Added spool gun to welder tested fine now neither will feed

[JeffreyIII]

Added a spool gun to power mig 200 and tested both guns feed wire. Didn't have any argon gas so could complete testing. Went back to it a couple of days later and now neither gun will feed. Im new to this any help would be greatly appreciated. Thought it might be a fuse but can't locate any inside welder.

Check the control voltage it should be around 24 volts.
