Heavy weapon forge

 is a world object in the Fallout 4 add-on Contraptions Workshop.

Characteristics
This large rectangular contraption automatically produces "heavy" weapons when one of the pre-programmed weapon platforms are selected from its software. This machination is operated from a makeshift terminal which has the Schlocket Industries Automated Manufactory Control Panel loaded onto it.

Simply attach a wire from a power source to power the device and attach a second wire to said terminal to operate. The heavy weapon forge requires the third rank of Gun Nut to create, and needs 15 power to be activated.
