Hooking up spool gun to Lincoln dc-250

admin

I have a lincoln dc-250 which produces cv current and I want to hook up my miller WC-3 with spoolmatic 2 spoolgun. The WC-3 is the controller for the spoolgun I guess.  I have hooked it up to my lincoln gas driven weldanpower 225 and it every thing works.  But when I hook it up to the DC-250 the spool gun will not work.  I have a manual for both but I am still lost. What am I missing?  Thanks
Reply:I finally got these two units to work together. It took a lot of head scratching while reading both manuals.  Neither of the two manuals over explain how to power up the competitions equipment.  It only took two wires hooked up in the correct place to work.The spool gun will lay down a nice aluminum bead. I am very happy with the outcome,  especially since I did not have to go buy a new mig welder with an attached spool gun.
