• 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).
• The DW brush (A) is suitable for hard-to-reach welds, while the 100 mm or 45 mm pad (B) is particularly suitable for large
welds.
• The polishing process requires a greater
amount of electrolyte solution than pickling.
• Always keep the brush/pad well moistened
with the electrolyte solution to avoid
overheating and a consequent significant
reduction in its working life; if there
are obvious signs of wear, replace the
component immediately.
• If the voltage is increased during processing,
the electrolyte solution evaporates more
quickly; make sure that the brush or pad is
always wet.
• Never use an insert without its matching
pad; the insert must never be placed in
direct contact with the steel workpiece.
• When carrying out cleaning/polishing, keep
the brush perpendicular to the weld and
never press the carbon bristles excessively
against the surface to be treated (C).
• For best results, periodically adjust the PTFE
sleeve of the brush to leave approximately
5/8" (15 mm) of carbon fiber is exposed.
