This product is an environmentally friendly welding material designed specifically for low-temperature welding environments. Its melting point is 139 ℃ (other low-temperature melting points can be customized as needed), which can achieve ideal welding results at lower temperatures and effectively reduce the impact of heat on sensitive components. This product meets and exceeds the relevant requirements of the EU RoHS directive, ensuring environmental friendliness and high performance.

Product features:

• Low melting point (melting point 139 ℃, other low-temperature melting points can be customized according to needs);

• Good fluidity;

• Less slag output;

• The solder joints are full and reliable.

This product is suitable for welding thermal sensitive components, thermal overload protectors, fire alarms, temperature control components, air conditioning safety protectors, etc.

instructions:

Suggest using our company's matching soldering flux for better performance.

After spraying flux on the welded parts, please preheat and dry them thoroughly.

Maintaining a full liquid level in the tin furnace can effectively reduce the generation of tin slag.

To prevent foreign objects from entering the tin solution, utensils that come into contact with the tin solution should avoid using materials such as zinc, aluminum, copper, etc.

Mixing different solder bars should be avoided.

The lead-free work environment should be completely isolated from the lead containing environment, avoiding the sharing of equipment to prevent pollution.
