To avoid wear-out of tips switch off un- used equipment, or reduce heat. Mix of lead-free solder alloy / parts with leaded solder alloy / parts is possible

16、but PHILIPS recommends strongly to avoidmixed solderalloy types (leadedand lead-free). Ifonecannot avoidordoes not knowwhetherproduct is lead-free, clean carefully the solder-joint from old solder alloy and re-solder with new solder alloy (SAC305).
