First time poster, long time lurker here
Recently picked up a second hand
Stahlwerk Mig-Mag 200 , the machine runs smoothly on stick and will weld a good bead with the Mig , but only at higher voltages as the wire feed speed is meant to auto adjust with voltage , but from what I and a professional welder can make out , it appears to be stuck at one , fast , speed , anyone have experience on these types of feed controllers ? Any help would be much appreciated

Try the forum. I know of no other european welding forums. I suggest contacting the manufacturer for a service manual.

it runs the wire feed motor directly off the output voltage, because that's the cheapest and nastiest way to do it.
the tortoise/hare switch is your only external adjustment, but there'll be a trim pot somewhere inside the machine.

I'll try look for it , don't recall seeing a trim pot when I've tried to trace the power to the motor , but I may have missed it , also when toggling the tortoise/hare switch there was no difference in the speed at all. However I know the motor can run at a lower speed as there is an 'inching' button internally that puts the motor on constantly at a low speed
