Heat Gun For Soldering Of Copper Pipes & SMD IC.

Hot air is suitable for soft soldering. First, you clean and degrease the point you want to solder and heat it at full power (650 deg celsius). This takes between 50 and 120 seconds depending on material, thickness and size. Once the workpiece has reached a temperature of about 300 deg celsius you offer up the solder. The solder must not be melted by the hot air itself but by the temperature of the workpiece.
When soldering without flux, apply a solder cream, paste or soldering fluid to the soldering point before heating. These substances must be washed off with warm water after the soldered joints has cooled down (to prevent the risk of corrosion).
Spot-soldering should be performed with reduction nozzles, pipe soldering with reflector nozzles.
