Last updated:

Small shops and welding enthusiasts may start with a 120V welder. But if your welding hobby or small business is more serious, you need better power and the ability to weld thicker stock.

That means moving up to 240V on a budget without losing the ability to weld thinner stock.

The Eastwood MIG 180 fills those needs nicely. This recently introduced, affordable machine will eventually replace the popular Eastwood MIG 175.

It keeps the best of the old MIG 175 while adding some valuable improvements, establishing the new Eastwood MIG 180 as an exciting option.

But because it is so new, you may not know much about this dual voltage MIG welder. Fret not; I’ve done the research and summarized all you need to know below.

Eastwood MIG 180 vs MIG 175 – What’s Changed?

The most significant change has come from the newer IGBT inverter-based tech, which replaces the old transformers. This also lowered the weight and made the unit a bit more compact.

Read: Inverters vs Transformers

With a tad more power, the MIG 180 now also runs on 120V or 240V input power. Plus, it includes a better duty cycle.

A metal wire housing mechanism adds durability, and you now have more trigger control options. Plus, the convenience features (e.g., spool gun switch on the control panel, toolless polarity changes) make the welder easier to use.

The significant changes between the MIG 175 and MIG 180 are summarized in the table below.

What to Know Before Buying the Eastwood MIG 180

Stock Thickness

Eastwood recommends this welder for applications like auto restoration and metal fabrication work. But if you have the budget and expect to work with stock thicker than 5/16 inch regularly, you may want to spend the extra for a more powerful welder that can handle thicker material.


You receive enough consumables in the box to get started (a 2 lb. roll of wire, 3 contact tips, and 1 nozzle). But if you expect to do some serious welding, you need more than this.

So, consider adding any necessary consumables to your initial order. Also, don’t forget to get a bottle of gas.

MIG Welding Aluminum

The included chart includes settings for MIG welding of aluminum from 17 ga. to 1/8 inch. That may lead you to try and MIG weld aluminum.

But, if you plan on working with aluminum often, just go for the spool gun package. Avoiding the tangled wire and birdnesting is worth it.

Things that make the Eastwood MIG 180 Great


The MIG 180 uses IGBT inverter technology, and it is much lighter because of it. IGBT inverters also produce a smooth, user-friendly arc. Plus, this welder can also run on a generator (10 KW minimum).

Dual Power Input

The old MIG 175 ran on 240V, but the updated MIG 180 can run on 120V or 240V. More options to plug in mean you have greater freedom in how and where you use your welder.


The MIG 180 weighs in at just over 25 lbs., a fraction of the weight of welders running with transformers.

If you carry or move your welder often, this welder makes the task easy. It even includes a sleek hand incorporated into the top of the unit.

Tack Mode

Frequent tack welding beats on a welder’s components and can be hard on the operator, too. Plus, consistently getting the right timing can be a challenge, which results in varied tack weld quality.

But with the included “timed” tack mode, the 180 lets you make consistent tacks. You get a consistent 1/2 second long tack weld with less effort and fewer demands on the welder’s internals.

2T or 4T Modes

Long welds tire your trigger finger, and your hand can get hot with standard 2T operation.

But with 4T, you pull then release the trigger to start welding. You can then move your hand back and make the weld.

To stop, you pull and rerelease the trigger.

This feature is not expected on welders at this price point. But Eastwood included 4T on the MIG 180, and it helps anyone who makes long welds, novice or expert.

You can read more on the details of the 2T and 4T feature here.

Control Panel

The control panel provides a clean, easy-to-use setup. Two knobs and two blister buttons occupy the front panel. That is it for controls.

The knobs offer infinite control of the WFS and voltage. Tweakers love the ability to nudge their settings for the perfect arc without being limited by taps. 

But novice welders will also love the simplicity in setting just two knobs as indicated on the included settings chart. It does not get much easier.

The first of the two buttons set the MIG 180 for a spool gun or MIG torch. The second button selects the tack, 2T, or 4T mode of operation.

