The electrodes shouldn't get hot to the point of glowing .... at least on mine they don't ??

I do have one of those John and will give it a try. Now sure though that the 300W will be enough for that large a heat sink but it's worth a try, thanks.

I think you'll find that a 300W soldering gun will put out a lot of heat.

for a little more heat on the 300 watt iron, replace the tip with a piece of ordinary house wall wiring, in 14 or 12 gauge ... they make excellent tips, and the cost is very low .. solid copper wire ..

WVGCA, I tried a lower setting and get some glowing almost instantly. I am troubleshooting that with the company I bought the machine from. Not sure what is happening.

John, I was wrong the Weller I have is the 140W model. I still tried it and definitely doesn't put out enough heat. I'll will try and make the resistance machine work before I buy that 300W to try. Gotta justify that 2500$ price tag.

$2500??? Where did you come up with that price???

Weller D650 Industrial Soldering Gun, $56.99.

You could also consider the Wall Lenk LG400C 400W/150W Heavy Duty Watt Soldering Gun, $78.00.

Oh no John I meant for my resistance soldering machine. It's from American Beauty. Got 2 handpieces with a few extra tips. Add shipping, taxes and duties.

I can't help you with an existing purchase, but it's dirt cheap to explore the alternatives, especially based on spending $2500 on a solution that isn't working for you!

the Weller, if it's the same as the one i got, is 100 watt low, and 140 watt high ...
the household wiring thing works great .. it -may- be enough , easy to try it out ??
