    Default Spool Gun Adapter Contactor

    So Miller discontinued parts won't stop a redneck welder from getting the job done! Found a Spoolmate 3035 at an auction CHEAP! Unfortunately it didn't come with a controller with contactor to run on my Bobcat 225. Searched high and low for a used SGA-100c for several weeks with no luck. Finally found a used SGA-100 in Wisconsin so I made my own contactor!

    Yup. That's one effective way to do it. Good job.

    I choose to just add a 14-pin to my Bobcat with a 240/24V transformer for 24VAC on pin "A", 115VAC on pin "I", a LOCAL/REMOTE selector switch and a 115VDC 200A contactor from a $50 ProFax 200-C off eBay controlled by or thru a 24VAC relay depending on which return input is being used thru the 14-pin.

    Now I can run pretty much any Miller 14-pin accessory on Bobcat with ease.

    Nice! If this spool gun were a 14 pin I probably would have looked into that route. At least the parts diagrams were helpful from Miller, I definitely saved a lot of money the route I went. A new SGA 100c is almost $500.00, the used SGA 100 (which looked practically brand new) I had the metal box, electrical contactor was $20.00, <$5 for stainless steel bolts/nuts, small bolts/nuts <$5.00, new copper lugs <$5.00, I made the plates to connect the lugs on contactor out of stainless steel I had, got it all done for right at $200.00...Not bad
