D. Routing Of Torch Leads
1. To minimize RF interference, position torch leads as
far as possible from any CNC components, drive mo-
tors, control cables, or primary power lines. If cables
have to pass over torch leads, do so at an angle. Do
not run the plasma control or other control cables in
parallel with the torch leads in power tracts.
2. Keep torch leads clean. Dirt and metal particles bleed
off energy, which causes difficult starting and in-
creased chance of RF interference.
3.09 Tip Saver/Drag Sensing Circuit
This power supply is equipped with a Tip Saver/Drag
Cut Sensing Circuit which reduces current to 35 amps if
the tip touches the workpiece. The purpose of this is to
prolong the life of the tip.
If the user does not want the current to be decreasedwhen
the tip touches the workpiece, the sensing circuit can be
defeated by closing switch SW1-1 on the Gate/Logic PC
Board. Slide top white toggle on SW1-1 to the right to
close circuit.
