The Lincoln Electric K488 Magnum SG Control Module is an industrial interface unit designed to connect the Magnum SG Spool Gun to Constant Voltage (CV) power sources and engine drives that lack a dedicated spool gun connection. It functions as an intermediary control unit, drawing 115V AC power to drive the spool gun's wire feed motor and managing gas flow through an internal solenoid. The module interprets the trigger signal from the gun to engage both the power source contactor and the gas flow, bypassing the machine's internal wire drive to allow wire feed speed control via the potentiometer on the spool gun.
Features
Provides control of wire feed speed and gas flow
Internal gas solenoid valve manages shielding gas flow synchronously with trigger pull
Interprets gun trigger signal to engage power source contactor and gas flow
Bypasses machine internal wire drive to utilize spool gun potentiometer for wire speed control
Heavy-duty solenoid construction
Interfaces with power sources lacking 6-pin or 7-pin amphenol connections
