What You Need To Know Before Purchasing A MIG-205 DS

There are no consumables

Yeswelder kept the box’s consumables to a minimum. You receive no wire, no stick electrodes, and only a few tips (one 0.030 and one 0.035). Consumables must be purchased individually.

The good news is that they sell electrodes and welding wire directly at a reasonable price.

TIG (Teflon Inert Gas) Welding

While this machine is DC TIG capable, it does not have a TIG torch. Therefore, you must acquire one in addition to the welder if you intend to use a DC TIG with it.

Additionally, the YesWelder MIG-205 DS utilises a lift TIG method only. This welder is not equipped with a foot pedal.

You Will Require Your Regulator.

Another component that you must provide on your own is the gas regulator. While a gas pipe is provided, the regulator is not. They have their own branded regulator, which is rather effective.

Aluminum Cannot Be Welded

Because this welder is not capable of AC TIG welding, you may believe you may MIG weld metal if necessary. Regrettably, this machine does not come equipped with a spool gun. However, if you know what you’re doing, running solid aluminium wire via the wire feed mechanism is feasible.

In conclusion, you should avoid purchasing this welder if you are new to welding aluminium. However, with some trial and error, you can learn to run aluminium wire through the wire feed system if you are patient and willing to cope with an occasional difficulty.

User Manual OR Guideline

Expect little from the user handbook. It is brief, badly written, and includes significantly less information than a novice welder will require.

Additionally, the chart typically written on the inside of the wire drive door is missing, making the welder more difficult to use, even with presets loaded into the device.

You should budget some time on the internet to learn how to set up and operate your new welder. The good thing is that this welder is rather popular, which means there are several videos to view. Additionally, you may download charts created by other users.

Additionally, many customers find that the settings for comparable Miller welders serve as an excellent starting point for their own.

Metric Units

When entering the thickness of your stock, it must be in millimetres. There is no metric to inch conversion table included. As a result, you will have to convert independently.


The leads connect to the device through the shorter “Euro” dense connectors. They operate quite well but are somewhat shorter. If you have some older leads with a slightly longer connection, they will not fit the MIG-205DS from YesWelder.

If you need to add extensions or replace the ground or light in the future, just purchase the Euro, shorter dinse connection (dinse 35-50).

Latest Inverter Technology

Due to the utilisation of inverter technology, this machine is lightweight and small. Additionally, it provides 200A of power output from a small welder at a 60% duty cycle. While it is theoretically a superior feature, there is one caveat you should be aware of.

While inverter technology is effective, some welders assert that only time will tell if it is lasting. Thus far, the answer appears to be affirmative; however, to be fair, this technology is more recent than certain earlier designs (e.g. transformers).

The MIG-205DS Price’s Best Features

At less than half the price of some rival welders, this is an excellent deal. However, do not forget to include the missing gas regulator, consumables, and optional TIG torch/accessories.

Welder Synergic 

This machine automatically adjusts the wire feed speed (“WFS”) in response to the voltage/amps. However, you do have the option of adjusting the default WFS somewhat.

Additionally, the welder’s voltages and amps are set in proportion to one another. Volts and amps will vary in lockstep as you spin the dial (and the WFS is adjusted automatically).

This implies only one knob and a few buttons to fiddle with. The term “synergic” refers to this type of welder, making getting started simple and quick once you get the hang of it.

However, most users will discover that minor “fine-tuning” of the defaults improves the quality of their welds. Fortunately, the machine allows you to independently change the qualities. In general, most customers report that this device runs a little hot and that the voltages need to be adjusted somewhat lower.

Arc’s Qualities

The Yeswelder MIG-205DS’s arc is quite impressive. Indeed, with a little practice, you can also minimise splatter. Even experienced welders praise the arc quality of this equipment.

Additionally, this item allows you to alter the inductance setting to fine-tune the arc. This enables you to soften the arc or make it somewhat harsher as required for a specific weld.

