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 140 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 140 runs off a 120V power outlet which means it’s compatible with your standard indoor power outlet, however, this will not work with generators on remote sites. 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 center 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 light weight, 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.

Features

  • Auto-set automatically sets welder for mild steel.
  • Infinite voltage control for maximum flexibility.
  • Quick select drive roll
  • Drive system redesigned and is mounted at an angle to enable compatibility with 15ft MIG guns.
  • Thermal overload protection
  • Auto Spool gun detect which removed the need for a switch.
  • Includes 10 ft spool gun
  • Includes two gauge regulator
  • Door chart to help select settings if you wish to do it manually.

Advantages

  • Infinite Voltage control helps achieve maximum control and quality on different metal thicknesses.
  • The new design makes it easy to transport.
  • Super easy for beginners to use because of the new Auto-set feature.
  • Very smooth spatter-free starting capability which makes the weld cleaner.
  • Quick-select further reduces setup time, making it the fastest setup time for a 140A welder.
  • 120V input power means you can use it at home.

Disadvantages

  • Cannot be used for industrial projects with thicker metals.
  • Power input is not compatible with generators.
  • 5ft power cord could be longer.
