that or apply some no-ox-id to the contacts. I read about it on another thread and (hope I don't jinx myself) have not had any arcing issues since. I am truly amazed at how well that stuff works. I've started using it on all the contacts on all of my mech squonkers and it really does a great job of preventing corrosion and the need to clean contacts.Do it. Awesome little thing for the money.
I use mine as a backup to my DotSquonk.
Just keep some sandpaper around for the arcing.
