Product Overview:


What The Pro's Think Of Eastwood Elite MP140i Multi Process Welder

Brian Kurtz - ASME & API Certified Welder

"The MP140i welds consistently with good arc stability just like the MP200i. It’d be great for the automotive guy welding patch panels, and lighter fabrication." Watch Video

Weird Beard

"This is an easy to use all in one welder that is compact in size. It plugs into a standard 110 volt wall outlet so it’s perfect for the diy home garage…it’s easy to get those professional looking welds we all like to achieve on our projects. Very easy to hook up. Capable of mig, tig and stick welding all in one machine. Very user friendly and super affordable. Far cheaper than buying 3 separate machines."

Auto Auction Rebuilds

"The Eastwood 140i is a perfect all-in-one welder for beginners like myself, or for the most seasoned pro! This is a must-have tool that every DIYer should have in their shop / garage. No need for big bulky machines that require 220 outlets anymore, as Eastwood has given us the perfect 3-in-1 mig, tig, and stick welder in a compact, easy to use, reliable machine!" Watch Video

Duty Cycle

The rated Duty cycle refers to the amount of welding that can be done within an amount of time. The Eastwood MP140i has a duty cycle of 30% at 90 Amps. It is easiest to look at your welding time in blocks of 10 Minutes and the Duty Cycle being a percentage of that 10 Minutes. If welding at 90 Amps with a 30% Duty Cycle, within a 10 Minute block of time you can weld for 3 Minutes with 7 Minutes of cooling for the Welder.

If the Duty Cycle is exceeded, the Welder will automatically shut off, however the fan will continue running to cool the components. When a safe temperature has been reached, the Welder will automatically switch the Welder output back on. To increase the duty cycle you can turn down the Voltage Output control.

Rated 5 out of 5 by from Great Entry Point Excellent entry point for a beginner. Ive only done MIG so far and it worked well. Ask me again in 1 year. I had an experienced welder help me with set up. Only suggestion would be, a 220 1phase addon. Maybe that would raise the price though.

Rated 5 out of 5 by from Eastwood MP 140i hit a home run!! After researching Multi Process Welders, I found the 140i covered everything I was looking for. I have used all the functions on it and found it to be very user friendly. Having some knowledge on the welding subject, it was not very difficult to get up and running immediately. The only issue I had was the instructional manual. It could have been a little more informative. But none the less, good job on the 140i Eastwood. I would recommend this Multi Process Welder to anyone from professional to amateur.

Rated 5 out of 5 by from Excellent welder for the price I was in the market for a new welder for my home garage to work on my project car and small fab work. It is definitely worth the money! Very quiet and has plenty of power to weld what I’m doing. I highly recommend this to anyone that doesn’t have the 230v outlet in their space.

Rated 5 out of 5 by from A heads up. It comes setup for .023, so you’ll either need argon/co2, or use the stick welding option. I first bought supplies locally and set it up for .030. Works good.

Rated 5 out of 5 by from Makes welding easy for a beginner. I'm new to welding and needed a mig welder for welding patch panels in the car I'm working on. I chose this Eastwood model because I liked the features such as infinite control knobs, digital display readout which is really nice, the spot welder function, and the multi process capability. You can't beat the price and the 3yr warranty is what made me decide on this machine vs others in the running. After a day of practice on scraps and watching a few videos on setup and welding tips, I was able to get repeatable, great spot welds on 22 ga sheet metal. I was even able to get butt welds without burn through. I'm welding an extension to the top shelf of my welding cart so this welder will fit nicely and not overhang off the top. Now I'm ready to actually start welding patch panels into the floor of my '39 Studebaker. Can't wait to get started. And with the multi process capability of this machine I will be able to learn some tig technique as well. One other thing. The machine runs nicely off of 110v and a 15amp breaker for the sheetmetal work. Might have to switch to a 20amp circuit for welding thicker material. We'll see.

Rated 5 out of 5 by from Love it! I bought this at the beginning of the year and have used both the stick and the mig functions of the machine. It works great and gets the job done. I will definitely be purchasing bigger and better machines from Eastwood in the future.

