Processing instructions
Preparation

• If necessary, clean the joints and the surfaces to be joined. Round off any sharp edges. Degrease the parts with a suitable solvent.

• Apply GreenFlux 18 M to the surfaces with a brush. The flux facilitates the wetting of the filler metal on the base metal. It can also be used as an indicator for the joining temperature.

• Heat locally to the melting point of the flux. Melt the end of the flux-coated filler metal rod and apply to the joint. Allow the drops to bond to the base metal. Spread the drops with a continuous movement of the flame.

• Do not overheat. 

Cleaning

• Rinse with water

• If cleaning is necessary, use a mechanical cleaning method: Sanding, grinding, scraping, etc.
