YesWelder Mig-250 Pro Aluminum Mig Welder Review 2022

No matter where you are on the welding spectrum, you have many options to choose from. A welding product should be thoroughly researched and chosen based on its ability to meet your needs.

In spite of their affordable price tags, welding machines such as the Yeswelder are relatively unknown. The machine can be used both in a garage and in a commercial setting just as easily as it can be used elsewhere. In general, this kind of welding machine can handle welding jobs, but it is not suitable for jobs requiring high-frequency starting.

Its power output is 250A and its duty cycle is 60%. A piece of this equipment is capable of handling heavy welding jobs due to its power. The welding machine can also do flux core and stick welding in addition to MIG and TIG. The two primary applications of MIG are flux core welding and MIG welding. The robot can be used for Stick welding as well as TIG welding as well as lifting arc TIG.

MIG-250 Pro’s power, flexibility, and affordability make it the ideal tool for industrial, commercial, and automotive repair shops with a need for 250A of power, as well as do-it-yourselfers.

Due to the lightweight of just 34 pounds, this machine is extremely portable despite being powerful, making it easy to transport from one work site to another.

YesWelders MIG-250 Pro – Brief

YesWelders MIG-250 Pro – Buying Guide

There is NO regulator

There must be some “cutting corners” involved in low-priced welding. Correct? Yeswelder seems to assume you have an existing regulator because they excluded one.

The MIG-250 Pro does not come with a regulator, which might be an issue if you need one. When buying a new regulator, remember to include it in your purchase.

Aluminum Welding

For MIG welding aluminum, a Teflon liner is used. Good to hear that, then. It’s a good thing you should know, so why list it here? The answer to your question is that MIG welding is the only way to weld aluminum. For aluminum, TIG welding is not an option. A spool gun cannot be used with this machine. Only when welding aluminum should MIG be used.

Metric Units

The welder is manufactured offshore, as you might expect based on the price. But that means that some things on this welder are listed in metric units, which is an unexpected inconvenience.

There’s nothing to be concerned about. For welders who hate to convert metric units to English units, this may not be a good choice. The issue can be resolved by US users, though it is a minor one. To assist with this task, many people made their own cheat sheets.

Instructions for Use

Another issue is that the manual is not the best one because the welder was made offshore.
It can be difficult to comprehend sentence fragments, paragraphs, or even whole sections when they are translated. You will be able to piece through the manual after reading it a few times.

The Setting Chart

A settings chart is not necessary with this welder, since it uses auto settings. Correct?

This is incorrect. With manual mode, a settings chart is obviously needed. Regardless of synergic mode, the amps you enter must also be based on the settings chart. You need to memorize the most commonly used settings by making a chart for every weld. As a result, Yeswelder includes an instruction manual along with a chart. Although the chart would be more useful if it were mounted on the interior of the wire compartment door, at least it is provided.

Beware, however. A little heat has been reported by most users when using the chart’s settings. Keeping that in mind may help you dial in your welding. As a result, users were pleased with the results with some tweaks (more on that later).

Add-ons and Consumables

  • Remember to pick up some consumables when you buy the MIG-250 Pro. Apart from a few tips, there are none included in the package.
  • Depending on what you intend to weld, you’ll need electrodes and maybe wire.
  • Additionally, you do not receive a TIG gun in the box, only a stick electrode holder.
  • Purchasing a torch separately is required for TIG welding. Welding in AC is not possible with this welder; DC will be required.
  • The MIG-250 Pro has several features that make it stand out.


You can weld thicker stock, like 1/2 inches, in a single pass with welding equipment that outputs 250A of heat. That will be useful for shops that deal with thicker stock sometimes like auto repair shops.

Welders in this price range usually have a maximum power of about 200A and a maximum lead size of 3/8 in. material. Thus, the Yeswelder MIG-250 Pro gives you more bang for your buck.

In addition, you have the option of welding thin stock at 30A, and some users say they have welded stock as thin as 24 ga. Using a unit like the MIG-250 Pro for thin stock might not be the best choice, but it is still attainable, and it is nice to have so much versatility in one welder.

Duty Cycle

Most people have probably thought, “So you’re going to get enough power with this welder,” when they first saw it. This will mean you’ll have to make sacrifices on the duty cycle.”

  • The MIG-250 Pro from Yeswelder is different. A duty cycle of 60% is observed at 250A. Rather than waiting around while the machine cools, you can spend more time welding.
  • It is a measure of how long the welder can run before it needs to cool down.
  • It is measured in percentages over ten minutes.