Rated 5 out of 5 by from Move from FCAW to MIG/TIG/Stick - My first Projects center around restoring 2 early 70's VWs - lots of sheet metal, lots of spot welds. Moving from a HF 125 machine with four heat ranges running flux core wire. My only "dislike": the MIG Spot Weld Kit does not fit even though most material on the website lead me to believe it was compatible with all Eastwood welders. Now for the "likes" (and the list is long!): spot weld timer makes repeatable spot/plug welds simple and consistent. The infinite adjustability of all the controls allow precise control of wires speed, power, and timer. The feed mechanism is smooth a predictable. The cables have plenty of length. Besides gas, all the start-up items for all three processes (except TIG filler rod) are included. Weighs less than my old machine with more capability. Bigger trigger on torch. Tried my first stick welds ever on railroad track section I have has anvil and successfully struck an arc and build up material with good penetration. Tried to get a pool going with TIG, but dipped the tungsten within 2 minutes - gonna keep trying (scratch start wasn't that hard). All in all, after 3 weeks the MP140i seems like it will meet almost all of my welding needs in the foreseeable future - glad it has a 3-years warranty, plus I got the 2yr extension. Yesterday when practicing, I stitched a 20ga butt weld that would have made Dave Kindig or Joe Martin proud - I credit the machine!.

Rated 5 out of 5 by from Love It I have not yet used it for TIG or MIG, but for wire feed, I love it. At first I found the trigger/spot timer is annoying but quickly got used to it. For the guy at home with average welding skills it is a really good machine

Rated 5 out of 5 by from Easy to set up and use. Purchased about a month ago and finally set it up and used it for the first time. Smooth operation and precise adjustments make for a great bead every time and does not skip a beat. Works as good as our Miller 250 at the garage I work at. Great welder for the first timer or experienced welder. Can not wait to try the tig torch and spool gun, Eastwood does not disappoint with this machine..

Rated 5 out of 5 by from Great welder for the money Have had this a week so far, and couldn’t be happier. Using it for a recall campaign on child anchors. The arc is super stable even when having to pull away to fit into tight spots, and the weeds are great. Primarily using for MIG on 2mm steel. Looking forward to using it for my own truck here soon.

Rated 5 out of 5 by from Great welder This is a very good welder, I have use this welder for a few projects, the.mig works perfectly, the Tig is very good for the beginner TIG welder to learn with, I tried the stick as well and was very impressed on how well this unit works oh, I would recommend this to family and friends it's an all-around good welder.

Rated 5 out of 5 by from Great little welder I bought one of these multi process MP40i, and I have to say it is a really nice welder. The Mig works great, smooth and easy operation. The scratch start TIG works great for quick little tig projects. I have not tried the Stick part of it yet. But I am very impressed with the welding it can do plugged in to a 110 outlet. I built a rack for my trailer yesterday with it and made for a quick and easy job. I was welding on 14 and 11 gauge mild steel and it worked great. I had to order it over the phone because I have different shipping and Billing addresses. But they worked it out and got it ordered and quickly shipped it out.
Date published: 2019-10-24
Rated 5 out of 5 by from More than pleased Bought a few weeks ago and love it it's a vast improvement above my Clark welder I had for 13 years. Love the welder and features works flawlessly and you guys at Eastwood offer best warranty on it. Can't wait to purchase more Eastwood products in the future.

Just want to check if it is normal that the wire feed starts 1-2 seconds after pressing the trigger, the gas starts immediately. My old Lincoln welder both started immediately. When I got this welder the mig torch had to be replaced because of a defective

Asked by: rtech2366
Both our Eastwood Elite MP140i and MP200i have a .5 second pre flow setting before wire starts feeding. this is to ensure clean shielding gas has made it through the torch and is providing proper coverage. The purpose of this is to eliminate any potential for contamination at the start of the weld. Many other welders in this price range do not have this capability. Many high end welders made by Lincoln and Miller have the ability to adjust this pre-flow setting. By having a fixed short pre flow we believe that we are able to provide a high quality weld, at a low price. It is also worth noting that while stich welding, if trigger is pulled multiple times quickly before the gas shuts off, the delay will not be present, this is due to the welder knowing that gas has been flowing, and the pre flow "Purge" is not needed. If you have any additional questions please feel free to contact Tech at 800-343-9353.
