Its kind of guesswork, but the key is attaching the alligator clip
at the proper distance from the spot that will be welded. The
thinner the metal between the clip and the weldspot means you must
place the clip further away. Thicker metal allows you to place the
clip closer to the weld spot.
Hm, I’ll have to try that. I still don’t know much about welding
with it. But that would definately explain why when welding
jumprings closed some weld perfectly while others either don’t want
to weld at all and others over weld and leave annoying balls.
Though I’m not sure I can get the connection much further away
unless I wrap a piece of wire around it and connect the lead to that
so it’s futher off.
I’d also appreciate any other PUK/Pulse Arc welding tips anyone
might have, relevant to this or not.
