Usability
One of the best things about this welder is the new auto-set control. A blue light will show up when auto-set is activated and all you have to do is select the wire diameter and material thickness on the front of the machine and you can immediately start welding. This is a great way to save time and help beginners set it up. If you prefer to set things up manually, you can still do this by using the chart on the inside of the door and selecting the controls from the 10 wire feed speed settings and infinite voltage control.
With the Millermatic 141 you can weld steel and stainless steel from 24 gauge to 3/16 inch and aluminum from 14 gauge to 18 gauge. You’ll only reach full 3/16 inch with flux cored so it’s not quite as powerful as other 140 welders but it does provide great quality and user experience.
Power
The Millermatic 141 has an amperage range which extends from 30A to 140A. The duty cycle of this is 20% at 90A and 100% at 40A, which means from 2 minutes of welding time at 90A it will need an 8 minute cooldown period. This welder is fitted with thermal overload protection to stop you from exceeding this time.
The Miller Millermatic 141 runs off a 120V power outlet which means it’s compatible with your standard indoor power outlet. One great feature of this machine which is the infinite voltage control settings to help ensure you get maximum control and the best quality weld.

Transport
The Millermatic 141 is designed to increase portability and weighs just 51 lbs, which is 9 lbs lighter than the Millermatic 140. This means it is much easier to lift and carry around. There is also a new design for the 141, in addition to the handle in the centre of the welder, there are two new handles added to the front and the rear, which further increases the ease of carrying the machine. 51 lbs is by no means a lightweight, so it might be better to still use a wheeled cart to transport the welder.
Price
This machine is a bit more expensive than the other 140 welders but it does have some additional features such as the auto-set feature and increased voltage control. If you’re on more of a budget I’d consider the handler 140 because it’s much more affordable. If you do decide to spend a bit more on the 141 it comes with Millers True Blue 3-year warranty to protect your investment.

Who Should Buy This?
The Miller Millermatic 141 is a great quality welder that has revolutionized the 140A class of welders with its new Auto-set feature and is the perfect tool for beginner welders looking to minimize setup times. If you’re a hobby welder using a garage or small workshop and don’t mind spending a bit more money to easily achieve those high-quality welds then this is a great choice.
This statement in the review is incorrect “this will not work with generators on remote sites.” The unit will in fact work fine on a generator. The minimum wattage required would be 4500 continuous.
Cheers Tank for pointing out that mistake. For anyone looking on advice about wattage required – try the calculation Volts x Amps = Watts.
Would really love to know where you got that “You’ll only reach full 3/16 inch with flux cored”, meaning the 141 won’t MiG weld 3/16 in a single pass.
Hi Daniel,
Like you said on the 211 review – It clearly states on the front of the 141 “Multiple passes required for solid wire” – In reference to 3/16″. The info from Miller is slightly misleading on the product specs sheet.
Often a better decision to go for a more powerful welder anyway, you can always turn it down but you can’t turn it a 140a up!
Thanks,
John
