Hi all, thanks for popping onto my thread. I currently have an old Migmate 100, I tried giving it a small service (replaced the torch lining and new tip) and still having trouble with wire feed. So, I have decided to upgrade it as it still works decently. The upgraded parts have cost me nothing so please don't tell me it's not worth doing because I got my whole set up for free, literally. Now for the gritty bit, I've removed the old torch and motor, and am trying to fit a euro torch dual roller system to it, but the Elmotor AB I have aquired has 4 wires instead for just 2 which has me stumped. One is black one is red (I'm assuming that this is obviously to power the motor itself) but there are 2 grey wires poking out of the top of the motor, does anyone know what these are for?
