I have a SIP Migmate Super Dual Purpose welder. I bought it new in 1988. About 3 years ago the drive motor quit on it. I believe the motor has a bad spot in it. If you turn it to a certain spot it will run
till it hits a dead spot in it. I tried to take it a part, but doesn't seem I can get the metal ears to unbend to disassemble it. The drive unit is 10089, seems to be the same as SIP is still using on some of their newer models.
Long story short, I could never find a replacement here in the U.S. for it. SIP no longer has a distribution network here anymore. This last month I was able to purchase replacement feed motor assembly for a Clarke welder. Looks pretty much identical to 10089 SIP drive unit. it does not have the ear for the torch mounting though. Anyway, I figure I can reuse my gearbox. The gears look fine in it and just change the motor over from the replacement drive I bought.
Problem, SIP tells me their drive motor is 24 volt rated, the replacement I bought for a Clarke has a sticker on it that it is only 12 volt. is it as simple as inserting a resistor in series with the motor to drop the voltage going to the 12 volt motor?? They give a diagram in the SIP manual that came with the original welder, but no values for the various resistors, caps and the transformer that is mounted on the PCB board.
About the only problems I ever had with the welder was the contacts on the relay wanting to stick (which was corrected by mounting a large external relay to carry the welder.
Thanks John
