Goot! now there's another high quality iron.I have one of these also that I use for traveling it works extremely well.Even with a smaller tip it gets up to over 1000 degree's

For ALL R/C related work you want a good chisel / screwdriver type tip. When I see folks at the track using the rounded / pointy tip I just wanna cry. By using a flat tip you transfer the heat much faster to the joint through sheer surface area. Using the rounded side of a pointy tip makes you have to hold the iron forever due to lack of surface area and you risk destroying your equipment due to overheating.

Also...ALWAYS USE FLUX!!!!! For the life of me so many in the RC world seem to of never heard of flux. They'll say that the solder has some in it...so what!?!? You NEED to brush a light coating of flux onto each part to be soldered to ensure a good hot-joint. I know....as I was a crewcheif on CH-46E helicopters while in the USMC. I've soldered and worked on plenty of avionics boxes and was trained to do it right.


Hot-Joint : When solder has completely flowed though both wires and between both surfaces. A hot-joint will always have a very smooth and shiny appearance after soldering and the parts will be strongly joined together. Hot-joints have the best possible electrical conductivity and are extremely strong.

Cold-Joint : When the solder doesn't completely flow between the two surfaces. Typical cold joints on a wire only have solder on one side and visible braid is still seen on the other. Cold joints typically are very chunky and dirty looking plus the luster of the solder is like that of a flat silver. Not using flux and a high enough temperature is the #1 reason for cold-joints. Cold joints have horrible conductivity and are not very strong.

If you need to hold your iron to make a joint for more than 1-2 seconds, you are not using a high enough temperature or the wrong tip...or both.

Wow... Good tips... Thanks...

I have flux, but never use it... mostly because the can is a b!tch to open...

The 40 watt station is the WLC100 and 80 watt is WLC200. I have both and both are adjustable from 5-40 watts and 5-80 watts respectively. I agree the WLC200 is good for batteries. I picked up the MTG21 1/4" tip for the WLC200 and turn the dial down a notch and found it's good to use at the track plus I know I can do batteries if needed. I might start taking the WLC100 to the track and leave the WLC200 at home but I like the extra power.
