K5379-1 - Lincoln POWER MIG 220 AC/DC Multi-Process Welder K5379-1

Advanced Multi-Process Capability for Industrial Fabrication

The Lincoln Electric POWER MIG 220 AC/DC Multi-Process Welder (K5379-1) is a versatile powerhouse designed for the general fabricator, maintenance professional, and small contractor. Unlike many multi-process units that only offer DC TIG, this machine features full AC TIG capabilities, making it a true all-in-one solution for welding aluminum, stainless steel, and mild steel. With a robust output of up to 230 Amps for MIG and 210 Amps for TIG, it delivers industrial-level performance in a compact, portable chassis.

Precision TIG Controls

For precision applications, the POWER MIG 220 AC/DC excels with advanced TIG features typically found on dedicated TIG machines. It includes adjustable AC Frequency and AC Balance controls, allowing operators to fine-tune the cleaning action and penetration profile when welding aluminum. The inclusion of Pulsed DC TIG further enhances control over heat input, reducing distortion on thin materials. The machine comes factory-equipped with a Caliber 17 flexible-head TIG torch and a Foot Amptrol, ensuring you have the necessary tools for high-quality TIG work right out of the box. The built-in TIG solenoid and foot pedal adapter streamline setup, eliminating the need for bulky external gas valves or complex retrofits.

Intelligent Interface and Dual Voltage

At the core of the user experience is a 7-inch color TFT display featuring Lincoln's Ready.Set.Weld technology. This intuitive system guides operators through setup by recommending optimal parameters based on material thickness and wire type. ArcFX technology provides immediate visual feedback, illustrating how adjustments to wire feed speed or voltage will affect the weld bead profile. The unit's dual-voltage capability (120V/230V) ensures operational flexibility, allowing connection to standard household power or industrial mains. Weighing just 51 lbs and designed with an ergonomic case featuring multiple lift points, the POWER MIG 220 AC/DC is engineered for mobility without sacrificing structural integrity or power.
