CR1 relay needed for syncrowave 350

go to see Welding Machine for CR1 relay needed for syncrowave 350

My syncro 350, which is a '91 model I believe, just lost the high frequency on the arc start function only. The hi-freq still works fine when the switch is set to the continuous position. All the searching I have done, both on weldingweb and on the miller forum, points the finger at the CR1 relay. Blocking the relay contacts open with toothpicks does activate the hi-freq with the switch set to arc start. I am using a foot control to initiate the arc. I have spent some time trying to source this relay. Miller has discontinued it, and it is no longer in stock. Midtex Relays, Inc. is the oem of the relay. Their part number on the relay is 626-0251. They do not have it either. They also have sold out to another company. I believe Miller's part number is 052251. Any suggestions? Does someone know of another relay that works? Or do you have a spare for sale? Needing some help on this one. Thanks! Ken
