The Miller Millermatic® 252 MIG Welder is a high-performance, single-phase welding system engineered for industrial-strength productivity. Delivering 30–300 amps of output, it offers the power and precision required for welding 22-gauge to 1/2" steel, stainless, and aluminum. The angled cast-aluminum wire drive ensures smooth wire feeding, while Auto-Gun Detect™ automatically adjusts settings when switching between MIG or spool gun inputs — no manual setup required.

Featuring a 200/230V input and robust 60% duty cycle at 200A, the Millermatic 252 is built to handle demanding fabrication environments, repair work, and agricultural operations. Spoolmate and Spoolmatic - Direct Connect compatibility enables aluminum MIG welding with optimal arc control. — all backed by Miller’s legendary 3 Year warranty.
