Section B Operation General The Python® maintains a constant, steady, uniform wire feed speed, regardless of curved or looped wire conduit. The constant push exerted by the slave motor in the cabinet, combined with the pull of the gun motor, causes the wire to literally float friction-free through the wire conduit. The 24VDC gun motor is controlled by a three and three-quarter (3 3/4) turn potentiometer in the gun handle.
NO ADJUSTMENT required for ANY WIRE SIZE AND ALLOY Drive Roll Installation/Removal Note: Neither of the handles needs to be removed to access the drive or idler rolls. 1. Pull the cam lever away from the idler roll. This will relieve the pressure against the drive roll (as shown in Figure 1). 2. Align the drive roll removal tool over the flats of the drive roll (as shown in Figure 2).
