Hey Vicki,
Thaks for joining in. I will try the steel wool tomorrow morning to see how it lifts the haloing. This is something that had never happened before this so ... I hadn't had to find a solution to it
Woodie,
To quote a favorite TV German WWII officer "I know Nothing!" about the why behind the heavy cords or why three different grades.
There seems to be a different in feel (and that's all this is - a judgement call by a non-techno geek) between the Colwood cord and the RazorTip cord. The RazorTip 'feels' lighter in weight or thickness then the Colwood. I noticed this right off and made note of it back in the visual part of this thread.
The Colwood cord is nicely flexible during work and moves well in relationship to the pen, no problem here.
In my experience, this is just my experience, the RazorTip cord can become too flexible and sort of limp. It gives me lots of movement but I have had a couple of times that, being too focused on the burning, I didn't realize the cord had crept (sp)/slipped/moved very close to the pen tip.
The last time I was pulling the tip towards me in a long stroke and just about burned into the cord ... AH! So I grabbed a large paper clip and a couple of big metal washers to hang on the cord about a foot away from the pen. That has added just enough weight that the cord stays out of my way.
The last thing I want to experience is the shocking sensation of my pen tip burning through my pen cord while I am holding it ....

That experience did teach me to not only pay close attention to where I am burning on the wood but also to keep checking my surrounding areas on the table.
Again, not having any understanding of electric work ... could the heavy cord gauge be part of why this pen tip doesn't lose heat when it hits the wood ???
Bill,
Excellent suggestion. I will see if I can obtain the heavier cord. That would let me try it and also try out how easy or hard exchanging the cords would be with their back arrangement .... But, you realize, again, all I could post here is my impressions, feelings or experiences, nothing as tangible as 'gee, this increased the temp setting 15% in ratio to the whatchamacallit on the whozeboob connector ...
