TIG Water Cooler

[Richard.]

This is what I should of done.
Sold the pump and bought another et3009 and made it like this.
This was tested with 230 amps on the mls and water remained lovely and cool.

Thought you (us) cooler geeks would like some pics of the Binzel CR1000 inside, fan pushes air out through the rear (rad). Hope you don't mind the pics Richard, this unit also has a flow switch should your Tig/Mig have safety system for prevention of startup without coolant. (not that I'd forget to turn it on )

You don't get much for your cash but when you want it "now" its a quick fix, only regret I have is not getting it years ago.!

But what you get is quality, reliability and simplicity. The key to every good design brief!

That may be what they call cooler porn.

For anyone not needing a cooler very urgently, then keeping a look out on Ebay will turn something up before long. Often its possible to get a good quality cooler, which comes with a non working welder, for a fraction of the cost of the parts needed to build a comparable cooler.

Picked up a Tweco TC900 cooler with Hitachi GP2 Tig set (needed repair), for £100. Cooler new is £900, and the one I got worked perfectly. Not as compact as the tiny coolers on things like ESAB Caddy, but will cool a 300A set all day no problems, and all parts easily available.

That binzel cooler is very similar as the r-tech/stalhwerk/everlast ones...

Bit of a re design.
Changed everything around this morning and we have results.
1st off I did away with my copper tubing and ran through the rad only which was better but the water was still getting warmish.
Then I moved fan 1 to blow through the rad. Was better but the heat from the motor was still heating up things around it and I'm not seperating it from the cooler so fan 2 has been added right behind the lame fan on the motor. CRACKED IT. adding a powerfull fan no 2 and directing the air flow through the motor has made this cooler run ice cold.
I've also got it all sitting in the chassis so it's tidier.
Next time round Pulse pump and accumulator. Much easier to squeeze into a small space without huge rads and loads of cooling fans. This works really well now. Been maxing out the Rehm over last hour and the water return is stone cold.
Next task. Boxing it up but still keeping optimum air flow. Not today though. It's working spot on for now.

Blimey, good job, looks great!

Thanks art.
I'm happier with it now. It's performance is much better with that fan over the motor.

 

[Richard.]

Splash of black
It will do for now till I find time to box it.

 

[arthur]

Amazing what a lick of paint can do, looks even better.

 

[HughF]

Same pump as the murex/esab one I think... Looks nice Richard.

 

[Richard.]

The old murex ones perhaps. The newer caddy/transtig coolers use a tiny pulse pump.
Cheers hugh.

Thats looking good amazing what a coat of paint does.
If i get a chance this week i will get a torch on the beer cooler and post an update on the pump performance.
Any idea roughly how many LPM your set up is moving?

Hi Chris
I'm looking forward to seeing what you do with that beer cooler.
Mine is putting 1.1 lpm back in the tank.

 

[arthur]

What setup do you measure with Richard, I know pumps have Q max and H max, do you measure yours from the final return pipe into a jug? Or off the back of the pump, the Binzel I have is rated at 3.5bar 7lpm Q max. Q max being same height as the pump I guess. H max being how much it can move?

 

[Richard.]

I measured 550 ml into a jug in 30 seconds. I measured it at the furthest point before it goes back in the tank.
Ck recommend 0.9-2.0 lpm of water at 50psi so I'm on the money with it.

I just measured my Binzel out of interest and it puts back 1.1lpm to the tank, CK20.

We've either both got it very right or very wrong.

 

[arthur]

Haha Yeah, well like you mine was flat out at 180-200A a few days back and seemed ok :S
