Python-Plus Owner's Manual - Page 2

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 fl oat 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.

The laterally-positioned potentiometer is located in the lower end of the 
handle, providing  up to 800 ipm with 3 3/4 turns.

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.

This well enable the operator to increase 
the sensitivity of the trigger lever.

Sensitivity Adjustment
With the wire feeder turned on (with or 
without welding wire loaded), turn the 
screw in until the micro-switch is activated. 
Once activated, the gun and wire feeder 
motors will begin feeding wire. Retract 
the screw accordingly until the system is 
deactivated and adjusted to the operators' liking.

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.
