Description

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.

Reviews

Rated 5 out of 5 by from MP140i Multi Process Welder. Right out of the box, I set it up for MIG with .023" wire, followed the chart settings for 16 gauge sheet metal, and BOOM!! Perfect welds on the first try. Perfect for the amateur hobbyist who is learning and doesn't yet possess the skill to wield 220v power. Can't wait to see what I can do with the TIG setup.

Rated 5 out of 5 by from Great little welder This machine is really light weight. So far it has handled everything I've used it on currently running .030 Flux wire. It came with plenty of spare contact tips but it would be nice if they were a variety of sizes.

Rated 5 out of 5 by from Excellent Welder! I bought this little guy last week and have put mainly the mig function to the test. It lays down a nice bead on sheet metal (AK rifle receivers). Bought this to replace a recent stolen old Clarke I had from decades ago and man I'm kinda happy someone stole my old one lol. This rig does it all with style. Mig torch is very sensitive and I like that, don't have to squeeze the crap out of it to get it going like my old one! I was a little hesitant buying a welder online, but this thing is built nicely. Time will tell about longevity, but it has a 3 yr warranty so that's a plus. I've heard great things about these. This is my first tig unit so I'll be toying with that function soon! Get one you will not regret it!

Rated 5 out of 5 by from Metal feeding gears made the choice easy. Great deal at a great price. Very fast shipping . Perfect in every way and very happy in every way but you cant tig aluminum. My other welder i cant tig aluminum. You have to but the $380.00 spool gun to MIG aluminum. 100% my fault. Everything on their part was perfect.

Rated 5 out of 5 by from Great portability! This is just what I needed to learn more about various types of welding. It’s been a long time and my skills are certainly lacking. The options of being able to stick weld and also use flux core when I need to grab it and take it somewhere for a quick repair is so easy due to its light weight. I also picked up a 75/25 bottle of gas for solid wire welding. I haven’t tried the Tig yet. Overall this is just a great little machine to have around your garage.

does the TIG torch have an on/off switch? I know it doesn't use a foot pedal, so wonder if once you turn on the machine, that the tungsten electrode is on and gas is flowing.

Asked by: Chris F
TIG welding with this unit is scratch start so no trigger is needed. Gas flow is controlled by a manual valve on the torch.

Which shield gas is recommended to solder car steel and aluminum and model MP140i can use them?, I am looking for the best priced welder that use Argon gas as shield (a request from a friend of mine). thanks.

Asked by: MarianoGil
The gas required depends on what you are welding and which process, this machine can MIG, TIG, and stick weld. I'll try to summarize: For MIG welding regular steel you want 75% Argon / 25% CO2 mixed gas. For MIG welding aluminum you need the optional spool gun, and 100% Argon. For all TIG welding use 100% Argon. If you have further questions our customer solutions team can go into further details 800-343-9353 or help@eastwood.com

Good morning. Are there any meaningful differences between the Elite MP140i and Titanium MP140 from Harbor Freight. Thank you

Asked by: Alex
The biggest difference with us would be you're getting a 3 year warranty instead of a mere 90 day one.

How do I calculate the amperage based on the voltage and wire speed settings? I am a little confused by the Duty Cycle Ratings.

Asked by: phreaktor
The duty cycle full details are printed on the bottom of the welder, but that label is a little confusing to look at if unfamiliar so here is what you're looking for: 30% @ 90A/18.5V MIG 30% @ 70A/22.8V Stick/TIG 60% @ 64A/17.2V MIG 60% @ 49A/22V Stick/TIG 100% @ 49A/16.5V MIG 100% @ 38A/21.5V Stick/TIG Note that these are under worst case conditions eg. extremely high ambient temperature, and will be higher in almost all real world scenarios.
