Weldotron 1022 Fastpak Automatic L-Bar Heat Sealer 230v 3ph Heat Shrink Packager

Used. Powers up.
Lots of sensors. We were not able to cycle the machine as it was use for a certain size product.
L sealer heats up as it should. The Dwell time does not receive power or light up. Not sure what this does. Key parts function.
