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!

In addition to your statutory rights (listed on the website separately), the seller offers a 12 month warranty on all products used for private household use from the date of purchase (unless noted otherwise). The use of products for commercial purposes qualifies the purchaser to a 3 month warranty period.

Until the nature of any fault is determined, the resolution the seller can offer may vary. Where necessary, the item may need to be returned to determine fault/issue. If the products are unusable upon receiving or there is a major fault, the customer may choose between a full refund via the original payment method or a replacement product. There may be some situations that result in a reduced refund. In the case of a minor failure, the seller warranty may cover fitment of replacement parts or offer replacement parts to the customer. Other alternatives may be offered to the satisfaction of both parties.

Should you wish to claim a warranty on your item, please follow the process outlined in the Returns section.
