2, every1Kgor5 kgEncased in plastic boxes with certification labels; each3.0 KgPack into a carton and include the quality assurance document.

5. Precautions

1, strictly remove grease, oxides, and other contaminants from the brazing area and the surface of the filler metal before brazing.

2During brazing, a silver brazing flux must be used.

6. Storage in inventory

1The warehouse where the items are stored should have a dry and well-ventilated environment to prevent moisture; liquids such as water, acids, and alkalis—which are volatile and corrosive—should be strictly avoided, and it is even less appropriate for them to coexist in the same warehouse.
The solder should be placed on a wooden pallet; it must not be placed directly on the floor or against the wall.

2Be careful not to damage the packaging, especially the inner packaging, when accessing, handling, and transporting welding electrodes.English:Heat-shrinkable film”.
The silver welding wire packaging should be used up as soon as possible (within one week). Once the welding wire is exposed to air, its anti-rust duration will significantly decrease, especially in humid or corrosive environments.

3, in accordance withEnglish:First in, first out”Issue welding rods in accordance with the principles, and minimize the inventory time of products. Please store them by category and specification, and avoid using them incorrectly.
