Section A Installation Technical Specifications Wire Capacity .030" - .045" (0.6mm - 1.2mm) solid and hard wire .030" - 1/16" (0.8mm - 1.6mm) aluminum and cored wire Wire Speed 800 IPM (20.3 mpm) Max. at rated feeder Input Voltage (120VAC / 42VAC) Duty Cycle - 60% All ratings are using Argon Gas 225 Amps/25 Volts Air cooled standard 250 Amps/25 Volts Water cooled standard 450 Amps/25 Volts Water cooled optional Support Equipment Required • C.V. or C.C.
Gas Hose The gas hose is secured over the barbed gas fitting with a tie wrap. The cabinet end of the gas hose uses our standard gas fitting (1/8” - 27 nps). Water Hose If so equipped, one end of the water hose is secured over the barbed water fitting with a tie wrap and the other end is connected to the center fitting on the power block. Electric Cable A seven conductor control cable is used on the Python® gun.
Drive Roll and Idler Rolls General The Python® gun comes standard with a knurled drive roll and a grooved idler roll, which will handle both steel and aluminum wire with diameters from .030-1/16 inch. Optional insulated V-groove drive rolls are also available for aluminum wire if desired (see Optional Kits). Drive roll tension is accomplished with a unique spring-loaded pressure screw. The Python® comes from the factory with the pressure adjustment screw preset.
Section C Accessories LE P/N MK P/N Optional Kits 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. Insulated Groove Drive Roll Kit ..........................KP1594-030 ....... 005-0640 For .030" (0.8mm) dia. aluminum wire.

Section E Troubleshooting T rouble 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. Wire feeds one speed only. Cause Re me dy 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 gun 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 gun 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.

CUP INSULATOR AND O-RING MAINTENANCE CAUTION: Power-off the coolant pump before disassembling water-cooled barrels. 1. Unscrew Retaining Nut and slide back on barrel. 2. Using a firm pull and twist action, the Water-Cooled Gas Cup or Air-Cooled Gas Cup Assembly can be removed from the Cup Insulator. 3. Inspect the Cup Insulator and o-rings (included with Insulator) for wear and proper lubrication. It is considered good practice to replace all o-rings at the same time. 4.
