    i have problems with my mig.
    It´s has a half bridge rectifier also.
    On the photo you toke measures on ac or dc?
    My mig on paper says 20 amps (16v) to 140 amps (20v) so it is a close match to Clarke 135TE Turbo.
    I toke my readings on the positive and negative dinse terminals for the 4 settings while pressing the toch trigger .The difference was about 4 volts.
    Min +1 -18.8vdc
    min +2 - 20.2vdc
    max+1 -21.7vdc
    max+2 -23.3 vdc
    can you take measure of the volts on the 4 settings? thanks

    Those voltages are all fine.
    You mean measure the actual welding amps?

    You need a large screw terminal block, used to be called brothels, pc gone mad.

    i´m measuring only the voltage, i tryed to measure the amperage but i only got 50/60 amps on max +2 the wire speed doesn´t help cause the motor only got 24v on 10 of 10 on the dial. at 9 of 10 it only gets 18v .

    For max+1 or min+2 i get these readings for motor voltage
    1-0,6 v
    2-0,95v
    3- 1,35 v
    4- 1,8 v
    5 - 2,3 v
    6- 3,6 v
    7 - 5,6 v
    8- 8,5 v
    9- 15.6 v
    10- 18,8 V
