Son's welder broke, he's trying to find a place he can get a new contactor for a miller 185 here in the denver area tomorrow (Sat).

Anyone got any suggestions of places that might carry this type of part?

The part in question is the "contactor", part number 189 486 shown in the miller manual. The specific part number on the part removed from the welder shows as Furnas 42CE107102J


Any pointers to a place around denver that might carry similar parts would be great.
