Not sure about 45, but I have a 30 watt weller that works well (lol pun) for me. It heat joints much quicker, so cart slot relocations and the like don't take as long.Basement_Modder said:More watts=more heat=more likely to burn and *Can'tSayThisOnTV* up the board.
However, 45 watters with small tips are great for RCP wiring/ exp. pak relocations, as you can touch for 1 second and it's done.
