Fully integrated system
System where the cooling unit runs off the power source and forms a robust and sturdy system with the integrated running gear. The machine is easy to manoeuvre and easy to position at the weld station.

Fan-On-Demand™
Power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled though the machine.

Accessibility
All interaction points with the machine and cooler can be found on the front panels. Turn the machine on from the control panel, check the flow of cooling liquid and top up if necessary, without having to move the machine and without having to access difficult to reach areas.

Wind Tunnel Technology™
Protects internal electrical components from airborne contaminants, extending the product life.

Comfort and ergonomics
The control panel of the Syncrowave is positioned at the perfect hight. Easy to access all the settings without having to kneel by the machine.

Coolmate™ 3S cooler
11 liters cooling system equipped with a visual flow indicator ensures that the coolant is flowing. An external coolant filter stops foreign objects from entering the water-cooled torch cable for better flow and longer life. Extended cooling capacity ensures maximum productivity. Threeyear cooler warranty.

Easy to use
The control panel is giving you access only to the relevant settings for the process you have selected. This keeps the panel clean and simple to understand, making it easy to adjust parameters, and means less time training new employees and more time getting work done.

Arc timer/cycle counter
Records actual welding time and number of arc starts. Great for estimating job costs.

Pro-Set™
Is a unique feature on the Miller® Syncrowave. By one touch of a button, the machine reverts to the factory pre-set parameters which will get you started in no time. Simply set the welding amperage and Go.

Welding aluminum
Oxides that form on aluminum melt at temperatures over 2000°C (3.700°F) The aluminum material that is located under this layer of oxide melts at 649°C (1.200°F) The AC squarewave welding current of the Syncrowave 300 automatically removes the layer of oxide which is necessary for producing high-quality welds.

Perfect arc starts with Blue Lightning™
By selecting the tungsten diameter, you are using, the machine will pre-set a number of critical arc start parameters. This ensure accurate and reliable arc starts every time.

Do you have power fluctuations?
The Syncrowave 300 compensates for power fluctuation without changing your welding parameters. Line voltage compensation works on fluctuating power ±10 percent.

Arc stability
The Miller brand is synonymous with world class TIG arc stability and performance. The Syncrowave is no exception. Enjoy full control of the arc and the weld puddle.

Easy-load cylinder rack
Minimizes cylinder lifting. Cylinder is not included.

AC TIG Features
Balance control provides adjustable oxide removal which is essential for creating the highest quality aluminum welds.

Lift-Arc™
Provides AC or DC arc initiation without the use of high frequency.

DC TIG Features
Pulse. Pulsing can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion.

Blue Lightning™ high-frequency
(HF) arc starter for non-contact arc initiation. Provides more consistent arc starts and greater reliability compared to traditional HF arc starters.

DC Stick Features
DIG control allows the arc characteristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth running electrodes like E7018 and increase the DIG setting for stiffer, more penetrating electrodes like E6010. Hot Start™ adaptive control provides positive arc starts without sticking.

Auto-postflow
Adjusts the length of postflow time based on the amperage setting, shielding your tungsten and eliminating the need to set the postflow time.
