This is a very simple variable temperature 50W 110 VAC Soldering Iron. This is a great item for anyone looking for a little bit of mobility out of their soldering iron without loosing the ability to control the temperature. This soldering iron is incredibly easy to use, simply set the temperature on the control knob to your desired heat (350Â°C is recommended) and get soldering!
Lead-tin solder layers on copper leads can form copper-tin intermetallic layers; the solder alloy is then locally depleted of tin and form a lead-rich layer. The Sn-Cu intermetallics then can get exposed to oxidation, resulting in impaired solderability.he widespread use of this popular lead-free solder alloy family is based on the reduced melting point of the Sn-Ag-Cu ternary eutectic behavior (217 ËC), which is below the Sn-3.5Ag (wt.%) eutectic of 221 Â°C and the Sn-0.7Cu eutectic of 227 Â°C (recently revised by P. Snugovsky to Sn-0.9Cu).
