Coolant Connections
If so equipped, the ends of the coolant hose push over a barbed fitting on
the end of the gun body and are secured by twisting the hose retainer to the
end of the hose. The hose retainer is re-usable and can be removed and
re-installed as needed.
The BLUE coolant supply hose pushes over a barbed fitting on the end of
the gun body and is secured by twisting the hose retainer to the end of the
hose. The hose retainer is re-usable and can be removed and re-installed as
needed.The opposite end of the BLUE hose pushes into a threaded coolant
fitting.
The RED coolant return hose pushes over the barbed fitting in the Power
Manifold. The opposite end of the RED hose pushes into a threaded return
hose of the coolant recirculator.
Both threaded fittings on the end of the BLUE and RED hoses are standard
left-hand thread. MK Products compatible guns have interchangeable fittings,
so you can match as needed for your cooler. Both types of fittings require a
hose retainer.
Control Cable
A multi-conductor control cable is used on the Python Lincoln Compatible.
The gun end of the cable is secured with a cable clamp and the wires are
connected to the potentiometer, the micro switch, the motor and the gun
body mechanically. Slack is left in the electric cable as it exits the back of the
gun to prevent cable and/or wire breakage. The cabinet end has a seven pin
"W" clocked amphenol connector.
Section B Operation
General
The Python Lincoln Compatible 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 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.
Controls and Settings
Potentiometer
The laterally-positioned potentiometer is located in
the lower end of the handle, providing up to 800 ipm
with 3 3/4 turns.
Micro Switch
The micro switch assembly consists of the micro
switch, and leads.
Trigger Sensitivity
The amount of trigger level travel can be shortened
for a "quicker" or "more responsive" action.
A more sensitive trigger lever is produced by
reducing the gap between the trigger lever and
the micro-switch lever. By turning-in the Trigger
Sensitivity Adjustment Screw, it closed the gap
between the trigger lever and the micro-switch
lever.
