Hello all,
I just got my used TB 302 DC only unit. It welds great, on the run idle setting it will "idle up" when I strike the ark and will hold the idle up for a few seconds after I am done welding...... NOw If I plug something into the generator side and the unit is in the idle run setting, it will not kick up and produces low power, but if I manually turn it to the run setting it idles up and I have all the power I need, Any suggestions on where to look for what part is in need of repair

Thanks
D