Indicator Lights

The old MIG 175 came with a lighted power switch to let you know when it was on. It also had an overload light to let you know when the unit overheated.

The MIG 180 retains these lights, although the lighted power switch is now on the back of the unit. To let you know the power is on, the control panel now has a separate, green power-on light.

It also has a high temp light on the panel that turns red when you exceed the duty cycle.

The blister buttons also use indicator lights to identify your selection. This is handy since you do not need to open the wire compartment to see your selections. You can tell from a distance, at a glance.


The MIG 180 price compares well to other dual voltage welders with the same performance.

In fact, it costs less and has more features. If you think that is an exaggeration, check the prices yourself.

The reasonable cost makes this welder accessible to a wider audience.

Optional Spool Gun Bundle

You were not able to buy the MIG 175 without the spool gun which added a little cost to the package.

Now, Eastwood offers the MIG 180 with or without a spool gun. This brings down the cost of the welder if you do not need to weld aluminum.

Buying the bundle does save you some money. In fact, some competing welders without the spool gun cost more than this bundle.

If you already own the MIG 175, then good news – the spool gun is compatible with the MIG 180.

Tweco Style Torch

The MIG 180 includes a Tweco-style torch. So, you can find parts just about anywhere.

That includes big-box stores, which come in handy after hours, or if it is difficult for you to locate a local welding supply store.

Toolless Polarity Changes

Eastwood made switching polarity for gasless welds on the MIG 180 a snap, or more precisely, a twist.

Simply unplug the gun lead and ground cable on the front of the machine, and swap them in the negative and positive sockets. 

No hard-to-access bolts and no tools. Plus, you can see with a glance at the front of the machine how your polarity is set—no need to open the wire compartment door.

Things That Can Still Be Improved


Eastwood supplies leads less than 10 feet on the MIG 180. This will likely annoy some, and a few users may even decide to replace or modify the leads.

No one likes to be excluded from welding in hard-to-access places or anyplace else where longer leads are needed.

Wire Spools

The rolls of wire you can use are limited to 11 pounds. Some of the 8-inch rolls can weigh more than this, and the spool for the wire should be beefy enough to accept the heavier rolls.

Flux-cored Drive Roller

Eastwood recommends using the smallest groove on the supplied roller for flux-cored wire. But this roller contains smooth grooves for solid wire. These are not typically used for softer, flux-cored wire.

No knurled roller is offered for the MIG 180 at this time (confirmed with Eastwood). I suspect this may be an issue for those who weld outdoors or anywhere else where using a shielding gas will be difficult. Only time will tell if the use of the smallest, smooth groove is sufficient.

Alternatives in this Price Range

The MIG 180 bundle with the spool gun costs less than both the Hobart Handler 190 and the Handler 210 – without spool guns. But the performance is similar.

However, there are some important differences which are highlighted in the table below.

The MIG 180 builds on the success of the popular MIG 175. Like its predecessor, it meets the needs and budgets of serious welding enthusiasts, small auto restoration shops, and light metal fabricators. But now you can use 120V or 240V to power the new MIG 180. This new model even made it onto our list of best-value MIG welders you can buy overall. 

The most noticeable change made by Eastwood, they switched from transformers to IGBT inverter tech to run the welder. This move improved the duty cycle. Plus, replacing the transformers has dramatically reduced the weight. So, the MIG 180 is easy to move and transport.

For added durability, a new metal wire drive housing was added. But Eastwood included new features that make this welder easy and convenient to use, too. For example, they moved the spool gun switch and toolless polarity changes to the front of the machine.

When you factor in the price, you realize the value of all the features packed into this new welder. If you run a small shop that does not weld overly thick stock, the upgraded Eastwood MIG 180 should be on your list of welders to consider if you are in the market.

  1. Thanks Jeff. I have been curious about this welder since Eastwood introduced it and after reading your review I think it’s a good fit for my equipment repair shop.

  2. Looking at the website, it looks like they have added the knurled roller for flux wire or it will be available soon
