Control Cable
A multi-conductor control cable is used on the Cobra
MX
Euro Compatible 7
Pin. 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 Cobra
MX Euro Compatible 7 Pin 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
micro switch lever. By turning-in the trigger sensitivity
adjustment screw, it closed the gap between the
