$20000 - $30000 to put 3ph. in where I am.
Getting a good, used, big auto was a challenge, but Workhorse Falcon E fit the bill. My compressor is taxed when running the auto multi-head over 40doz/hr. and running the pad printer at the same time. An additional fan on the electric motor stopped it from thermal shutdowns, but I know I'm running it too hard at peak production.
