    Add another tea bag. That one's done.

    Nothing to worry about. You've still got antifreeze protection.

      Just wandering what is causing that darking of the fluid, the levels full.

        What coolant did you use when you filled the coolmate?

        I've had mine almost 2 years, and the coolant has never changed color, with a similar amount of arc time...

            Use coolant specifically for tig coolers and add only distilled water.

              Did you flush the torch lines first?

                It's likely that he is not running a real LWS tig mix, and/or used tap water instead of distilled water.

                  No, 6 hours in the last 3 weeks.

                  And, the dynasty is not the only welder I own. I do more field welding off an engine drive than shop welding off of the dynasty.


                  And, even though I felt it was a rip-off, I went ahead and paid for the TIG-specific coolant from my local welding supplier. Seems like that's a better bet than gambling on automotive coolants...

                    6.5 Hours in 3 Weeks seems like a fair amout of use.

                    Yes it is the the coolant supplied with the new unit, Miller premixed coolant.

                    I did not notice the darker coloring until 5 hours or so. The torch and all parts are great, I really love the machine works Great.

                    Just tring to figure whats causing this. I will not run distilled water I am up in the high North only 90 frost free days a year.

                      Off hand, i would say that it is simply picking up particles from the torch, etc. Also, did you leave the cap off for a long time/ possible get dust in the coolant? Then maybe it could be mold of some kind?!?! just saying

                        any chance the radiator fins are plugged with fuzz?
                        allowing the coolant to over heat. If the coolant gets over 160F. The pump gets damaged. The veins in the pump swell and grind down putting carbon in the coolant. This can make it dark. One other reason for dark coolant. Is one of the rubber hoses breaking down and putting rubber into the coolant. Any chlorine in the coolant will cause rubber hoses to break down.

                          I would love to hear a tech chime in on this. I have the same issue with my Dynasty 200DX. I added the factory supplied fluid (I did not dilute it at all, per instruction). The fluid began turning yellow/orange on me within a day or two. The machine is brand new. I was only doing some very light torch work to begin with. I have not had any heat issues.

                          Out of concern I changed the fluid about a week ago. I did not flush the system so there was some immediate color change but the fluid is continuing to darken with use.

                          Oddly enough the container says "For use with TIG MIG PLASMA RESISTANCE INDUCTION" but it also states that it is not for use on a push/pull system... are they referring to AC? It has some comments about "may also be used in any system where aluminum is NOT in the coolant path." If I am welding aluminum it shouldn't have any affect here, right?

                            Mine Too

                            I bought a lightly used tig runner 200 DX and the guy told me it was ready for a coolant change. Unit was cared for and not abused and coolant was tan/brown upon pumping out. I did not flush the unit, so my new $25 a gallon factory coolant became tinged ASAP. Looks like some oxidation of whatever secret stuff is in the coolant.

                              I flushed mine with distilled water throughly yesterday. I did not like the look of that fluid, it seemed too viscus. I suspect someone at Miller choose the wrong supplier for their coolant and somebody will pay a hefty 'oopsy daisy fee' on this one. The fluid had some nasty material that I can only describe as pond scum that remained after the first flush. It took a more active cleansing of the reservoir tank to remove that stuff. Upon inspection of the metal filter, I found small remnants of this fleshy material. I ran over 5 gallons of distilled water thru the system before I felt confident that the majority of contaminants were removed. Keep in mind this unit is barely a month old.