For instance, if a welding machine’s duty cycle is 60% @ 250A. The module can run for 6 minutes before requiring 4 minutes of cooling at 250A. Duty cycles increase when amps decrease.)

Synergistic Settings

Rather than turning knobs and pressing buttons on a control panel, welders want to weld. Synergetic settings (i.e. auto settings) allow you to quickly and easily set your welder for a specific weld method based on what the manufacturer recommends.

This feature is available on the MIG-250 Pro. With a few minutes of practice, setting your welder for any given job becomes quick and easy. It also allows you to adjust the settings to meet specific needs such as using C100 gas or adjusting the wire size.

For auto settings to work, you will need to set the wire size, welding process, and amps. You enter the voltage and wire feed speed (“WFS”) and the machine sets them for you automatically.

Voltage & WFS Trim

Synergic settings offer another nice feature in that they can be tweaked. You can adjust the machine’s automatic settings to get that perfect arc. Set the heat to the right level for your particular welding task.

It takes a little while to get the hang of the auto settings, but once you figure them out, you’ll be able to get each and every weld just right.

The presets also run hot for some users. However, if you find that an auto setting is too hot, you can adjust the settings to lower the temperature.

Adapting Inductances

In addition, you can adjust the inductance setting on the Yeswelder MIG-250 Pro. You can adjust the magnetic field around your welding if you are not familiar with this feature. The preset level can be tweaked by -10 to +10.

The fact that we can optimize the magnetic fields around our welds can reduce spatter on such an affordable unit, and we can get clean welds if the settings are set properly. MIG-260 Pro welders are typically equipped with this feature, but you can also find it on higher-end models.

2T And 4T Option

  • Most of the time, 2T is the default operating mode. Once you are done welding, release the trigger.
  • You also have the option of 4T with the MIG-250 Pro.
  • If you have to weld long lengths, the 4T option may be of interest since it negates holding the trigger once the welding begins.
  • When you are ready, pull the trigger and release it.
  • Once you are done pulling the trigger, release it again to stop the gun. Your trigger finger will thank you.


Last but not least, if you need power and a high duty cycle, this may be the best welder to buy.

You can find additional savings if you look around. If you use the link in this article to buy, you will be able to benefit from a special offer.

This welder appears on many “best of” lists, so it should come as no surprise. Price and features together grab the attention of a potential buyer.

With the price you pay, you get lots of power, plenty of work time, and you can also choose from a number of welding processes.

What We Like

  • Budget-friendly.
  • TIG, stick, and Flux-core welding capabilities.
  • Up to 1/2 inches of steel can be welded with 250A of power.
  • The duty cycle is 60% when the voltage is 220V.
  • A decent MIG torch that provides 250 watts of power.
  • MIG welding with aluminum wire and additional Teflon liner.
  • If necessary, synergic settings can be adjusted manually.
  • Synergy settings can be tweaked.
  • Controlling spatter with inductance adjustment.
  • An easy, safe way to change wires with a “cold” wire feed button.
  • Methods 2T and 4T.
  • Configuring C100 gas.

What We Don’t Like

  • Powered by 220V input only.
  • Converting metric units is sometimes necessary.
  • Housing partially obstructs changing wire rollers.
  • Rear power switch.
  • There is no regulator included.
  • TIG torches are available for purchase as a separate item.
  • Spool gun not accepted.
  • It’s a touch too hot in recommended settings.
  • Only one gas input.


The Yeswelder MIG-250 Pro multi-process welder might be a good fit if you only use 220V and want to weld thick stock. As well as having a 250A rating, this one also comes with a 60% duty cycle. Synergic or manual controls can be used to control all that power.

Moreover, aluminum can be MIG welded, and 2T and 4T operations are available. When you combine that with its versatility, allowing you to MIG, TIG, and stick weld, you have an interesting welder. In this case, you have a hard time ignoring an option at this price point.

Those who deal with a variety of stock thicknesses can take advantage of the MIG-250 Pro’s wide power output range. The settings can be fine-tuned easily according to your welding process. Even experienced welders are surprised at the quality of the welds you can produce when you have this degree of control.

The MIG-250 Pro’s power, flexibility, and pricing make it appealing to shops needing 250A of power, including auto shops, ranches and farms, maintenance shops, and DIYers.
