Steve max is actually 830F. I run 3 tips. The T15-D2 Heavy, T15-BLL for fine work and my general tip T15-D12. The thing I like about the Hakko is you can quickly change tips. Turn it off, swap tips, and power back up. Of course you could do the Navy soldering method. Hold the connector and wire together, wrap a bit of solder to hold them in place, stand behind an F18 Super Hornet in afterburner just prior to launch, extend hands holding connection into the exhaust core. This method is very quick.
