OVERVIEW

Comprehensive Multiprocess Welding Solution for Industrial MRO

The Miller Multimatic 255 with Dual Cylinder Running Gear and TIG Kit (951768) is a premium welding package designed for professionals in maintenance, repair, and light manufacturing. This all-in-one solution combines the power and versatility of the Multimatic 255 inverter power source with a complete set of accessories to maximize productivity right out of the box. Engineered for versatility, this machine supports MIG (GMAW), Pulsed MIG (GMAW-P), Stick (SMAW), DC Lift-Arc TIG (GTAW), and DC Pulsed TIG (GTAW-P), making it capable of handling a vast array of materials including steel, stainless steel, and aluminum (via MIG).

At the core of this system is Miller's Auto-Line technology, which allows the unit to connect to any single-phase input voltage from 208V to 575V without manual linking, ensuring reliability even in facilities with dirty or fluctuating power. The machine boasts a robust output, delivering up to 350 amps, with a rated output of 230 amps at 60% duty cycle for MIG welding. The integrated 7-inch color LCD display simplifies setup through the Auto-Set Elite feature, which automatically configures optimal parameters based on user input for material thickness and wire or tungsten diameter. For experienced operators, the interface offers full manual control and the ability to save up to four custom programs per process.

This specific package (SKU 951768) is distinguished by the inclusion of the EZ-Latch Dual Cylinder Running Gear and a complete TIG Kit. The dual cylinder rack is a critical asset for multiprocess workflows, allowing users to mount two gas cylinders simultaneously—typically one for MIG (Argon/CO2) and one for TIG (Pure Argon)—eliminating the downtime associated with swapping bottles. The TIG Kit provides all necessary components for precision DC TIG welding, including a Weldcraft WP-17 torch, RFCS-14HD remote foot control, and a dedicated regulator. Additionally, the package includes the MDX-250 MIG gun equipped with AccuLock S consumables, ensuring smooth wire feeding and superior arc stability. Weighing only 84 pounds (machine only), the unit remains portable when detached from the cart, offering flexibility for field operations.

FAQ

The Multimatic 255 features Auto-Line technology, allowing it to operate on any single-phase input voltage from 208 V to 575 V without manual linking.

Yes, this package (951768) includes the Multimatic 255 TIG Kit, which comes with a 25-foot Weldcraft WP-17 TIG torch, a foot control, and other accessories.

Yes, it can weld aluminum using the MIG process with a push-pull gun or spool gun. However, it cannot TIG weld aluminum because it is a DC-only machine (aluminum TIG requires AC).

The dual cylinder rack allows you to mount two gas cylinders at once, such as one for MIG and one for TIG, enabling rapid switching between processes without changing gas bottles.

The rated output for MIG welding is 230 Amps at 25.5 Volts with a 60% duty cycle.

Yes, the Multimatic 255 has built-in Pulsed MIG capabilities, which helps reduce spatter and heat input, making it excellent for thin materials.

To achieve full output, a generator with 12,000 Watts (12 kW) or higher is recommended.

The machine itself weighs 84 lbs (38 kg), making it relatively portable compared to older transformer-based machines.
