alternatives. For the welder you would need the right mix ratio of hydrogen and oxygen (i think it was 2:1 if i remember it right, look it up on stationeers wiki). Any trace of other gases or wrong ratio won't work. That means you would need to separate oxygen and hydrogen in different tanks and then use a gas mixer to make properly mixed fuel for the welder.

To set up welder fuel, i suggest just setting up ice crusher + 2 filtration units + 2 tanks + mixer. Be careful though not to over-pressurize the fuel bottle when filling it or it may easily explode and kill you. You can use a back-pressure valve set to something like 4 MPa to avoid over-pressurization.

So to clarify that i'm understanding a-o-k i can put my oxites and volatiles into the ice crusher to get my gases and from there with the proper filtration units filter out what doesn't belong in the welder mix?

yea, thats correct.

You must not build a room for melting ice anymore, you can just throw it into a crusher. Crusher is also useful to melt white ice for water. It has a separate output for that.

But - you must separate H2 and O2 in different tanks (or pipes) and mix them afterwards in the correct ratio. Its 2:1 H2:O2. So its better not to filter out the unwanted gases, but instead filter just H2 and O2 into separate tanks and release the rest through active vent, or lead the rest mix into another network or collect in another tank for further separation.

So this is a minimum setup:

1. Build Crusher, connect it to power line.
2. build two Filtration units (Atmospherics Kit) behind the crusher and connect them to power line.
3. put O2 filters in one filtration unit and H2 filters into another.
4. connect crushers gas output with a pipe to input slots of each of the filtration units. Make sure that pipe is not too short, it will serve as temporal reservoir for rest gas.
5. connect waste gas output of each filtration unit back to the input pipe.
6. build pressure gauge and manual valve leading to passive vent on the input line. It will allow you to release rest gas and avoid overpressurizing the input line once you have pulled out what you need. Watch the pressure gauge when melting ice, pipes will burst at 60 MPa but you should not allow to rise it over 50 MPa.
7. build a gas mixer behind both filtration units and connect it to a power line.
8. connect both filtration units filtered outputs to both gas mixer input slots.
9. set up gas mixer for a ratio of 33% O2 and 67% H2.
10. build canister storage behind the gas mixer.
11. connect gas mixer output to canister storage.

Thats it.
Then you make sure that the manual valve is closed, throw in some oxite and volatiles into the crusher. The pressure in the line to the filters will raise and will contain mostly H2 and O2 along with some N2 and possible little amounts of other gases. Turn on both filters. They will pull H2 and O2 separately and collect them in the pipes that lead to the mixer. Then put a canister into the slot and turn on the mixer. When youre finished just shut down everything and vent the line containing rest gases.

With that minimum setup however you must be very carefully watching pressures in order not to overpressurize something. You don't want H2 and O2 pipes burst next to you :-).

The whole system could be further improved by adding some storage tanks for H2 and O2 in between and installing some pressure regulators that would automatically vent pipes before they burst and not allow to blow up the canister too. The rest gases could be further transported into another tank or to another filtration system instead of venting them.

Also you might consider going for Arc-Welder instead of gas welder. It requires only a battery and no gas. You can build it with the normal tools-printer. But you need a furnace to make some alloys for that. The starting gas welder lasts long enough to build everything you need until you can build an arc welder.

i THINK the welder pulls fuel directly from it's fuel tank at the perfect mix so if you fill it with a improper mixture or impurities it will just ignore them and let them sit in the fuel canister but still function properly while drawing the fuel mix it requires from the canister
