  • wire speed control issue on handler 135

    i have a handler 135 and the wire speed is stuck on 100. it doesn't change when you turn the knob. are there any known problems for this? is there any test i can do to find the problem?

    thanks for the help

      Does it have a reset button? If so, it has gone bad, if not there is a fuse or something inside.

        The board will need to be replaced or repaired. When the WFS goes to max it is usually Q1 on the board that needs replaced if repairing the board.
