USER MANUAL
If the electrode is not in contact with the surface to be treated (i.e. there is no current), the pump stops
working regardless of the operating mode selected; this prevents the electrolyte solution from being wasted
unnecessarily.
The only way to force the liquid out, even if there is no current ow, is to use the TIMED program or hold down
the STOP button on the wand switch.
• Press the START button on the wand switch (or alternatively the button on the control panel) to start the device. The
fume abatement system comes into operation.
Once started, the device switches o󰀨 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.
• Press and hold the STOP button on the wand switch to force pump activation and make sure that the pad or brush is
properly moistened with the electrolyte solution before starting processing.
UTILIZATION 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.
• Brushes (A) are suitable for hard-to-reach welds, while pads (B) are particularly suitable for large welds.
• Start cleaning/polishing by positioning the brush/pad on the stainless steel workpiece.
• Pass the brush/pad over the weld by applying light pressure and continue the process until each sign of oxidation is
completely removed. Sparks and foam may form at the contact point between the brush/pad and the weld during processing.
This is perfectly normal.
• If necessary, use the – and + buttons on the control panel to adjust the output voltage and to obtain better results (if you
change operating mode, the voltage returns to the default level preset by the manufacturer).
