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?

Looks like your flux capacitor may be on the fritz.
