Passivation systems

Why Is Passivation Important?
Stainless steel is naturally able to resist corrosion thanks to a passive chromium oxide layer that forms on
its surface. The formation of this protective layer is called passivation. Abrasion or excessive heat (caused
by welding) will destroy this protective layer and expose the metal to corrosion. In order to fully restore
the corrosion resistance to stainless steel, heat tint and other surface contaminants must be removed.
SURFOX is a safe, effective and fast electrochemical cleaning system. The SURFOX system combines
both the cleaning power of electrical current and the passivation properties of electrolyte cleaning solutions.
Passivation begins instantly after the SURFOX electro-chemical cleaning process is completed. It usually
takes between 24 to 48 hours for passivation to be stable and complete.

Surfox 304 – patented electrochemical cleaning system with a flowthrough system,
TM
which facilitates the cleaning of MIG, TIG and spot welds, without altering the surface
of the parent material.
► Exclusive quick-change brush system to easily interchange brushes

► New conductive brushes allow cleaning of larger and hard to reach areas
► AC mode for cleaning or marking and DC mode for polishing or etching

Surfox 205 – engineered to clean TIG and spot welds on stainless steel and
TM
aluminum and with the use of special marking kits (sold separately), it can also
FINISHING ► Built-in fume elimination system (requires a compressed air line)
mark stainless steel, aluminum and titanium surfaces.

Switchable output: AC Mode: cleaning & marking - DC Mode: polishing & etching

This is a durable production model designed for every day use

Surfox MINI – comes equipped with a variable power setting that ensures
TM
a perfect finish on even the most delicate surfaces.

► This unit utilizes refillable electrolyte cartridges instead of an integrated tank
to reduce the weight and increase portability
► Excellent for use on repairs, touch-ups and small jobs

► This newly redesigned unit can clean TIG or spot welds on stainless steel
and MIG, TIG or spot welds on aluminum
► It can also mark stainless steel, aluminum and titanium surfaces with the use of a SURFOX
marking kit
