Tig cooler

[Richard.]

This is the one I got

Is 6amps enough??
What does the pump draw. You'll need a supply double the pump rate to be able to initially fire it up. They draw more current trying to pump water From start up.

It is the max I was recommended be caus the pump uses 3.5/5 amps I'll just put it inside then it's just the reviews said it got pretty hot

Might be ok.
I remember going through the ballache trying to get a 6 amp lap top transformer to start a 4 amp pump. It was having none of it because the pump was drawing to much current at the initial start up. Without water it would power up (just) but when it had to work a bit harder to spin up with water to pump it wasn't a gutsy enough supply to do it. Long story short I went for a 10amp step down transformer and it was plenty then to fire up every time. You might be lucky but you might need more power.

I will see if I have to get a different one I will I think I have found a way to earth it I will post pictures tomorrow's and see what you say

As Wallace said. If your pump is 12v and your fan(s) are 12v and you keep the 230v mains supply outside of the case then you don't need to worry about earthing it.
You would only earth it if there is a risk of mains voltage coming in contact with the cooler essentially making it live. The earth would then provide protection if you touched the live case.

I have put the 230-12vot adapter in the case now and put the earth cable to the power adapted and to a bolt on the case

Sounds good to me mate.
Are you powering 12v fans from it as well?

Yes

 

[Jlg]

This is how I have earthd it and what I have got done the first picture with the cable tie around the wire and bolt is how I have earthd it for now

@Richard. what is the best wp20 water cooled torch for around £100-150

 

[Richard.]

You'll get a ck20 for that. But if you start adding sheaths and switches with plugs/ specific water and gas fittings etc then the price rockets. If you just buy the torch off the shelf it will come in budget but it comes as standard with no sheath or switch and the gas/water/power lines are fitted with 3/8 bsp as standard. @Jim Davey is a good torch man I wouldn't look anywhere else now for mine personally. I've had a couple of the binzel SR torchs too and to be fair for the little cost they ain't half bad

 

[Jim Davey]

You can get a nice AbiTig Binzel torch for that kind of wedge.

Could you tell me how much one of them will cost

 

[Jim Davey]

I can, what length and what machine is it going on?

4mtr esab buddy tig

And this it it almost done jus need the radiator to come and tot get a pressure gauge would you recommend I put a thermometer on it

 

[Jlg]

@Jim Davey did you get a price for it

 

[angellonewolf]

cant you put a nut and bolt with washers on it to connect the earth it is connected but a good mechanical connection would be a lot better

I have just done that a minute ago I had second thoughts about it like that so got some nuts and a ring conector and bolted it on

Nope. I wouldn't use a pressure gage either. If your getting 1-2 lpm back into your tank then it's doing just fine. If the pressure is too low the water simply won't be coming out the other end. Too high and you'll either be getting too much flow or the hoses will be bulging. Keep it simple is the best policy. Iirc you can't set the pressure on those pumps so what benefits would a pressure gage offer
