Nearly all Magna oxyacetylene welding, brazing and soldering alloys require the use of a companion Magna Welding Flux.

Each Magna Flux is calibrated to provide optimum performance with the Magna Welding Alloy it was designed to be used with. The numbering system used makes it easy to know which Magna Flux to use with a specific Magna Alloy. All the Alloys in the Magna maintenance range that require a flux are of two digits (all Magna maintenance welding electrodes are 3 digits). The Flux is packaged in unbreakable plastic jars.

Some of the Magna Maintenance Alloys for torch application have the flux coated on the filler rod. In this case the letter 'F' is added to the two digits. Examples are Magna 33F and Magna 75F. However, extra flux is available in standard non-breakable plastic jars because on some applications extra flux is required. For example, when flowing an alloy through an exceptionally long lap joint, or when welding exceptionally dirty metal, extra flux is helpful.

Magna Fluxes are quite different from ordinary production type Fluxes. The purpose they serve is immensely important to the job at hand and they are not related to the ordinary borax, water and dye that make up a large percentage of what is currently being sold as - flux. They are the result of many years of scientific research.

Here are four good reasons for using Magna Fluxes:

(1) Magna Maintenance Engineered Fluxes have built-in 'Super Energy'. Every liquid (and molten weld-metal is no exception) has a force known as surface-tension. Surface tension is the result of the liquid making an effort to minimize its surface and to satisfy the requirements of the lowest state of energy.

Molten metal has a tendency to draw itself into the shape of a sphere, globule or droplet, and this shape (in welding terms) has the smallest surface of any geometric configuration - with an equal volume.

Substantial energy is required to change the geometric dimensions of the weld deposit. Especially so since it must be done instantly, because the molten weld-metal freezes very rapidly.

Through scientific research Magna Fluxes have been engineered to provide the super energy necessary to alter the geometric dimensions, break the surface tension and spread the molten weld-metal with incomparable force.

NOTE: When the weld metal has a high contact angle (as in the case of a sphere which often results with ordinary fluxes), very little strength is provided.

(2) Magna Fluxes have a powerful dissolving effect that promotes a point of total, thermodynamic equilibrium. This is achieved through special chemical reactions. This takes place deep within the metal surface. The process is one of actually penetrating into the metal pores and surface irregularities in order to prepare an area of tenacious anchorage.

(3) Magna Fluxes cleanse the base metal. Every welder knows that metal contains impurities deep inside the metal surface. The impurities are one of the main causes of poor bonding. Magna Fluxes actually penetrate the metal surface, follow the metal geography and perform powerful de-oxidizing and scavenging operations. Then, by depressing the melting point of these oxides, they are floated or vaporised, leaving behind a sterile, clean metal 'comb' into which the molten weld-metal will traverse and bond.

(4) Magna Fluxes contain micro-pulverized metals such as Barium, Magnesium, Strontium, Boron, Zinc, Tin, Molybdenum, Lithium, Chromium, Tellurium, Sodium and Misch-metal. Their super-micronized sizes give them the ability to become liquid and bond, with very little heat, ensuring that they form an affinity with the inner-pores of the metal surface. This affinity results in a surface alloying effect which results in an incredibly super-strong bond which is anchored 'inside' the metal surface.

All Magna Fluxes meet or exceed the United States Government quality control specification MIL-Q-9858A.
