Lotos Technology is quite popular for making welders and cutters. They have been doing so with quality supplies since 2007. The company has a reputation for providing affordable cutters and welders for both industrial and individual consumers. It’s safe to assume that their products offer great services.

The MIG140 unit offers quality and performance which equals that of the commercial-grade. If you’ve been welding for a while now, this unit is a great choice to change to. This is especially if you deal with materials of larger sizes.

If you do DIY projects in your small workshop or garage, the welder is convenient to use. It’s also great for making small and simple repairs around the house. Even if you’re a professional shop owner, the MIG140 is a safe bet.

This welder offers you precision work with the two digital displayers. You can use them to change the speed of its wire feeder as well as the voltage to set it up for strong welds. Its multi-use feature allows you to weld mild steel, stainless steel and other materials made of metal.

It provides with very short setup time and ease of use, which is helpful especially if you are a beginner at welding. You get the changeable welding options to make the process either manual or automatic. Considering the value and the features, this machine is offering reliability.

The machine may not be the most powerful and largest welder you can get in the market; however, it provides great results for all the work it is capable of doing. It is capable of working both with and without using gas. Also, you are getting a highly versatile welder due to its flux core feature. 

  • Portable Design

The Lotos MIG140 weighs only at 54 pounds which is around twice the weight of other similar welders available in the market. Despite its weight, you can carry the welder from one place to another quite conveniently.

You get both industrial grade and durability with the welder without having to sacrifice the necessary transportability. It has a measurement of 9.6 in x 16 in x 14.5 in, making its size the same as the other units out there. Its size along with the quality of the interiors make it stand out from its cousins.

  • Control Panel

The welder has its control panel on the front, which is very user-friendly. You get a power switch at the panel’s top-left. Below the switch, you have the option to change the voltage as well as the speed to the wire feed. On the right, there are 2 digital displays showing the wire diameter and the arc voltage.

The company updated the welder with 2T/4T switches so that you can be versatile with your short and long period of work. While the 2T is great for short time manual work, the 4T provides automatic welding for longer periods so that you don’t have to keep holding the button.

The door chart in the machine helps you choose the correct settings for welding.

  • Power

The MIG140 needs 110V/120V input voltage to run, and you can get a 30-140A range for power output. Also, its duty cycle is 20 percent at ninety amps. In case you change to a different input voltage region, you will have to get an adapter to transform the current to 110V/120V.

For the best use of the welder, you will have to install a breaker of 30A. Ease of finding power sources for this machine is one of its best selling points.

  • Wire Feeder

Its wire feeder accepts a good range of different material sizes. In case of solid steel, the wire feeder will take wires from 0.025 to 0.030 inches. For flux-cores, the acceptable range increases from 0.030 to 0.035 inches of wire. The stock comes with 0.023 to 0.035 inches of wire packed inside.

Wire Feeder

There have some been reports of issues related to the wire feeder. Test your welder when it arrives to claim the guarantee just in case you run into any problem. Also, remember to test out all the other features as well to make sure your machine doesn’t face any issues while working.

The welder allows stainless steel and regular steel while having its flux-cored and MIG welding. You can weld aluminum. However, the package doesn’t come with any spool gun, and you have to purchase one yourself.

  • Accessories

A MIG torch, welding mask, Argon gas regulator, ground cable, gas hose, and two 0.023-0.035in wire spools are included in the welder package. Also, you can purchase a warranty extension, if you wish to do so.

The best thing about this welder is that the manufacturer offers a 30-day money back guarantee if the performance doesn’t satisfy you.
