A little more information for anyone following.
I loaded the spring pressure so as gearmotor near stalls on cam lobe.
Makes it about a 2second cycle.
Welder foot switch starts the cycle. Welder output can be delayed. I have .5sec delay, then 1.25sec weld time.
I need a way to monitor on time for better adjustment. If nothing else, an inline ammeter on input may suffice. May be something built in, but the rep doesn't even know about the weld delay and auxiliary output to control press.
On a good weld display shows .46a after a weld. No idea if I'm using near capacity. Again there is zero support.
