HF uses insanely high voltages. Megaohm resistances can drain off significant amounts of your HF power. Think about the resistance of spark plug wires here. I don't know how that would affect HF though. I personally use an air cooled torch. Originally Posted by rlitman. Automotive antifreeze, has a finite lifetime. Re: Coolant for TIG welding For everybody who read too damn many fool posts on leaking hi freq; The machine was built to be hooked to a public water supply and still provide a sufficient amount of hi freq to establish an arc.
Now where in hell is the electric service to your shop grounded to? That's right folks, the public water supply, the world's largest ground network. Hi freq on a torch is ar RF frequency, and you loose a lot more by laying the cable across a concrete floor. Then there are quarter wavelength losses, and inductive losses from coiled leads. Are you under the impression TIG was invented in ? We been running this process since the 60s, long before ITW bought Miller and Hobart Bros and whored both product lines out.
Green antifreeze worked in and it still works today. Sodium silicate is a suspended solid in antifreeze, let it set a few years and look at the bottle. Then again, what the hell do I know after 50 years of welding? Re: Coolant for TIG welding This is another one of those it doesn't matter what anybody has done for the last 50 years without problems cases. It doesn't matter what you do, chances are you will not have a problem.
In my lil episode, tonite turned out fine, but I was worried when I found the cap frozen. And its been below freezing here for two weeks and my cooler has been idle the whole time. No problems yet Re: Coolant for TIG welding Not trying to start a flame war here, especially since Old Fart generally gives good advice and seems to know what he's talking about.
The problem is that simply recommending that a user just use "automotive antifreeze" or the "green stuff" leaves too many options. Some of the automotive antifreeze solutions use anti-leak addititives which can cause blockage problems in the small passages in the water cooled torch.
One I'm not willing to risk for the few dollar difference between auto anti freeze and the recommended solution.
To quote from page 4 of the Owner's Manual from the Miller Coolmate 3: "Use of any coolant other than those listed in the table voids the warranty on any parts that come in contact with the coolant pump, radiator, etc.
For something I change about every 3 years, I'm not willing to take the chance to save that little. You own the cooler, you own the welder, you own the torch. Use whatever freaking coolant your heart desires. Re: Coolant for TIG welding 30 years!!!!!!!!!!!!! Yes 30 years 2 Tig machines 2 coolers Green Prestone and distilled water.
