• OneTouch synergic adjustment with 40 pre-set curves and LCD display for wire speed, welding voltage and current. Selectable 2T/4T modes and spot welding.
• MMA: DC and pulsed modes (MMA PULSE). VRD safety device. Gouging function. TIG: DC-Lift striking.
• Special ventilation tunnel protects electronic components from dust and dirt to increase reliability and service life.
• Durable, dust- and impact-resistant construction with reduced weight and high energy efficiency.

Description
The MAXMIG 450i BASE is a flexible multiprocess inverter welding system designed for heavy professional workloads and harsh environments. It supports steel, stainless steel, high-strength steels and aluminium across MIG-MAG, FLUX, brazing, MMA and TIG DC-Lift processes, plus gouging. ONE TOUCH synergic setup simplifies parameter selection: choose material and thickness and start welding. The graphic LCD provides immediate feedback on wire speed, voltage and current while intelligent arc control (ATC) stabilizes the arc across varying conditions. Operators can fine-tune arc length and parameters manually from the wire feeder for process tailoring.
