The Miller Multimatic 255 MIG/Pulsed MIG, Stick and Pulsed DC Tig Welder with running gear and TIG kit (951768) is designed for the light manufacturing and fabrication users who want a smaller, versatile workhorse that is easy to setup and easy to use. This 350-amp inverter welder can be integrated on running gear for easy movement around the work area or it can be quickly disconnected from the running gear enabling portability, making it easier to integrate into a work cell or work in confined spaces.

Easy-to-understand interface
7-inch color LCD display ensures proper machine setup and parameter selection, reducing setup time and increasing weld time.

Pulsed MIG welding delivers higher quality
Lower heat input for less distortion on thin materials, less spatter minimizes post weld grinding and rework allowing more welding time. Perform welding applications that couldn’t be done in the past.

MDX-250 MIG Gun with Bernard S Lock Consumables
Acculock S consumables feature a dual-locked, front-loading liner that optimizes wire feedability. AccuLock tips install with a single turn and the liner locks at the front and back of the gun to ensure a flawless wire feed path. Miller offers an optional MDX 250 EZ-Select MIG gun for this unit that has four LEDs on the back of the gun handle to switch between four different preset programs. This means no more trips back to the welder to make weld setting changes, i.e. increased productivity and less downtime.

Auto-Set Elite
Offers predefined weld settings to increase ease of use and ensure that the job is done right for operators of all skill levels.

Program mode allows easy save and recall of favorite weld settings.
Deliver more productivity, consistent quality by welders of all skill levels by using prequalified weld settings. Minimize supervisor need to intervene.

Auto-Line Technology
For portability and reliability this inverter power supply allows for any single-phase input voltage hookup (208–575 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.

Capabilities include MIG, pulsed MIG, Flux-Cored, DC Stick, DC LIft-Arc, and Pulsed TIG.

Portability – Machine only weighs 84 lb.
Weight is reduced by more than 50 percent compared to the Millermatic 252.
