Yes, when adding wire we recommend soldering new wire in place for the most robust connection, the polarity (+/-) is marked on the strip light. Alternatively solderless wire clamps are available for our non-waterproof strip light.
Tinning is applying the solder to each part first. Tin the wire and then Tin the strip light copper joins , hold together and apply a small amount of heat to melt solder together to join. Doing this stops the strip light from being overheated (being quick) and the join is clean with less chance of a short being created. You can also use FLUX to help with solder pooling for a better connection and flow.
