Hi Bruce, yes I have been re-melting welds to improve them. I'm now typically only grinding/filing off if I have run totally out of position.

Hi Frank, the better welds are indeed where I upped the MAX-amps and played the pedal. As a relative beginner I find it so annoyingly easy to get out of position on tubes. The only problem is that I have (on occasion) blown a hole and had to fill it back in.
