AT A GLANCE INFO
Electrochemical weld and surface cleaning system
✔ Removes discoloration, oxide, and soot residue after TIG, MIG, and spot welding ✔ Ideal for angles, fillet welds, large stainless steel surfaces, and markings ✔ Alternative to conventional pickling pastes
GREENOX Macro – Weld and Surface Cleaner
GREENOX Macro is the environmentally friendly and safe alternative to conventional pickling pastes. With its patented electrochemical cleaning method, it reliably removes tarnish, oxide, and soot from stainless steel welds after TIG, MIG, and spot welding. At the same time, it promotes the formation of a passive chromium oxide layer that provides long-term protection against corrosion for the stainless steel.
Thanks to its automatic power control, the GREENOX Macro ensures fast, efficient, and even cleaning, even on delicate surfaces. The integrated touch panel allows for easy operation and adjustment of cleaning modes.
An optional marking kit allows for the marking and black etching of stainless steel parts – ideal for industrial marking.
The device features an integrated tank with a pump that ensures a continuous and automatic electrolyte supply. This enables fast, uninterrupted operation.
Effective cleaning & passivation – Removes tarnish, oxide & soot stains and protects against corrosion.
Automatic power control – Ensures consistent, material-friendly results.
Fast & safe application – Integrated pump enables uninterrupted work.
Versatile applications – Ideal for angles, fillet welds, large stainless steel surfaces and markings.
Environmentally friendly & safe – The perfect alternative to toxic pickling pastes.
