Using the large wand to electrochemically clean, polish
and passivate
A) Selecting the proper wand and accessory
Tungsten
insert
B) Selecting the proper current type, AC or DC
and proper current level, STD or MAX
MAX
STD
AC for cleaning and passivating the weld.
DC for cleaning, passivating and polishing the weld.
STD is recommended when using the tungsten inserts and
pads, MAX is recommended when using the brush or the
large graphite insert.
WARNING! DC mode is used to polish the weld bead to
match the mirror finish of the parent material.
TIP! When using the polishing mode (DC), use plenty
of SURFOX electrolyte solution.
Note: When using DC setting, the SURFOX electrolyte
solution will become slightly yellow or will darken.

C) Selecting the proper pumping mode
Manual
mode
Manual pumping mode. Choose the manual pumping
mode to control the amount of solution pumping to the tip.
Hold the large wand ON button down to pump solution to
the tip. Release the ON button to stop the pumping cycle.
Always use enough solution to keep the cleaning pad wet.
Automatic pumping mode. To start the automatic
pumping mode, press the ON button on the wand. Once
it is activated, it will automatically pump the liquid. The
quantity of liquid can be selected from less to more.
D) Cleaning and passivating
To clean and passivate, press the large wand ON button.
Make sure the cleaning accessory is saturated with
SURFOX electrolyte cleaning solution before starting to
work. If the cleaning accessory is too dry, it will wear
prematurely. Start working when solution drips from the
cleaning pad.
Do not press hard, let the electrochemical process do the
work. Do not use the cleaning accessory like an abrasive
pad.
WARNING! When using the machine for the first time, there
could be water in the system from factory testing. Adjust
the liquid pump setting to automatic at maximum speed
and let the liquid drip into a disposal cup for 2 minutes
(amount of time required to empty the hose from the tank
to the wand). Then, adjust the liquid pump setting back to
desired pumping speed.
E) Neutralizing
1. Remove any excess of SURFOX electrolyte cleaning
solution using a soft clean cloth.
2. Spray SURFOX-N on the surface.
3. Wipe dry with another soft clean cloth to avoid cross
contamination.
Refer to neutralization procedure in neutralization section for
instructions on how to properly neutralize (page 15).
