The Miller Millermatic 142 MIG Welder with Cart represents the next generation of portable, 120-volt wire welding performance. Replacing the industry-standard Millermatic 141, this new inverter-based machine delivers the same trusted arc quality but in a significantly lighter and more efficient package. Weighing in at just 33 pounds (power source only), the Millermatic 142 is designed for maintenance, repair, and light fabrication environments where mobility and ease of use are paramount. This specific package (951000072) comes complete with the Miller Running Gear/Cylinder Rack, transforming the portable unit into a mobile welding station capable of holding a gas cylinder up to 7 inches in diameter.
One of the standout features of the Millermatic 142 is the enhanced Auto-Set™ technology. This breakthrough control system eliminates the guesswork often associated with setting up a MIG welder. Operators simply select the wire diameter and the material thickness, and the machine automatically configures the optimal voltage and wire feed speed. This ensures professional-quality welds for both novice users and experienced professionals who want to set up quickly. For those who prefer fine-tuning, the machine also features a segmented display and infinite voltage control, allowing for manual adjustments to the welding arc.
Despite its compact size, the Millermatic 142 is built for serious work. It operates on standard 120-volt household power, making it accessible for use in garages, body shops, and remote job sites. It boasts a high duty cycle of 60% at 100 Amps, allowing for longer welding runs without thermal shutdown. The unit is capable of welding mild steel from 24 gauge up to 3/16-inch thick in a single pass. Additionally, the Smooth-Start™ technology ensures spatter-free starts, reducing post-weld cleanup and improving overall weld appearance.
The inclusion of the heavy-duty cart makes this package a turnkey solution for shops using shielding gas. The cart features 8-inch rubber rear wheels for smooth navigation over shop floors and includes dedicated storage for cables and consumables. The welder itself features an angled cast-aluminum drive system with a calibrated tension knob for consistent wire feeding, and the Quick Select™ drive roll system allows for rapid changes between solid and flux-cored wires without the need for tools. Whether you are welding mild steel with the included MDX-100 gun or aluminum with an optional Spoolmate spool gun, the Millermatic 142 detects the connection automatically, streamlining your workflow.
