Miller Syncrowave 400 AC/DC TIG Stick Welder – 3-400A Amp Range, P/N 951873

Displacing 400 amps through an integrated Coolmate 3.5 water cooler, the complete Miller Syncrowave 400 AC/DC TIG welder Runner package (P/N 951873) withstands non-stop aluminum deposition without torch overheating. Industrial manufacturing bays face severe downtime when air-cooled torches melt or water coolers lack the fluid capacity to dissipate high-amperage heat. This heavy Runner package combines the 400-amp Auto-Line inverter with a high-capacity Coolmate 3.5 water cooler, an industrial four-wheel running gear cart, a water-cooled torch, and a foot control pedal.

The Coolmate 3.5 high-flow pump circulates cooling fluid through torch lines continuously, keeping torch neck temperatures low during multi-pass structural weldments. Advanced AC wave controls allow you to select soft square wave for smooth puddle wetting or triangle wave for rapid heat dissipation on thin sheet metal. The heavy-duty cart features a low-profile gas bottle rack that carries two full-size shielding gas cylinders securely across factory floors.

Fabrication Stamina & Inverter Reliability

Built for high-duty-cycle aerospace, military, and naval fabrication, this water-cooled TIG station sustains continuous full-power welding shifts.

- Continuous liquid cooling prevents torch head warping, preserving gas lens sealing and stopping air-draw contamination.
- Heavy-duty rubber tires roll over metal off-cuts, extension cords, and shop floor drains without hang-ups.
- Integrated cart platform carries all cables, hoses, and gas cylinders, eliminating tangled leads around welding tables.
- Dual high-speed cooling fans protect internal inverter modules from heat breakdown during full-shift production runs.

Plate Thickness Clearance & Power Integration

The cart base measures 43 inches long by 28 inches wide, creating a mobile workstation that positions the display at natural eye height for fast adjustments.

Commercial Warranty & Preventive Maintenance

- Miller Electric backs the Syncrowave 400 powerhead and Coolmate 3.5 cooler with a 3-Year True Blue warranty.
- The industrial water-cooled TIG torch and foot remote receive 1-Year manufacturer warranty protection.

Check water cooler reservoir levels weekly with approved low-conductivity coolant, flush cooling channels annually, and clean wire drive rolls with a nylon brush.
