Carbonator questions (TIG torch cooler)

I finally received a carbonator pump. As a nice extra, included was a
water/co2 charging tank, for which I have no use but will keep on the
platform anyway.

Two questions

1. Do I need a pressure relief valve, and if so, what kind. The water
flows out of the torch return line quite briskly.

2. There is a control box mounted on the pump, with a relay and
integrated circuits and a signal transformer. It turns off the pump
after about a minute. If I power the pump off and power it on, it
restarts for another minute. It is trivial vor me to fully bypass this
control thingy, but would I be exposing this pump to any dangers?
(unlikely).

Later on, I would simply mount a 24V relay inside this box, to be
controlled by the welder.

look..... I am not trying to be rude, but we told you this just the
other day, why are you keep askin'

I told you to use a "T fitting if you think the pressure is too much,
you don't need to complicate things,
remeber !!! keep it simple.
if you are concern, install an inline water pressure gauge .
better yet buy a 50 PSI pressure regulator RV valve wich will keep the
pressure at 50 PSI all the time.

first, junk the electronics that limit running time to 1 minute ,
hook the pump to switch and to 110V

connect the water lines , fire up your pump / motor and see how far
the pump will **** the water stream without the torch being connected.
This will give you an idea about volume of water getting pumped.

like I said I ue d a "T" fitting out of the output side of the pump ,
one side of the "T" goes to the torch the other side returns the
access water to the bucket.
you can use a simple small 1/4 inch ball valve to control volume and
pressure.

you don't need much volume. nor pressure.

in my cooler it seems that 1/2 of the water gets dumped back into the
bucket and the other half of what ever the pump supplys goes through
the torch.

any time I stop welding and touch the torch head with my hand the
succer is cool to the touch. the cup is hot as hell.
that is all I need to know.

I really don't care what pressure is in the hose.
Never busted a torch hose yet.

I did weld without water (forgot to turn it on ) and still don't have
a melted hose yet.

keep it simple.
don't over complicate the darn thing.

you should be welding instead of dicking around with that cooler

Carbonator questions (TIG torch cooler)
 

ok, the subject is pretty much covered, and beaten to death. :)

one more final word,
just this morning I examend the water flow coming out of the torch
return hose.

as a reference: it appears the flow/volume is about same as I get out
of my fridge water dispenser. may be slightly more.
keep in mind this is not the full flow of the carbonator pump because
it is "T" off (as mentioned earlier.)
if you think about the small passages that are in the torch head , it
is plentyfull water.

good luck
