Section B Operation General The Python gun 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 torch motor, causes the wire to literally float friction-free through the wire conduit. The 24VDC torch motor is controlled by a three and three-quarter (3 3/4) turn potentiometer in the torch handle.
Drive Roll Installation/Removal NOTE: Neither of the handles needs to be removed to access the Drive or Idler Rolls. Cam Lever 1. Pull the Cam Lever away from the idler roll. This will relieve the pressure against the drive roll (as shown in Figure 1). Figure 1 2. Align the Drive Roll Removal Tool (P/N 931-0100) over the flats of the drive roll (as shown in Figure 2). Hold the torch with one hand or on a table top, with the other hand give the Removal Tool a quick snap-turn in the CLOCKWISE DIRECTION.
Section C Accessories/Options LE P/N MK P/N Insulated Drive Roll Kits are used to prevent preheating of the wire which may soften it and clog the liner. This picking up of current at the drive rolls rather than at the contact tip is usually not a problem unless using too large of a contact tip or excessively oxidized aluminum wire.

Barrel Assemblies All barrels are rated at 100% duty cycle Barrels Air Cooled The Python-Pluss guns come standard with a 60˚ curved barrel. The barrel assembly locks to the Python® body using the patented EZ Lock™ system. Barrel Removal and Installation To remove the barrel assembly, loosen the patented EZ Lock™ Taper lock nut until it is clear of the threads. Pull barrel out of the gun body.

Section E Troubleshooting Trouble No wire feed at torch, feeder not operating, i.e. no slave motor or brake solenoid. No wire feed at torch, feeder operating properly. Wire feeds, but welding wire is not energized. Wire feeds erratically. Cause 115/42 VAC Control fuse in Replace fuse. feeder/Control box blown. Micro-switch defective/not being activated. Replace switch. Check switch for operation. Broken electrical cable. Check micro-switch wires for continuity.
Troubleshooting Guide Regardless of which torch or feeder used, all MK Products’ push-pull guns operate on the same principle. The slave motor in the feeder runs at a fast, constant speed, but has very low torque. It is always trying to feed more wire than the torch motor wants, and when the motor gets all it wants, it slows the slave motor, preventing a bird’s nest. Because of the low torque produced by the slave motor, a brake system is used to prevent wire overrun rather than tension.
