I just set my iron to 300c and it worked this time the 4awg wire is stuck to the damaged led but I did notice the LED got extremely hot whilst doing this.
Will this not damage the LED?

It's difficult to say for sure because of the wire gauge you're using, but 300C isn't specifically too hot... it's more about the amount of time the heat is applied to the contact point. If you have a small driver laying around you can power a single LED with you could do a test to check. You could also try a temp setting of 250 but if it takes longer to heat the wire you could run into the same issue. Maybe try tinning the pad and going straight from tinning the wire to the pad while the wire is still hot. You will just have to experiment and see what you can come up with. Also, since leaded solder has a lower melting point it might be a better choice for this particular application.Will this not damage the LED?
Forget that lead free shit, it is a total pain in the ass to use. Get some 63/37 tin/lead rosin core solder.Ah right I was going for lead free I thought it was supposed to be better
I just ordered a new solder thinking this one might be better

Am I best off buying a different one?
I just ordered 60/40 flux core is it the same?Forget that lead free shit, it is a total pain in the ass to use. Get some 63/37 tin/lead rosin core solder.
Watts are not relevant - only the current going through the wire is relevant to wire size choice.Bare in mind im using a 600w driver in parallel
8AMP will go across the wireWatts are not relevant - only the current going through the wire is relevant to wire size choice.
Better, but 63/37 is ideal. It has the lowest melt temp and no plastic state. Make sure the core is rosin flux and not acid flux. Acid flux core is very bad for electronics.I just ordered 60/40 flux core is it the same?
You have to Solder wires BEFORE on the heatsink otherwise it pulls the heat away. like it should .I can screw cobs in fine. Reason for holders is I'm struggling to solder the wire to them..
4awg wire is so thick that I can't seem to get the solder to melt fast enough and get the wire to stick to the holder.
I destroyed an led by leaving the iron on it too long trying to melt it
