182deg/C is just the melting temperature of 60/40 soldering tin.
For a good connection (mechanically and electrically) the soldering temperature must be high enough to have the tin flow around the component pin and distribute evenly on the solder pad.
250deg/C is a bit low while 270 to 290deg/C is about right for small parts.
If your soldering iron is able to produce 450deg/C it is also well suited for big parts like AMP-connectors.
Best purchase is a temperature controlled soldering station.
