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 tortch and wire feeder
motors will begin feeding wire. Retract
the screw accordingly until the system is
deactivated and adjusted to the operators'
liking.
Drive Roll and Idler Rolls
General
The Python
® torch 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.
NO ADJUSTMENT IS REQUIRED FOR ALL SIzES
AND TyPES OF WIRES .
Drive Roll Installation/Removal
Note: Neither of the handles needs to be removed to access the drive or
idler Rolls
1. Pull the cam lever away from
the idler roll. This will relieve the
pressure against the drive roll (as
shown in Figure 1).
2. Align the drive roll removal tool
(P/N 931-0100) over the flats of the
drive roll (as shown in Figure 2).
Hold the torch with one hand or on
a table top, with the other hand give
the removal tool a quick snap-turn
in the CLOCKWISE DIRECTION.
