STAINLESS STEEL WELDING MADE EASIERX-RAY QUALITY WELDS FOR OVER 50 YEARS THE INTELLIGENT ALTERNATIVE TO BACKING GAS

DIRECTIONS in Using Solar Flux Place some SOLAR FLUX powder in a container.

Measuring flux

Add alcohol (methanol - methyl alcohol preferred for the best results.)
Adding methanol Where can I find Methanol??? Look in your local auto supply store

Mix to a consistency between 'thin and soupy' and 'thick cream,' whichever seems to work best for you. The consistency of the mixture, whether thick or thin, does not affect the operation of the SOLAR FLUX or the quality of the finished weld. Mix only what you are going to need for a few hours or, at most, a day's work.

Mixing flux

Let the mixture stand for a few minutes while a chemical reaction takes place
Make sure the metal is free of dirt and grease. Brush the mixture on the back of the joint. Use it sparingly, just enough to get
complete coverage. Try to stay within one quarter inch of either side of the joint. Applying flux
Allow a few minutes for the alcohol to evaporate.
Weld using the same procedure that you would use if you were using a gas purge. Welding
Good practice dictates that you ALWAYS run and test a sample coupon when changing anything in your procedure.

USE TIP: How to obtain methanol in small quantities

Methanol/methyl alcohol is readily available in auto parts and accessory departments and stores. It is sold as 'gas line anti-freeze' and is commonly packaged in 12 oz. plastic bottles. Some brands are 100% pure methanol and MAY BE USED for mixing with SOLAR FLUX. The labels on these brands will say something like, "contains methanol" or "contains methyl alcohol CAS. 67-56-1".

Other brands may contain one or more additional chemicals and CANNOT BE USED. Read the label carefully! If ANY chemical, other than methanol/methyl alcohol - CAS. 67-56-1, is mentioned, DO NOT USE IT.

Our research indicates that the following brands are 100% pure methanol and may be used to mix with SOLAR FLUX: 'HEET', 'ORIGINAL DRYGAS', 'MASTER', AND 'GOLD EAGLE'. Be aware that there may be other brands that are 100% pure methanol that have not come to our attention. Also, the four brands mentioned above could change their formulation without our knowledge. So ALWAYS READ THE LABEL.

RESIDUE

The thin glass-like residue is chemically inert after welding and adheres tenaciously to the base metal. While this residue is unattractive to the eye, it does not affect the quality of the weld and usually need not be removed. However, if removal is desired, it is easily accomplished with a stainless steel wheel, stainless steel brush or common pickling compounds. Our research indicates that 'Wonder Gel', manufactured by Bradford DeRustIt Company is excellent.

(Note: there are some pipe or tube welding applications where absolute purity and a polished inside surface are required. These include food or beverage lines where subsequent product refining will not take place, medical oxygen lines, computer chip manufacturng air lines, and high service temperature (above 1000°F) steam lines. In these situations we recommend purging instead of SOLAR FLUX so as to avoid a difficult chemical cleaning process.)
