I am in the middle of a quandary at work. We have wire feeders that obviously control the feed rate of wire through a welder. We have need of putting these units up out of the way and what I did to accomplish this is to move the 10K pot from the feeder unit to the hand-held "whip" Because the knob on the new pot (also 10K) is now considerably smaller it is very difficult to fine tune the wire speed. The usable range for wire speed is approx 30%-60% as indicated on the original dial.
How could I solve this problem? Change the value of the "new" pot in the hand-held unit? Parallel? Dropping resistor across tab 1 and tab 2? Am at a loss.
