Hi,
please let me know how to improve: the goal is fully weld all the way to the center with minimum cross-over
test one:

parameters: 130kV, 70mA, 5mm/s, under-focus 5mA - diameter 96mm

test two:

parameters: 130kV, 75mA, 5mm/s, under-focus 20mA- diameter 96mm
notice the porosity near the center due to cross over

what to change?

Welcome Miketheexpat. You took a wrong turn somewhere and landed in the Welding tips & tricks forum. Here we do down & DIRTY welding. We dont do no stinkin ebw! Good luck with your endeavor. You might need to pay for professional engineering consultation for something like this..

Looks like your flux capacitor may be on the fritz.
