POWERCOOL W400 (240V)

Notice:

Everlast is aware that customers may be using various  types of coolant in their PowerCool Water Coolers and with  our NOVA or other brand TIG torches. These range from distilled water to Isopropyl alcohol to  automotive type anti-freeze to R.V. anti-freeze to “private concoctions.”   Since the PowerCool product line  was released over 12 years ago we’ve gathered valuable data and gained experience concerning the use of coolants and their impact on both the lifespan of the cooler and the TIG torches themselves.  With that said, there are several areas of concern that we look for in a coolant. We have found that most popular alternatives fail to provide satisfactory performance.  We have taken our findings and concerns and listed them below as basic elementary requirements needed for best performance and product life.

Our concerns about TIG water cooler coolants are:

1. That the Coolant provide satisfactory Ant-Freeze Characteristics.  While some may provide some sub-freezing  characteristic protection, they do not provide enough or provide inconsistent  sub-freezing protection.

2. That the Coolant itself offer additional wetting and heat transfer characteristics, or at least doesn’t interfere with the water base level cooling ability. Not all anti-freezes are designed to improve cooling characteristics.

3. That Coolant provides anti-algae conditioners. This helps to prevent torch plugging and blockage of lines, and narrow torch passages and reduces the need for frequent coolant exchanges and cleaning of torches.

4. The shelf life of the Coolant is satisfactory.  Coolant should last in a commercial environment without break-down, gassing off etc. for an extended period of time.

5. That the Coolant is designed to be flowable for rapid recycle  conditions.  Some times of Coolant are for static  or low flow conditions only.  I.E. certain types of R. V. Coolant.

6. That the Coolant not be conductive.  Many automotive type coolants have certain conditioners and additives that make it electrically conductive.  Conductive Coolants can make High Frequency starting more difficult as it tends to rob and dissipate the H.F. energy. Can also contribute to arc instability in general.

7. That the Coolant be compatible with the common silicone, rubber, PVC formulations of the components found in our torch cables and most other brand torch cables  on the market without deteriorating them.  This is a large concern.  Certain types of coolant can cause dry rot, premature aging, and leaks. Good coolants also provide conditioners expressly made for protection and conditioning of the components.

8. That the Coolant be compatible with the materials found in the torch head such as brass, copper and solder without corroding the components. Good coolants also provide lubricity to the mechanical components without impeding flow or making it overly viscous.

9. That the Coolant be compatible with all the materials found in the cooler, including copper, brass, PVC, silicone, rubber, etc., without leading to corrosion, deterioration or component failure.

10. That the used Coolant be relatively safe, and not a severe hazard to the environment, or at least has safe disposal guidelines attached to it that can help prevent environmental damage.

It is for these reasons, that Everlast is now recommending that customers ONLY use commercial brand coolants designed for use with TIG welders with a rating for use with High Frequency (H.F.).  These coolants will usually include statements or information regarding the concerns listed above.
