Yeah... most people probably just grab the temp control and crank it to max.
Yea,
I have seen that and when I see people do that I educate them on proper use of the tool, temp control, solder choice, keeping the tip clean etc. The end result they come away with good connections and knowledge!
The solder manufacture will tell you the temp range the solder works best at there are so many mixes of solder so also using the right mix and thickness for what you are soldering is a must for a good solder jolint! But that is another subject for a later thread!
I was in the electronics industry for about 10 years have worked on simple stuff to reflowing "BGA" ball grid array!
I have fixed enough Autoshop/Stereo Shop, Fly By Night TV Shops, solder joints to last a life time!
The Last one was some monkey spliced in a new injector connector and used what looked like plumbing solder from home depot or autozone and the resistance load was to high = PCM error on that injector the shop told the owner that his PCM was bad! No it was a bad splice/soldering job!
Another was instrument panel lights and stepper motors on a GM 2500 PU dash. The monkey that worked on that over heated the PCB and lifted some of the traces off the board and every connection that he kept the traces in tact was cold solder joints!
