Key Features & Performance Benefits

1. Late-Model Digital Interface Being a 2015 unit, this machine features Miller's refined digital meters and Last Procedure Recall. This allows for precise repeatability in a production environment—simply switch polarities and the machine remembers your exact amperage and balance settings.

2. Superior Aluminum Performance The Squarewave technology and AC Balance Control on this late-model DX allow you to fine-tune the arc for varying levels of aluminum oxidation. You can dial in deep penetration for heavy castings or maximum cleaning for thin, decorative sheets.

3. Industrial Build Quality At nearly 380 lbs, this machine is built with a massive copper transformer. Unlike modern light-duty inverters, the 250DX is designed to withstand fluctuating line voltage (LVC™) and the dust/debris of a busy industrial shop floor.

4. Efficiency Upgrades Features Fan-On-Demand™, which keeps the machine quiet and minimizes internal dust intake by only running the cooling system when the arc is struck and the transformer reaches temperature.
