STORAGE and USE

Store in normal conditions at room temperature.

Avoid excessive inhalation of fumes. These are irritating to throat and respiratory organs. Prolonged or repeated exposure may rarely result in sensitisation leading to occupational asthma. Suitable fume extraction equipment should be used to extract flux fumes away from operators. (This important issue is also catered for, please contact sales for information and prices etc..)

Lead is harmful if absorbed into the body through the digestive system or skin. Eating, drinking and smoking should not be permitted in the working area. Hands should be washed with soap and warm water after handling solder, especially before eating.

The tip of the soldering iron should be properly tinned and this may be achieved with  402 solder wire. However, this does depend on the initial condition of the tip. If it is in poor condition, it may be more effective to pre-tin the tip with Tip Cleaner. Used correctly, this cleaner will leave the iron tip well tinned and free from any harmful residues which might be transferred to the work piece. For additional details contact  Sales. 

For best results use an iron tip temperature between 340 - 420 °C.
