01WELDING GUNS & PLASMA CUTTERS
Precision welding in a portable frame
Positioned on the workbench or tucked into the workshop corner, this unit presents a dense, capable form factor that belies its versatility. It is an instrument of precision, ready to transform raw metal into structure.
The Rossi MIG-140 serves makers who require range across multiple processes. It suits those working with diverse alloys, offering consistent current flow whether using gas-shielded arc, stick electrodes or TIG lift-start techniques.
02TECHNOLOGY
Inverter engineering for stable arcs
At the core lies true iGBT DC inverter technology, ensuring an immediate ignition and deep penetration into the base material. The system employs advanced SYN-WELD TECHNOLOGY, which provides adaptive arc force to maintain a consistent current flow. This stability results in clean, predictable welds without the erratic behaviour often associated with lower-grade inverters.
04VERSATILITY
Multiple modes for varied metals
The machine handles most steel alloys and highly conductive metals, including stainless steel, cast iron, copper and brass. It supports MIG/MAG welding with Argon or CO2, as well as MMA stick welding and TIG Lift-Start. Whether using solid wire or flux-core materials, the onboard adjustable wire feed ensures compatibility with different shielding conditions and electrode types.
05PRACTICALITY
Cooling and portability considerations
A high-volume fan facilitates effective heat dissipation, allowing for continued performance during extended sessions. The compact build keeps the unit manageable, with the packing carton measuring 65 x 30.5 x 41.5 cm and weighing 13.9 kg. This balance of power and size makes it suitable for workshops where space is limited but capability is essential.

About this product
Introducing The Rossi NEXT GEN welders, more power, more versatile, more efficient. The MIG-140 is a powerful 140 Amp DC MIG/MAG/MMA/Arc/TIG Lift-Start inverter welder with iGBT technology. This welder handles most steel alloys and highly conductive metals. It is the must-have multi-purpose welder for anyone who needs a powerful, lightweight, portable welder.
Compact and featuring true iGBT DC inverter technology, you’re assured an instant start and deep penetration. Using advanced SYN-WELD TECHNOLOGY, the ROSSI MIG-140 Adaptive Arc force provides consistent current flow for exceptional clean welds. The advanced cooling system with its high-volume fan ensures effective heat dissipation for continued performance and durability. These features make welding with Argon or CO2* even easier.
With an efficient pure copper Toroidal Transformer and output current that is adjustable between 20A and 140A, you can achieve a quality weld on a wide range of base metals; steel, stainless steel, cast iron, copper, brass, and other highly conductive metals. The high-quality transistors in the bridge combine to make a continuous current rectifier, giving high speed and precise regulation and continuity of the welding current to produce superior results with the onboard adjustable wire feed, general stick, electrode, and special-purpose rods. It is compatible with solid or flux core materials depending on welding with or without gas.
When TIG* welding you can achieve consistent, highly aesthetic welds thanks to the SYN-WELD TECHNOLOGY. When stick welding, this awesome unit is capable of running a wide range of electrodes. It is well suited to stick welding thicker metals outdoors and even in windy conditions, and easily handles painted, dirty or rusty metals. And with standard DIN connections getting additional accessories is a breeze.
Whether you’re welding at home or work, the Rossi MIG-140 DC Inverter Welder will give you a quality weld every time!
