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 quick
connect fittings. 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 LX Fronius
Compatible gun. The gun end of the cable is secured with a cable clamp and
the wires are connected to the potentiometer, micro switch, 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 of the
control cable uses a 9-Pin, rectangular connector.
Section B Operation
General
The Python LX Fronius 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 lever 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
