Considering the Millermatic 255? Here's What You Need to Know Before You Buy

Are you on the hunt for a MIG welder that not only meets but exceeds your welding expectations? Look no further than the Millermatic 255 Pulsed MIG Welder. Released in January 2019, this powerhouse from Miller is turning heads in the welding community. At Baker's, we've unboxed and tested the Millermatic 255, and we're here to give you the lowdown on why it might just be the welding machine you've been dreaming of.

1. Fast Tack Welding Mode: Boosting Productivity

Let's start with a game-changer – the Fast Tack Welding Mode. If you're tired of the delay caused by run-in during tack welding, this feature is your new best friend. Stick tacks in place without the wait, significantly increasing your productivity. And here's the kicker – you can disable it if needed. It's about giving you control.

2. Crater Mode: Smoothing Out Welds

Say goodbye to unsightly craters at the end of your welds. The Millermatic 255 introduces Crater Mode, ensuring your welds end smoothly by adding a touch of extra wire. It's the attention to detail that sets Miller apart.

3. Auto-Set Welding Settings: Your Welding Guardian Angel

Building on the success of the Millermatic 252, the 255 takes auto-set modes to the next level. Modify your settings effortlessly for different material thicknesses and welding gases. With five programmable settings, you have a variety of options already dialed into your machine, making setup a breeze. This works in pulse mode as well!

4. Clear Screen for Welding Parameters: Intuitive and Efficient

Navigating through welding options is a joy with the Millermatic 255's simple dial and bright LCD display. Spend less time setting up and more time welding, thanks to its user-friendly interface.

5. Versatile and Portable Power: Where Strength Meets Mobility

Weld up to ½" aluminum, stainless steel, or mild steel with ease. The 255 offers power flexibility with 208 or 240-volt options. Need lower heat input on thin metals? Switch to pulsed MIG mode for cleaner welds without burn-through.

Despite packing all this power, the 255 weighs in at 84 pounds – 50 pounds lighter than its predecessor, the Millermatic 252. It's a testament to Miller's commitment to efficiency and portability.

6. Auto-Line Technology: Power Where You Need It

Don't let power limitations hold you back. The Auto-Line Technology ensures a seamless hookup to any single-phase input voltage (208–240V), ideal for jobs in less-than-ideal power environments.

7. MDX-250 MIG Gun with AccuLock S Consumables: Precision Performance

Precision matters, and the Millermatic 255 delivers with the MDX-250 MIG gun. AccuLock liner ensures flawless wire feed, and the new rubber overmold and ball-and-socket handle design improve grip and reduce fatigue.

8. EZ-Latch Running Gear: Effortless Portability

Loading and unloading your welding machine is now a breeze with the optional EZ-Latch running gear. No need for a lift truck – simply loosen the latch retaining knob and rotate latches for easy portability.

9. Generator Compatibility: Power Anywhere, Anytime

Weld on the go with confidence. The Millermatic 255 can operate at full output with generators providing 12,000 Watts (12K) or higher, making it versatile for various job settings.

10. Spoolgun and Push-Pull Gun Compatible

You can directly connect a spoolgun or push-pull gun for MIG welding aluminum to the Millermatic 255. Check out our review video with Andrew who walks us through what using a push-pull gun with the 255 looks like and how the pulse function works on this machine.
