Hi alan and all
No the tip will get a little discolored, but hey that was just a 'knock up' when I was putting the tungsten rod in the 'no flame' i thought it was out and was going to 'light it' up again then the rod started glowing.
now there was only a few drops of water going though may be a big few, but no big flow, well I have to go to bed and then go to work, it looks like its going to be another cold night and wet.
will be trying again tomorrow it's the last day that I have the 'power unit'.
