Pulsed TIG control 

lowers the heat input into 

the part and reduces warping and distortion
(optional on 250 DX models).

TIGRunner

system packages with 

Coolmate

3X cooler. 

A 3-gallon 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. 3-year cooler warranty.

Stick welding features such as 

Adaptive 

Hot Start

provide good arc strikes without

sticking. Once welding, the DIG control makes
dynamic adjustments to the welder to ensure
smooth E7018 and deep penetration E6010.

Tilted operator interface and built-in consumable
drawer 

provide added convenience to your

welding experience.

Arc timer/cycle counter

records actual welding

time and number of arc starts. Great for estimating
job costs.

Squarewave technology 

developed and

patented by Miller Electric in 1976. Squarewave
technology was developed to improve your weld
quality and make TIG welding easier. Miller
Squarewave technology provides arc stability
when welding aluminum, prevents arc
rectification and eliminates tungsten erosion.

Welding aluminum? 

Oxides that form on

aluminum melt at temperatures over 3700° F.
The aluminum material that is located under 
this layer of oxide melts at 1200° F. The
Syncrowave’s 

AC Squarewave welding current

automatically removes the layer of oxide which
is necessary for producing high quality welds.  

Do you have power fluctuations?

The Syncrowave compensates for power
fluctuation without changing your welding
parameters. 

Line voltage compensation

works on fluctuating power ±10%. 

NEW!

Easy Load Dual Cylinder Rack

minimizes cylinder lifting. (Cylinder not included.)
