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 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.

Drive Roll and Idler Rolls

General

The Python® Lincoln Compatible™ 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® Lincoln Compatible™ 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.
