951000126 - Miller Syncrowave 400 AC/DC TIG Welder Complete Package 575V

Industrial Precision with the Miller Syncrowave 400

The Miller Syncrowave 400 Complete Package (575V) represents the evolution of industrial TIG welding, replacing the legendary Syncrowave 350 LX with a machine that retains the beloved arc characteristics of legacy transformer machines while utilizing energy-efficient inverter technology. Designed for heavy industrial manufacturing, maintenance, and fabrication, this 600V-class machine provides a stable, controllable arc for both AC and DC TIG welding applications, as well as Stick welding capabilities.

This "Complete" SKU (951000126) is a turnkey solution designed to minimize setup time and maximize productivity. It integrates the power source with the dedicated Coolmate™ 3S cooling system and a heavy-duty running gear. The system features Miller's Pro-Set™ technology, which eliminates guesswork by providing pre-set controls for balance, frequency, and pulse parameters, allowing operators to return to optimized settings instantly. For advanced users, the machine offers full manual control over AC Balance (60-80%) and AC Frequency (60-150 Hz), enabling precise tailoring of the arc cone and cleaning action for critical aluminum welds.

The unit operates on 575V 3-phase input power, making it suitable for Canadian industrial facilities and other high-voltage environments. The Blue Lightning™ High-Frequency (HF) arc starter ensures non-contact arc initiation for contamination-free welds, capable of starting consistently even with extended torch cable lengths. With a rated output of 300 Amps at 60% duty cycle and a range topping out at 400 Amps, the Syncrowave 400 handles thick materials with ease while maintaining the finesse required for thinner gauges.
