Use Cobra Coolant (Aluminum Protection), P/N 931-0060.  Cobra Coolant 

does not contain reactive sulphur or chlorine and does not react with copper, 

brass or aluminum.  

The coolant flow rate should be a minimum of 15 GPH (1 qt/min) between 

35 and 45psi.  Contact the re-circulator manufacturer for specifications on 

pressure.

The Millermatic Compatible™ Python 

®

 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.

The laterally-positioned potentiometer is located in the lower end of the 

handle, providing  up to 800 ipm (20.3 mpm) with 3 3/4 turns.
Micro Switch

The micro switch assembly consists of a normally open micro switch and 

solder-attached 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 trigger lever and the micro switch 

lever.
This will 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' satisfaction.

 comes standard with a knurled drive 

roll and a grooved idler roll, which will handle .030" to 1/16" aluminum and 

.030" to .045" solid and hard wire.
