Millermatic® 252
Welds material from 22 gauge to 1/2 in thick in a single pass. Highest output in its class (250 A at 28 VDC). Weld longer on high end applications. New! Large, digital front panel with built-in digital timers menu enables operator to preset voltage and wire feed speed. Standard run-in, pre/postflow, burnback, spot/delay (stitch) timer menu. New! Auto Gun Detect™ allows operator to simply pull trigger on MIG gun, spool gun, or push/pull gun. Automatically detects and recalls the voltage, wire feed speed, and timer of the active gun. New! Push-Pull Gun Direct Connect - now directly connects your push-pull gun, no extra module required. New! Angled, dual-gear driven, cast aluminum drive system features no-tool, quick-change reversible drive rolls and an easy-to-set, scaled tension knob. New! Patent-pending EZ-Change™ Low Cylinder Rack allows operators to easily roll cylinders on and off of rack - no need to lift cylinders. New! EZ-Access™ Consumable Compartment and Parameter Chart - set weld parameters right the first time with convenient new flip-down compartment that provides fast access to parameter chart and consumables. New! Larger work area - now with longer 15-ft M-25 gun. Less weld cleanup with Active Arc Stabilizer™
pateneted Miller design provides excellent starts proven superior to the competition. Fan-On-Demand™
coooling system operates only when needed reducing power consumption and contaminants drawn into the machine. Line voltage compensation keeps power constant even if input voltages varies by ±10%.
