Eastwood's MIG 140 Welder
Our Eastwood R&D guys have been constantly improving our incredibly popular MIG 135 since 2009 and are proud of this newly designed and improved MIG 140 that's great for light metal fab and all of those sheet metal projects and repairs that are necessary in auto restoration. The modern IGBT Inverter technology means a lightweight, portable, powerful unit that can even be powered by a generator. The new 2T/4T modes and tack weld feature add comfort and performance to this machine.
The high quality welds in sheet metal and thin steel as well as the overall performance matches and often exceeds more expensive MIG welders. This 120v unit comes with a Tweco-style torch, gas regulator and consumables for MIG welding up to 3/16-inch thick. It’s also capable of doing flux-core work when you don't have a gas bottle. You can even add a spool gun to weld aluminum (item 20172).

Weld Aluminum with a Spool Gun

Quickly and easily connect or remove it as needed for working on different parts and panels. The spool gun is sold separately and is a great addition to your MIG 140.
