Power 140 MP vs. LE31MP
The table mentioned above should give some insight into the two welders. Still, there’s more to know while checking your ultimate purchase. Therefore, explore a brief overview of the options separately.
Lincoln Power 140 MP Overview
The multi-process unit is an excellent purchase for standard welding applications. It has everything to get the job done perfectly. The lightweight and portable design only require a 120V power connection.
With MIG, TIG, Stick, and Flux-Cored welding, you’ll receive amusing versatility. But the 140MP features DC TIG applications only. There’s a brass-to-brass gun connection to have further mechanical conductivity.
An enclosed multi-stage gearbox ensures sufficient torque on the output. Also, the cast aluminum body keeps the device intact against outdoor elements. And you’re to enjoy a quiet operation with this one.
Almost everything necessary for the process is present in the box. You can even choose the Power MIG 140 MP TIG One-Pak option. It comes with a PTA-9 TIG Torch and a matching foot pedal for the action.
Pros and Cons
Lincoln Electric LE31MP Overview
LE31MP is more like a direct alternative to the Power 140 MP welder. It’s a versatile and multi-process welder for everyday jobs. The 120V power rating makes the device ideal for home and commercial use.
You can switch between the TIG, MIG, Stick, or Flux-Cored process anytime. Likewise, LE31MP allows only DC TIG welding. However, a stellar performance from either one is sure to help you with the tasks.
The assembly is easy to set up and put into use. That makes the welder a great purchase for beginners, pros, and trainees alike. But the device is more suitable for small-scale projects rather than heavy ones.
A large color display should have your attention right away. It isn’t exactly the best feature with slight downsides. But you can get through the necessary assistance related to its operation without any clutter.
Pros and Cons
Lincoln 140 MP vs. LE 31 MP: Similarities
The tabulated comparison shows almost no visible difference between the two. Not to mention, not much distinction is available for the devices. Hence, take a look at the essential similarities.
Even the weight and dimensions are entirely identical to one another. Compact size and its limited weight contribute to the high portability. You can carry either one with optimum comfort.
MIG, DC TIG, Stick, and Flux-Cored welding are available on both machines. You’re free to set the right welding mode. Also, the overall outcome of your welding task remains almost the same.
Everything necessary is present inside the package for a quick setup. A simple yet supportive interface makes both designs user-friendly. Any beginner/trainee can easily unlock their full potential.
Superb performance for the value prevails for either one. Steel welding on small projects delivers maximized performance. Even the limited welds on aluminum appear great on completion.
Home, autobody, shop, farm, even hobby – both ones hold it right. However, neither one is good for extensive/frequent use. So, it’s better to avoid getting the welders for any heavy processing.
Lincoln 140 MP vs. LE 31 MP: Differences
People often fail to recognize any difference in 140 MP from LE31MP and vice versa. But there are mere technical differences between the two. Check out the usable discrepancies to make the purchase.
Reliable wire feeding is impossible to achieve without the right spool. And 140 MP seems to have only one spool of 8” size. Meanwhile, LE31MP lets you utilize a 4” or an 8” sized spool as per your needs.
Even the included gears are almost similar to each other. But 140 MP allows you to choose a simpler package for TIG welding only. But there’s no such option available with LE31MP’s purchase.
Market price varies from time to time, depending on many conditions. However, LE31MP is somewhat cheaper than 140 MP. No wonder why the former is more popular as one full package.
Frequently Asked Questions
