Welding continues to be a popular industry around the world; the size of the global welding products market was estimated at $14.49 Billion in 2019 alone. The Bureau of Labor also saw growth in welder employment, with industry figures increasing at least 3% from 2019 to 2029.
Whether you’re a home welder or a professional, you need the right device. The Hobart 140 and the Miller 141 are two great devices for DIY welding, but which one is better for MIG welding?
In this review, I’m comparing the Hobart 140 and the Miller 141 to find the superior welder. I’ll go through the similarities and differences between these two welders, then reveal which one is the better choice.
Hobart 140 Review
The Hobart 140 was designed to be the most compact flux/MIG welder in Hobart’s products. It is known for its incredible functionality at a reasonable price point.
The Hobart 140 has multiple safety features to protect users while welding. It has an overload system that can be reset, as well as a safety mechanism that keeps the wire safe until the welding gun trigger is pulled.
Apart from safety features, the Hobart 140 has a user-controlled power cooling system. This can either be manually turned on by the user automatically turned on when the welder needs to be cooled, helping to reduce noise and energy waste while welding.
It also has a sturdy build made of strong, quality steel, despite its lightweight gun and cable. This is a good combination that makes it both durable and easy to wield.
Because it only has a range of 25 to 140 A, its heat and power are limited. This makes it best for welding mild steel and thinner metals. But despite this lower power, it consistently produces strong, clean arcs, smooth welds, and precise penetration.
This welder is easy to use and set up. In just a few minutes, you can set the welder to your desired thickness and wire speed. The Hobart 140 welds materials with a maximum thickness of 24 ga. up to ¼ in. in a single pass, so its application is limited to home and auto projects that use thinner metals.
The Hobart 140 runs on standard household power sources due to its voltage range. Some users have reported trying to use it with generators to varying success.
If you’re looking for a welder for industrial use, you’re better off looking elsewhere. However, it’s a solid choice for indoor projects and home applications.
Miller Millermatic 141 Review
The Miller Millermatic 141 is manufactured by Miller Electric. It is a versatile welder, designed for a wide range of DIY projects.
One of the best things about the Miller 141 is its usability. It has an auto-set control feature that allows you to pick the material thickness and the wire diameter from the welder’s front. This makes the set-up very easy, even for first-time welders.
All you have to do is follow the settings chart to adjust for use. Choose your material type, gas type, wire diameter, and material thickness. Once you’ve finalized your settings, you’re ready to start welding. This fuss-free set-up will save many amateur welders a lot of frustration.
The Miller 141 is a versatile welder that allows you to weld aluminum at a range of 14 gauge to 18 gauge. It also welds steel and stainless steel ranging from 24 gauge to 3/16 inch. Because it comes with a thermal load protection sensor, you will be alerted when it has overloaded beyond a set time.
The Miller 141 welds very smoothly and has little to no sputter. It also has infinite voltage control, improving control and welding quality. Its 120 V supply means both hobbyists and professionals can make use of this sturdy welder at home.
Overall, it is a top choice for welding because of the easy user experience and great weld control.
Similarities Between The Hobart 140 And The Miller 141
The Hobart 140 and the Miller 141 have several similarities. Both the Hobart 140 and the Miller 141 have the same duty cycle of 20% at 90 amps, so they have the same requirements for cooldown and continuous use.
They are also both suited for connection to a standard household power supply because of their input voltage. The Hobart 140 has an input voltage of 115 V, while the Miller 141 has an input voltage of 120 V.
Both are equipped to handle flux core and MIG processes with similar inclusions. Both the Hobart 140 and the Miller 141 come with a gas valve, gas hose, and dual gauge regulator, as well as a 10 ft. MIG gun and 10-ft. work cable and clamp.
Differences Between The Hobart 140 vs The Miller 141
The Hobart 140 comes with an overload system that can reset itself. This system also has a mechanism that makes the wire safe until you pull the trigger of the welding gun. On the other hand, the Miller 141 does not have a similar feature.
However, there are several features that the Miller 141 has that the Hobart 140 does not. The Miller 141 has a quick-select drive roll and drive system that makes it compatible with MIG guns of 15 feet and has a double gauge regulator and manual door chart. It even has auto spool gun detection, so there’s no need to have a switch with your spool gun.
The Miller 141 also has a much shorter power cord than the Hobart 140. The Miller 141’s power cord measures 6.5 ft, compared to the 10 ft. power cord included in the Hobart 140. This length difference will limit the usability of the Miller 141 for outdoor projects.
There is also a slight weight difference between these two welders. While both have a sturdy steel build, the Miller 141 weighs 51 pounds. This is slightly lighter than the Hobart 140, which weighs 57 pounds. This will affect portability and where you can take your welder.
The Miller 141 has two handle slots apart from the handle on top, so users can attach extra handles, while the Hobart 140 does not have extra slots. Please note that despite this added portability, both welders should be transported using a wheeled cart because of their weight.
Both the Hobart 140 and the Miller 141 are great choices for a home welder. They are both very portable, suited for household projects, and are easy to use for amateurs and professionals alike. However, I recommend the Miller 141 by a slight margin.
The Miller 141 is much lighter than the Hobart 140. While it doesn’t have as many safety features as the Hobart 140, it is easier to set up and has a wealth of features for control and usability that the Hobart 140 does not have. This is why I would choose the Miller 141 as my top pick, whether you’re just learning to weld or you’re a seasoned hobbyist looking for a quality welder.
