  • What do you use to mix harris solar flux?

    I saw methanol is recommended for best results but I don't want to have that laying around my house knowing how dangerous it is if it gets on your skin. I have kids and don't want to take any chances.

    I saw a video with the guy from weld dot com and he used alcohol but didn't specify what alcohol.

    another post said to use Heet gasoline antifreeze????

    what does everyone else use to mix solar flux?

    Never used it, does the recommendation for methanol come from their website, or the container?

      Description: Welding Flux

      Solar Flux is a complex chemical compound in the form of a very fine powder. Solar Flux is mixed with alcohol (methanol/methyl alcohol preferred) and brushed on the weld joint. It is formulated to shield the back of the weld joint from oxygen, dissipate heat and unwanted oxides, and to clean the surface of the metal. It will aid in the flow of filler metal over base metal and form a protective barrier to prevent re-oxidation and heat scale.

      Type B for stainless steel, (except 309, 310), precipitation hardening steels, chrome-moly steels, other alloy steels with nickel content below 25%.
      Miller Dynasty 350, Dynasty 210 DX, Hypertherm 1000, Thermal Arc GTSW400, Airco Heliwelder II, oxy-fuel setup, metal cutting bandsaw, air compressor, drill press, large first aid kit, etc.

      Call me the "Clouseau" of welding !

        I've never used Solar Flux either,but Heet gas line antifreeze in the yellow bottle is Methyl Alcohol (methanol); the red bottle is Isopropyl Alcohol (same stuff as rubbing alcohol, but no water or other ingredients added). What is unknown is what else Heet may add to the yellow bottle, so it may or may not produce good welds.

          I’ve never considered methanol any more hazardous than gasoline.

            Yeah my thought too. I have plenty of chemicals I need to keep out of reach of children (and dogs).

              Ethanol would likely work just fine. Get a bottle of 190 proof Everclear.

                I forgot about HEET... Denatured alcohol is illegal here, and I was looking for some to thin shellac with. The auto parts store might be the answer.

                  Why is denatured alcohol illegal? Where do you live anyway? I might have to send you some. I keep it around to use in my backpacking alcohol stove. Works perfect for making a cup of coffee. It burns cleaner than isopropyl alcohol.

                    You have to ask? California, of course. VOC regulations.

                      Ah, I didn’t know you lived in the land where everything kills you instantly, commiefornia. At least your governor is being reasonable.....oh wait.....
