Whether you’re new to welding or work as a professional, Eastwood’s MP140i is an ideal all-in-one welder. This multi-process welder lets you work the way you want – MIG, TIG, flux-core, or stick. Capable of output up to 140 Amps, it’s flexible enough to switch from welding thin sheet metal to structural steel up to 3/16-in. thick. With the addition of the optional spool gun, it can even weld aluminum.
User-friendly features include a spot-weld timer for hanging panels, infinitely adjustable knobs for precise tuning, and a digital display to give you accurate readings. It’s equipped with three pro-grade torches plus common consumables and accessories.
The MP140i’s IGBT inverter technology produces the most stable arc possible while saving weight. It weighs in at just 34-lbs and operates on a standard 120V power output, meaning you can take it anywhere a welding job is needed.
And it’s all backed up by Eastwood’s 3-year warranty and lifetime tech support.

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.

Questions & Answers
I want to purchase a mig but also want to learn to tig weld roll cages. In the specifications it looks as though all 3 of your multi process welders handle the thickness but which one would be best suited the MP140i - MP200i - MP250 Multi Process Welder ?
Your selection of the welder will depend on the thickness you are looking to weld.
Date published: 2020-09-24
Does this welder come with over and under voltage protection built into the welder design? If not what does it come with to avoid dirty power problems?
Our welders do have under and over voltage protection built in.
Date published: 2020-09-16
My machine stops in the middle of welding and shows an error code (O LOAD) while i continue to hold the trigger. Im assuming it means overload. Any suggestions what is causing this?
We would refer to you contact our customers service department for further testing.

Is the Tig torch water cooled ? And how well does the optional spool gun work with this welder ?
This unit does not have a water cooled TIG torch and the optional spool gun works very well for aluminum welding.
Date published: 2020-07-29
Does the tig have high frequency start ?
This unit is not a high frequency start. You'll need to scratch start this unit.
Date published: 2020-07-29
Can I run this unit at full power with a 30 amp breaker? Also, why can this not TIG aluminum?
This unit only requires a 20 amp breaker on 120v service. A 30 amps breaker would also work as the unit draws less than that. As for the TIG welding this is a DC TIG welder which can only weld Steel and Stainless steel. TIG aluminum needs AC welding.
Date published: 2020-12-23
Can this run on 220 or 110
Our Elite 140i is a 110v only machine. If you wish to have the option then our Elite 200I is the machine to look at.

do you sell a foot pedal attachment for tig on this welder???
Unfortunately this unit does not have a foot pedal option.
Date published: 2020-05-07
Does this welder still use the 75%/25% gas mix? And can it tig aluminum at all?
For Mig you will want to use the 75/25 mix. However, any TIG needs 100% Argon. This matching is only able to weld aluminum with a spool gun.
Date published: 2020-07-29
With the correct gas can i TIG aluminum
This unit can't tig aluminum, however, you can weld aluminum with a spool gun.

Does this unit will operate 15 amps breaker?
This requires a 20 amp 120v breaker minimum.
Date published: 2020-12-23
Does this welder come with a foot pedal for tig welding?
Unfortunately, this machine along with all of our MP units do not have a foot pedal option.

Does this unit only weld up to 3/16" steel, or is that a typo? If so, I guess I need to look for something different, unfortunately.
Yes, as stated this unit will weld up to a max thickness of 3/16". You can achieve thicker capacities by utilizing flux wire through the MIG function- but this would be the only alternative for this unit.

Can this welder operate off a generator and what size is required?
This unit will work with a minimum of a 5000- watt generator.
Date published: 2020-12-23

Good day, I just placed order for a 175 mig welder with spool gun (item # 12012) I have been running the unsanctioned machines for decades off an HF 8700/7500w generator with reasonably good performance. How well does the MP140i run 4043 x .030 on gen
This machine will work off of a minimum of a 5000- watt generator.
Date published: 2020-09-13
I have a 5000 watt generator can I use this welder if not do I have any thatdo
Yes, this machine will run successfully off of a minimum of a 5000-watt generator.
Date published: 2020-01-28
Some answers seem to say you need a 7000 watt generator to run this welder and others say you can run it with a 2400 watt generator. Which is true and if the latter, to what degree can you utilize its capacity with a 3000 watt generator?
We apologize for the confusion. This unit will run successfully off of a minimum of a 5000-watt generator.

What size is the dinse connector for the ground cable?
This machine utilizes a 10-25 Dinse connection.
Date published: 2020-09-13
Can this welder use a foot pedal for Tig or is it strictly starch start?
This unit is strictly scratch start.
Date published: 2020-01-28
I have a Vulcan VA-SPLG 160A aluminum spool gun. Will I be able to use this with the MP140i or will I need to rewire the spool gun to welder connector?
Unfortunately, we can not guarantee compatibility with any item we do not offer. This unit was designed with a spool gun that we offer specifically for this machine: https://www.eastwood.com/eastwood-mp140i-mp200i-spool-gun.html
Date published: 2020-01-22
what kind off gas do you use for tig i got a tank of argon for mig can i use that
Tig welding requires 100% Argon. Mig welding requires a mixture of 75% Argon and 25% co2 for proper penetration.
Date published: 2020-09-13
How heavy of a mig wire spool can I use exp:5lb 10lb how much can it handle
The MP140I can handle the 8" roll, generally 11 pounds.

So does this run off 110v outlets or 120v outlets? The videos and descriptions have said mixed things. Thank you :)
These will run both off of 110v and 120v outlets.
Date published: 2020-01-22
Do the knobs turn freely or do they click at each setting?
The knobs turn freely, they are not indexed, that way you can dial in your wire speed and temp very precisely.
