The Miller Multimatic 235 (907780) is a robust multiprocess welding power source designed for manufacturing, MRO, and construction applications. Engineered for versatility, this machine supports MIG (GMAW), Flux-Cored (FCAW), DC Stick (SMAW), DC Lift-Arc TIG (GTAW), and Pulsed TIG processes. It operates on single-phase 240V input power and delivers a rated output of up to 235 amps, making it suitable for welding steel, stainless steel, and aluminum (with optional spool gun).
At the core of the Multimatic 235 is the Auto-Set Elite system, accessed via a 4.3-inch color LCD interface. This technology allows operators to select predefined weld settings based on material, thickness, and wire/electrode diameter, ensuring optimal parameters for every weld. For advanced users, the machine offers full manual control, including adjustable DC Pulse TIG settings (up to 150 PPS) and TIG Post-Flow control. The interface is designed to be intuitive, reducing training time and setup errors.
Efficiency is maximized through Miller's Gun-On-Demand technology. The machine features a standard MIG gun connection and a direct receptacle for Spoolmate spool guns. The system automatically detects which gun is active when the trigger is pulled, recalling the specific voltage and wire feed speed settings for that gun. This eliminates the need for manual switching or reconfiguration when moving between steel and aluminum tasks. Additionally, the unit includes dual gas solenoid valves, allowing both MIG and TIG shielding gases to remain connected simultaneously.
The unit is housed in a durable case weighing only 63 lbs (29 kg), significantly lighter than traditional transformer-based machines. It features an angled, heavy-duty aluminum two-drive-roll system that supports 12-inch wire spools, ensuring consistent feeding through the included 15-foot MDX-250 MIG gun. The MDX-250 utilizes AccuLock MDX consumables for superior arc performance and wire alignment. The Multimatic 235 is also generator compatible, requiring a generator with 10,000 watts (10 kW) or higher output for full performance.
