Introduction
Congratulations on purchasing the finest electrochemical
weld cleaning and passivation equipment available today.
WALTER’s SURFOX
easily and cost effectively removes the heat tint from heat
affected zones on stainless steel and aluminum while
completely passivating the stainless steel surface.
SURFOX machines are equipped with self-regulating
inverter boards, automatically monitoring and adjusting
the current so as to ensure maximum cleaning effectiveness without loss of productivity.
Before starting, please read the SURFOX owner’s manual
completely as we take you step-by-step through the
start-up, operating and maintenance procedures of your
new SURFOX equipment. Your new SURFOX machine has
been built with extra durability to stand up to the heavy
demands of industrial use. However, like any piece of
electrical equip-ment, care and safety should always be
taken when using and maintaining this valuable investment.
With proper care and maintenance your SURFOX equipment will provide years of dependable service.

weld cleaning equipment quickly,
Operation
The SURFOX machine works by an electrochemical
process to clean and passivate welds on stainless steel.
SURFOX electrolyte solutions are phosphoric acid based,
approved for food industry, and are activated by an
electrical cur-rent to clean welds. The process takes only
a few seconds without damaging or scratching the surface
of the parts to be cleaned.
Your SURFOX machine can clean:
• TIG welds
• Plasma welds
• Laser welds
• Spot welds
• MIG welds (with Pulse technology)
Basics of passivation:
• The cleaning of the welds is not only for aesthetic
purposes but most importantly for passivation.
• Passivation is the treatment of stainless steel surfaces
to remove contaminants and promote the formation of
a thick and durable protective chromium oxyde layer.
• This passive layer will insure the corrosion resistance
of stainless steel.
• If passivation is not done properly, stainless steel and
heat affected zones may start to rust.

ELECTROCHEMICAL CLEANING: Select this setting
when using the mini wand attached to the SURFOX unit.
Select AC and 1, 2 or 3 depending on the amount of
heat tint to remove and the type of material that is
being cleaned.
ELECTROCHEMICAL POLISHING: This mode is
used for cleaning, passivating and polishing the weld.

Start-up procedure
Start-up procedure

A) Instructions
1. Place the unit on a flat stable surface, in a well
ventilated area where you will be working.
2. Connect ground cable to ground connector and attach
grounding clamp to work piece.
3. Connect power cable to power connector.
4. Mount the insert and cleaning pad or the brush.
SURFOX cleaning pads are made from highly heat
resistant polymers for extra long service life. The cleaning
pad must be replaced regularly.
Note: Never use the wand insert without a mounted
cleaning pad. If the pad must be replaced while working,
please observe the following:
• During the cleaning process, the wand tip and work
piece can reach very high temperatures.
Before replacing a worn cleaning pad or a brush, switch
the unit OFF and disconnect from power supply, allow
the wand tip to cool. The use of protective gloves is
recommended.
5. Screw on disposable SURFOX electrolyte solution
cartridge to wand. Press the top of the wand with your
finger to pump solution to the pad.
6. With switch in the OFF position, connect the unit to a
proper power supply as described under AMPERAGE.
7. Flip switch to the ON position.
8. Selecting the proper setting.
Select low or high depending on the amount of heat
tint to remove and the type of material that is being
cleaned. Brush option and large insert can also
be selected.
9. Make sure the cleaning pad or brush is saturated with
SURFOX electrolyte solution before starting to work.
If the cleaning pad or brush is too dry, it will wear
prematurely. Start working when solution drips from
the cleaning pad or brush.
Do not press hard, let the electrochemical process do
the work. The cleaning pad is a bridge between the
machine and the weld. Do not use the cleaning pad like
an abrasive pad and scrub. Doing this will shorten the
life of the pad.
10. When done, place wand in holder and switch unit off.

Neutralizing
The SURFOX-N liquid is a specially formulated cleaner
and neutralizer for the SURFOX electrolyte solutions. It is a
powerful ready-to-use formula which leaves no residue, is
non-toxic, solvent free, water-based and biodegradable.
Directions for cleaning and neutralizing
SURFOX electrolyte cleaning solutions:
1. Remove any excess SURFOX-T electrolyte solution
using a soft clean cloth. (This step is not required with
SURFOX-G)
2. Spray SURFOX-N on the surface.
3. Wipe dry with a SURFOX POWERCLOTH.
For more information about this product, refer to product
MSDS.
WARNING! When using SURFOX-T, be sure to wipe off all
excess from the surface and clean/neutralize to prevent salt
residues.
Insert cleaning pad
Press in wand tip
Clean the weld using the SURFOX machine and SURFOX
electrolyte solutions. Work only 2 feet at a time.
Note: the cleaning pad/brush should be kept moist –
not dripping.
1. After weld cleaning, use a clean cloth or paper towel
and wipe the affected area in a squeegee action from left
to right. Then discard the cloth or paper towel. (This step
is not required when using SURFOX-G)
After cleaning the weld with the SURFOX weld cleaning
machine, the electrolyte solution must be cleaned and
neutralized.
1. Spray the affected area with SURFOX-N cleaner and
neutralizer. Allow to sit for 15 seconds on the surface.
2. Use a SURFOX POWERCLOTH and wipe the affected
area in a squeegee action from left to right.
Note: failure to neutralize or neutralize properly the
SURFOX-T electrolyte solution will result in clouding, hazing
and dulling of the surface.

SURFOX Smart Passivation Tester
(54-T 011)
To monitor the state of
corrosion protection and
to ensure proper passivation of the workpiece.
Corrosion resistance of
stainless steel is significantly reduced near
welds as a result of the heating cycle. Visually,
this can be seen as a darkened zone next to the
weld. When electro-chemical cleaning is performed
on the weld, corrosion risk is reduced but the
treated zone still has to be passivated for 24-48
hours before the corrosion protection is fully
restored.
Stainless steel grade
Identification tester
No: 54-T 001
There are countless
types of stainless steels,
mainly grouped in 3
categories or grades:
200, 300 and 400.
Since it is visually impossible
to differentiate between
200, 304, 316 and 400 grade stainless steel, WALTER
provides a test kit that allows customers to instantly
identify the grade of stainless steel.

INPUT AMPERAGE: 120V, 50/60 Hz
OUTPUT AMPERAGE:
INPUT CURRENT: 4 Amps
OUTPUT CURRENT: MAX 15 Amps
10-30 V, AC/DC
Safety features
A) Sparks on the tip/work piece
To avoid short circuits (arcing), the machine automatically
stops when the insert touches the work piece (metal to
metal contact). There is an inverter board that monitors
the amperage every millisecond. If the amperage sharply
increases creating a short, the system will automatically cut
the power to the tip to avoid any damage to the equipment.
B) Internal temperature
To protect the internal components of the machine, there
are temperature sensors inside the machine. If the operating temperature is too high, the machine will shut down and
restart by itself when the temperature reaches an acceptable
level. There is an internal fan inside the machine to keep all
the components cool.
WARNING! The inside temperature can increase for
many reasons: high ambient temperature, lack of
proper air circulation around the machine, fluctuations
in amperage, electrical set-up in the shop, etc.
C) AC/DC current basics
Alternating Current (AC) flows one way, then the other way,
continually reversing direction. An AC amperage is continually
changing between positive (+) and negative (-).
Direct Current (DC) always flows in the same direction, but it
may increase and decrease. A DC amperage is always positive,
but may increase and decrease.
