Tig Cooler water temerature?

I did look into that..

But couldn't find one in 200mm size.
also, I'm using a digital temp display which runs on 12v.

happy with the fan... it's silent.

So the fan is just overkill/peace of mind.

I guess.

I would imagine it would take a lot to get 5 gallons of water to the boiling point.

Re: Tig Cooler water temerature?

Compare the stinger lead from your stick welder to the tiny braided line inside your cooler hose. It can be small because the heat is carried away by the water. If the water gets too hot it doesn't transfer enough heat.
Zap ran years cooling only with city water. I tried it after I had ordered the cooler, but it was back ordered. I feel that would be fine, but our water supply isn't what it used to be. In the 1990s the 200 home system was supplied by two natural springs. There was very little mineral or other contaminants. US Government forced a "new" system on us at a cost of 2.2 million 1996 dollars. Water is warmer now, and leaves a film in a glass you can't hardly scrub out with steel wool. I'd worry about plugging a torch.

Mine has a radiator but no fan because it doesn’t need it yet. I do have 230 amps available

Once the coolant in the line boils the machine could use a rest too...

Hasnt hurt anything so far

I'd say that's outside the norm though.

Re: Tig Cooler water temerature?

You should use the reinforced hose for the times it or another hose in the system gets pinched or stepped on and the temperature goes up for a minute or two. A filter in the system clogs, the pump does not put out because it froze and no longer maintains pressure or just wears out. I like the reinforced silicon hose myself, pricey for sure. Currently, I use the reinforced rubber hose it is a high-pressure hose for pneumatics like oxy-acetylene, which does get crunchy with time and needs to be replaced.

Sincerely,

William McCormick

Re: Tig Cooler water temerature?

Whether lines expand or not would neither affect the flow or pressure.

The lines expanding only happens once initially after that nothing is different.

A expanded line would flow MORE if anything.

It has larger I.D. Lol.

Procon makes pumps specifically for TIG welder‘s you can find them on the arczone site.
That said,
You can most definitely use a carbonator pump, but you will need to swap out the bypass spring.

If you don’t you will blow the hoses right off your tig torch.

I am using a carbonator pump on mine
I called procon and they sent me the proper spring free of charge.

Re: Tig Cooler water temerature?

When I built my cooler I found info the showed the flow rate, don't remember what it was. But something like how long it took to flow X water verse time. The ProCon pump has a by-pass for adjusting the flow.

My lines are the stock HTP lines.
braided 8.5mm lines.

less than 30PSI is not flexing those lines.

WHAT LINES?
The internal lines coming from the pump to the torch in/out? and the radiator in/out?????
If so, I call BS

I have the same cooler, those lines DO NOT flex.

If you are talking about the CK torch lines, Yes.. they will expand.
But it does not have an effect on overall flow.

: Nature of the beast.

Re: Tig Cooler water temerature?

I bought a 1984 Dialarc 250HF with cooler. One evening I was wet. Warm water was coming from somewhere! A couple drops at first, then more. It proved to be the torch plugged, the supply hose failed. It was old. I went after the torch with several cleaning methods, never had a problem again.

Run your tig on DC at over 200A continuously over 5 minutes and report back. It's not too "hot", but it does get very warm, so I guess it depends on the cooler and ones perception of what is "warm" and what is "hot".

Well yeah that was Like my original question..

Maybe I will buy one of those temperature sensors with the probe and mount it on this new refurbished re-constitutionalized revamped cooler.

It’s pretty cool to just glance at it and know that the water is flowing
Might be just as cool to glance over and see what the temperature is.

It couldn’t hurt and also a heads up to shut things down.

I just replaced 25’ torch lines.
Not cheap.

Especially when it’s beyond your control and it’s out of warranty to boot.

Re: Tig Cooler water temerature?

I would be very surprised if you ever had a tube failure associated with pressure or heat. I don't believe it takes more than a few pounds to push coolant through a torch. I also don't think coolant gets very hot.

Re: Tig Cooler water temerature?

If you were talking about a closed pressurized system, yes I understand about expanding lines etc. etc.

But for a TIG cooler, there is no pressurization of the line

It’s basically in and out.

You can have your exit hose dump out into the open air and your pump will still maintain the same pressure

Re: Tig Cooler water temerature?

I’ve got some braided reinforced line but it’s overkill
And frankly ridiculous for this application.
