Kemppi Master M 355G Pulse Water-Cooled MIG Welder – 350A, 415V
The Kemppi Master M 355G Pulse is a premium-grade MIG/MAG welding power source engineered for demanding industrial environments where precision, control, and productivity are paramount. Featuring advanced pulsed welding capabilities, a robust water-cooled design, and intuitive control systems, this 350 A, 415 V unit delivers superior arc performance across a wide range of materials and thicknesses.
Built on Kemppi’s Master platform — renowned for durability, versatility, and performance — the Master M 355G Pulse is ideal for heavy fabrication, structural welding, shipbuilding, automotive production, pressure vessel work, and other high-output welding operations.
Pulsed MIG for Precision & Control
The pulsed MIG function of the Master M 355G enables welders to precisely control heat input, reduce spatter, and achieve superior bead aesthetics, particularly on thin or heat-sensitive materials. Pulsing allows rapid transitions between peak and background currents, resulting in stable arcs and smooth metal transfer across a wide range of applications — from mild steel and stainless steel to aluminium alloys.
Water-Cooled Capability for Continuous Performance
Equipped with an efficient water-cooling system, the Master M 355G is designed to maintain optimal operating temperatures during long, high-duty-cycle welding. This cooling architecture enhances performance and extends component life under heavy industrial use — a crucial advantage over air-cooled units in production environments where welding cycles are frequent and uninterrupted.
Synergic Control for Effortless Setup
Kemppi’s synergic control technology automatically adjusts voltage and wire feed parameters based on the selected consumable, material type, and thickness. This simplifies setup, reduces guesswork, and delivers consistent results — so operators spend less time configuring machines and more time welding.
Industrial Strength & Flexibility
With a powerful 350 A output and rugged build quality, the Master M 355G Pulse handles thick-plate welding while still offering refined control on thinner sections. Its modular design and multiple interface options — including remote control panels and advanced MIG guns — help integrate the unit seamlessly into production workflows.
