The Miller Electric Millermatic MIG Welders, Nos. 190 and 141, offer users improved ease-of-use, portability and arc performance with the ability to weld up to 5/16"-thick and 3/16"-thick material respectively in a single pass. The Millermatic 190 offers 240V of input power while the 141 offers 120V. The smaller and shorter, newly redesigned case platform features ergonomic handles that increase portability. The angled cast-aluminum drive-system with calibrated tension knob creates consistent and improved feedability, and allows for easy setup for 10', 12' and 15' MIG guns. Available on both machines, Auto Spool Gun Detect automatically detects when a MIG or spool gun is connected, eliminating the need to install a spool gun switch.
