Frequently Asked Questions
About Bionil WF Fixture Cleaner
How often should fixtures be cleaned?
Depending on production intensity, weekly or fortnightly intervals are recommended. On robot welding lines, soot, smut and adhered spatter distort the fixture's reference points; regular WF cleaning preserves the dimensional repeatability of parts and OEE values.
What determines the dilution ratio (1:10 vs 1:20)?
For heavy soot and smut build-up, the 1:10 ratio (more concentrated) is preferred for a quick result. For light, daily routine maintenance the 1:20 ratio is sufficient and provides economical use. The operator can increase or decrease the concentration according to the condition of the surface.
Is air drying mandatory?
Yes. After WF application no moisture must remain on the fixture surface; otherwise the moisture evaporates during the welding process and causes porosity defects. All recesses and gaps must be dried with compressed air (0.2-1.0 bar).
Can it also be used on robot units?
Yes, it is specially formulated for robot welding fixtures and clamping apparatus. It is applied during the robot cell's offline (non-production) periods; the surface is coated with an air gun or manual spray, left to dwell and then dried.
