Default 7hv manual question (80w soldering iron)

The manual states that an 80w iron should be used. Is this essential?I have been using a 30w iron through out the 6hv's life with no problems?

If you've got this far with it why change.
As long as you can solder Motor Bullets and Battery Connectors fine you need no more.
Higher wattage does do a nicer job and makes it faster easier, but if you aren't overheating/melting stuff your good.

There is a risk, if you are not experienced/know what to look for, that you could end up with a cold solder joint, especially when looking at 6 to 6.5mm bullets. I use a 40W and it does the job, but 80W would be nice. After applying heat, my iron needs a minute to come back up to temp.

Another benefit of a higher W soldering iron is less heat transfer in your components.
If you have to keep it on for a extended time to reach the right temperature, everything heats up.

+1! The key is to get in and out as quickly as possible. More wattage makes that possible.

That's probably the best argument for a higher powered iron, forgot about that, but you remember when you're holding onto a wire, burning your fingers.

Two more things... too much wattage is just as bad as too little. Just right for larger wires is around 80-100 watts for 10 gauge wire and larger bullet connectors. Keep the tip clean and tinned; it will aid proper heat transfer.

Thanks a lot guys. I have gone for a 150w adjustable iron as I think I might have a hard time with the larger connectors. Thanks for the advice lads.
