1 Warning
Caution:
•Pb free solder has a higher melting point that standard solder; Typically the melting point is 50 - 70°F (30 -
40°C) higher. Please use a soldering iron with temperature control and adjust it to 750 ±20°F (400 ±
10°C). In case of using high temperature soldering iron, please be careful not to heat too long.
•Pb free solder will tend to splash when heated too high (about 1100°F / 600°C).
NOTE: Weight indication
Greater than or equal to 1kg : indicated by 0.05kg.
Less than 1kg : indicated by 0.01kg.
