Hi I’m looking for a controller to run our custom welding robot.
-6 axis
-arc welding functions
-pendant teaching control
-using steppers so dir / pul signals are required.
-teaching logic and playback
-200-230v
I have tested some cheap Chinese controllers that do the job, but are just not very refined. I'm thinking the Kuka KR C4 might be a good option or maybe Nidec. Can anyone shed some light into these controllers or another option that may suit.
Thanks
