6. CLEANING AND POLISHING OF WELDS
Start of processing
6.1.
Before starting to pickle / polish a piece of stainless steel, check that all the preliminary operations described in chapter 5 have
been carried out correctly.
For its normal operation, the device requires the use of special electrolyte solutions.
It is very important to choose the most appropriate liquid for the type of processing to be carried out:
• SURFOX-T, an heavy-duty cleaning solution suitable for both pickling and polishing.
• SURFOX-G, a pH neutral cleaning solution suitable for pickling only.
Always refer to the product data sheet for detailed indications regarding its field of use.

Acid solutions are dangerous and can cause
damage to people and property: please read
carefully the chapter 1 on the safety regulations
and personal protective equipment that must
be used when working with these substances.
• Pour the electrolyte solution into the included jar or into a
plastic container large enough to hold the insert or brush.
• Fully immerse the insert with pad or brush in the container.
It is important to keep the electrodes always
well wet to prevent them from overheating.
• Turn on the device by turning the main switch (located on the rear panel of the unit) to the "I" position.
• Select the desired operating mode by pressing the MODE button on the control panel (see chapter 3.3 for more information).
• Press the button on the control panel to start the device.
Once started, the device switches off automatically after approximately 30 seconds of inactivity.
This is a precautionary measure to prevent the wand from being accidentally powered at the end of processing.
U
TILIZATION OF THE INDICATORS ON THE DISPLAY
During processing, bar indicators appear on the display showing in real time the voltage and current supplied by the device
(see chapter 3.1). When the workpiece is not being touched, no current passes through the wand and the voltage is maintained
at half the set voltage. The voltage only starts to rise gradually when work actually starts, thus minimizing the likelihood of
arcing or sparking at the point of contact between the brush/insert and the weld to be cleaned/polished.
