Using The Hand Wand To Electrochemically Clean, Polish And Passivate; Selecting The Proper Mode; Selecting The Proper Pumping Mode; Cleaning And Passivating - Walter SURFOX 204 Manuel De L'utilisateur

Using the hand wand to electrochemically clean, polish
and passivate
A) Selecting the proper mode
B) Selecting the proper current type, AC or DC
AC for cleaning and passivating the weld.
DC for cleaning, passivating and polishing the weld. The
cleaning and passivating process takes longer in DC mode
than AC mode and requires more electrolyte cleaning solu-
tion to prevent premature wear of the cleaning pads and
tips as well as preventing white haloes on the parent mate-
rial.
WARNING! DC mode is used to polish the weld bead to
match the mirror finish of the material.
TIP! When using the polishing mode (DC), use plenty
of SURFOX electrolyte solution.
Note: When using DC setting, the SURFOX electrolyte solu-
tion 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 hand 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 pump-
ing 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 hand wand ON button.
Make sure the cleaning pad is saturated with SURFOX
electrolyte cleaning solution before starting to work. If the
cleaning pad is too dry, it will wear prematurely. Start work-
ing when solution drips from the cleaning pad.
Do not press hard, let the electrochemical process do the
work. Do not use the cleaning pad 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 pump-
ing 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.
