To assure best results, the parts to be treated should be thoroughly cleaned to remove dirt, oils, and grease with an appropriate cleaning solution prior to treatment with Weld Wizard 9350 solution.
All equipment, mixers, tanks and pumps should be clean and dry prior to mixing of Weld Wizard solution. Weld Wizard 9350 should be mixed with clean water (deionized or distilled water if desired) at a ratio of 1 part of Weld Wizard 9350 with 9 parts of water by volume to fill the tank or pipe system used so as to adequately cover all parts and surfaces to be treated. Polypropylene, stainless steel, or equivalents should be used for construction of all tanks and devices used in the Weld Wizard bath. Agitation of the solution in the tank is recommended to attain optimum results. Optimum results can be obtained with many parts by using Weld Wizard in an ultrasonic tank.
Heat the solution for optimum performance. Teflon coated (or equivalent), stainless steel or titanium heating devices are recommended. Your tests should indicate the best bath working temperature for the products you manufacture. 120-160 F is typical. Room temperature could be adequate depending on the end use.
Completely immerse the parts in the solution for a period sufficient to remove weld discolorations and other scale from the surface. This may be 15 to 30 minutes at room temperature, or as much as 45 minutes, depending on the severity of the discoloration.
If the discoloration is severe enough that the Weld Wizard 9350 only removes it partially, then other products such as Weld Wizard 9700 or Weld Wizard 9003 may be used instead to achieve the desired results.
Rinse the surface thoroughly with clean water and dry completely in air or proceed with other treatments (e.g., passivation) to obtain the desired results. Drying can be accelerated by use of a hot air blower (i.e. hair dryer), clean cloth, or other drying medium. Repeat process if needed to obtain desired results.
Notes on Use:
Although very safe in normal use, Weld Wizard 9350 is a Sulfonic Acid based material, and as such it may cause irritation to exposed surfaces of the body. See Material Safety Data Sheet before using this material.
Replenish the bath with Weld Wizard and water as appropriate to compensate for dragout, evaporation, and acid consumption. The pH of the Weld Wizard 9350 passivation bath should be held to within +0.1 of its initial value for normal operation.
Dispose of according to all federal, state and local regulations.
Weld Wizard 9350 should be stored at temperatures between 50°F and 90°F in 316 stainless steel or approved plastic containers (polyethylene or polypropylene).
