Yes, the 2X40 is designed to clean all heat generated oxidation – whether it comes from grinding, cutting, or any other process that generates heat.

• Base Unit:
Our units are made with the end-user in mind. Each part is created using the highest quality parts available. The 2X40 allows for dual users and includes adjustable voltage controls.
• Wand and electrode unit:
Our wand unit was designed to give the user an increased level of comfort and longevity. The wand is constructed from a chemical resistant rubber with ergonomic comfort and the electrode of the wand is machined out of a solid piece of stainless steel– not a flattened piece of copper tubing. Our stainless steel electrodes are also completely replaceable. Because of the heating process, the stainless steel will slowly erode over time. Other units on the market require you to purchase a complete wand assembly replacement.

Yes, the starter package comes complete with the weld cleaner unit, (1) wand, (1) replaceable electrode, (3) 2X40 insulator sleeves, and (1) liter of cleaning solution. Additional cloth and cleaner can be purchased as needed.

No, it is actually quite the contrary. The process of removing the stains is a form of passivation, an electro-chemical procedure that actually restores the film and removes metal particles, dirt, and welding generated compounds. Cleaning the surface through passivation actually makes the product better able to withstand outside elements.

Passivation is defined as "the removal of exogenous iron or iron compounds from the surface of stainless steel by means of a chemical dissolution, most typically by a treatment with an acid solution that will remove the surface contamination, but will not significantly affect the stainless steel itself."

In lay terms, the passivation process removes "free iron" contamination left behind on the surface of the stainless steel from machining and fabricating. These contaminants are potential corrosion sites that result in premature corrosion and ultimately result in deterioration of the component if not removed. In addition, the passivation process facilitates the formation of a thin, transparent oxide film that protects the stainless steel from selective oxidation (corrosion).