Wire Feed System

The wire feed system is entirely made of metal. (Some of the feed components on many budget level welders are plastic.) Yeswelder appears to recognise the critical nature of the wire feed system and has included some quality into their own.

Ground Clamp

The clamp is sturdy, and the jaws are connected by a braided wire. This is not a feature available on the majority of cheap welders.

TIG Lift

Another pleasant surprise on the MIG-205DS is the lift TIG start, which dazzles even the most seasoned welders. It does not adhere but is fairly smooth, allowing for better welding. This kind of performance is uncommon on low-cost devices.

MIG 2T and 4T

It is a personal taste, and the majority just employ the 2T technique. However, the YesWelder MIG-205DS allows for using a 4T MIG technique.

For those unfamiliar with 2T welding, you pull the trigger to initiate the process and release it to complete it. 4T refers to pulling the trigger to initiate the arc and then releasing it to continue welding. When you choose to pause, you pull and then release the trigger.

On paper, 4T appears to be complex. However, for lengthy welds, the trigger does not have to be held the entire time. More information regarding 2T vs 4T may be found here.


This supplied item weighs 33 pounds, whereas the “power supply” is just 22 pounds. Additionally, the case is compact enough to fold away during transit and features a top carry handle. The YesWelder MIG-205DS makes it simple to transport your multi-welder for individuals who carry their welder to work.


If you travel frequently, you are more likely to come across 110V outlets. No problem; this unit can operate on 110V or 220V if available.

Alternatively, if you want to add 220V to your store in the future, you can operate on 110V in the meantime. There are no restrictions, and a plug adaptor is supplied.

Welding with a SMAW

This welder is ideal for individuals who rely on stick welding in particular scenarios. It includes an electrode holder but not any rods.

Buttons for Configuration

Yeswelder offers a few pleasant features to assist you in getting started. One is the wire feed button, which automatically operates the wire feed mechanism. This enables regulated wire feeding via the lead to the pistol while the gas is turned off.

You can also do the same thing with gas. There is an independent gas “on” button. Again, this enables you to run gas through your system and precisely regulate the flow rate.

Comparing the MIG-205 DS and the MIG-250 Pro

If you’re contemplating the MIG-205DS, you may have seen that Yeswelder also offers a higher-end model, the MIG-250 Pro.

Given the little price difference, I felt it might be worthwhile to compare them briefly:

What The MIG-205DS’s Users Have To Say

In general, welders make a few remarks when they utilise this equipment. “The Yeswelder MIG-205DS is an excellent deal, especially at $500.” The high duty cycle is unmatched in its class.”

Additionally, the terms “surprising” and “easily utilised” are frequently used to characterise the welding experience. Additionally, people frequently state, “I like this small gadget.”

One commonly repeated recommendation is “the welder settings for the auto set will be too hot; I would start by dialling it down a little.” Fortunately, the MIG-205DS’s settings allow for this.

Another excellent tip: “consider purchasing the welding wire from Yeswelder concurrently, as it is reasonably priced.” Consumables are not included in the box, however, Yeswelder makes it simple to add them to your order at a reasonable price when purchased straight from them.


For a modest price, the Yeswelder MIG-205DS offers MIG, flux core, TIG, and Stick welding capabilities. It operates on 110V or 220V, has a 60% duty cycle at 220A, and the inverter technology results in a small, lightweight, easy carry machine.

Additionally, Yeswelder installed a useful control panel shielded by a dust cover. A carry handle, a specific setting for pure CO2, and an inductance adjustment are included. Thus, despite being a “cheap” welder, this machine includes a plethora of helpful functions.

You get a lot for your money, and the performance allows you to enjoy welding with this equipment. More importantly, with experience, you can generate strong welds and understand which settings work best.

This equipment is cheap for beginner welders or those on a tight budget, and it adds a variety of additional possibilities to a small operation. Alternatively, if you’re looking for a low-cost backup welder, the MIG-205DS is an excellent choice.
