How to Choose Between Miller's Multimatic and Millermatic Welders

How to Choose Between Miller's Multimatic and Millermatic Welders

Miller Electric has introduced some of the strongest competitors in the welding machine market with the Multimatic 255 and the ever reliable models of the Millermatic 255 MIG welder. These machines have been highly recommended by welding instructors, served as work horses on job sites, and powered many home welding projects, but how can a welder choose between machines that offer so many features and capabilities? 

We’ve done a deep dive into the specs for each machine to help you sort out what each one does best and how you can get the best price possible through rebates, bundles, and discounts on the Baker’s Gas and Welding website. Let’s dive in!

The Advantages of the Millermatic 255 MIG Welder

When welders are looking for a versatile, powerful, and easy to use MIG welder, the Millermatic 255 MIG welder is the machine you don’t want to miss. 

The Millermatic 255 delivers an all-in-one MIG welder with a brand new 7 inch LCD color screen, pulsed MIG welding, and the convenience of Auto-Set Elite’s pre-defined MIG welding settings. Save your most frequently used settings by programming them and storing them right in the machine.

Swap between 208 and 240 V input power and weld up to 1/2” aluminum, stainless and mild steel. The Millermatic’s inverter power allows single-phase input voltage hookup with no manual linking, smoothing out the arc for welding projects on unreliable power. 

There’s a wide variety of welding gun capabilities with push-pull MIG guns as well as spool guns. Each new gun is automatically detected so that it can be installed and ready to use with minimal downtime. 

Compared to the previous high capacity MIG welder from Miller, the Millermatic 252, the Millermatic 255 has been reduced to 84 pounds, which is 50% lighter, with a simple EZ-Latch cart capability that doesn’t require any additional tools. The Millermatic 255 is a MIG only unit. There is a Multiprocess 255 which we will dive into next.

Should You Go All In with the Miller Multimatic 255? 

The Miller Multimatic 255 multiprocess welder has the same pulse MIG functionality as the Millermatic 255. The biggest difference is the ability to Stick and TIG weld.  

The Multimatic 255 offers Pulsed MIG, Flux-cored, DC Stick, DC Lift-Arc TIG, and Pulsed TIG in an all-in-one 250 amp inverter welder.  You can also use it with push-pull MIG guns, allowing use of 12-inch spools.  

Long time Miller users will be glad to see the return of Auto-Set Elite, Miller’s time-saving feature that pre-defines weld settings according to the project type and skill level of each welder. You can use Auto-Set Elite with MIG, stick, DC TIG, and pulsed MIG welding processes. 

If you have a favorite welding setting or a particular process that comes up frequently in your shop, use Program mode to save these settings right on the machine. You can save up to four welding programs to ensure your welds are more consistent and easily set up when it’s time to strike your arc. 

Minimize your spatter, heat input, and metal distortion with pulsed MIG setting for thin materials. You’ll increase your range of MIG welding jobs, cut back on material costs, and save on grinding time for all kinds of projects. 

When comparing the Multimatic 255 to the Millermatic 255, the Multimatic has the same large screen but adds a full range of welding processes while delivering all of the same MIG welding features for a small difference in price.

The Only True Multiprocess Multimatic - Miller Multimatic 220 

Miller’s other game changer for many small welding shops and hobby welders with its full range of features, competitive price, simple display options, and portable weight: The Miller Multimatic 220 AC/DC Multiprocess Welder.

The Multimatic 220 offers true multiprocess capabilities with the possibility of AC TIG welding on top of MIG (GMAW), Flux-cored (FCAW), DC TIG (GTAW), Pulsed TIG (GTAW-P), and DC stick (SMAW). This lighter machine weighs in at 56 pounds for easy maneuvering around the shop or on your vehicle. 

You’ll have a solid, steady arc when welding at 120 or 240 Volt power, to weld steel and aluminum. On MIG you can handle of to ⅜” steel (24 gauge) and aluminum (18 gauge), on DC stick welding you can weld ⅜” 16 gauge steel, and on AC/DC TIG you’ll max out around ¼” 24 gauge steel and aluminum. 

This is the only Multimatic that you can AC TIG aluminum. See below chart for the small frame Miller machine comparison.

Hey Sean!

You can definitely still MIG weld aluminum, you would just need to get an Aluma-Pro push-pull gun. There are a couple different options with different price ranges, but it is going to provide a really awesome weld profile. You can even Pulse MIG aluminum with this gun!

Greg from Baker's

So with a miller 255 multi matic you cant tig aluminum and are the mig gun capable to weld aluminum or do you need a different gun
