The Power of Blue.  
Closed-loop design with radiator reduces  
coolant temperatures and prevents the system  
from overheating. It also recirculates the  
coolant through a fan-cooled heat exchanger.  
Standard inlet/outlet torch fittings are  
compatible with TIG and MIG torches having  
standard 5/8-18 left-hand fittings.  
Coolmate V3  
10 ft (3 m) power cords with plugs are longer  
than most power cords in the industry —  
providing the extra length when required.  
Rustproof coolant reservoir molded of poly-  
ethylene for durability and corrosion resistance.  
Thermally protected 1/4 HP motor guards  
against motor damage due to overheating.  
Positive vane-style displacement pumps  
provide consistent coolant flow and pressure  
rating with long pump-life expectancy.  
Compatible with Miller coolants and are ideal  
for warm and cold weather conditions, while  
providing HF or corrosion protection.  
Factory-preset pressure-relief valves (55 PSI)  
maintain consistent pressure during operation.  
Paddle wheel flow indicator visually confirms  
that there is coolant flowing through the system.

The Cool Runner is dedicated to any (old  
style) Syncrowave® 250 power source  
using water-cooled torches rated up to  
500 amps*. It conveniently mounts under,  
and draws 120 VAC power from the  
Syncrowave 250 to provide the perfect  
solution for industrial, water-cooled TIG  
applications. Construction details include a  
coolant reservoir and easy-to-fill coolant  
spout molded of rustproof polyethylene,  
and an efficient fin-and-tube heat exchanger.  
A paddle wheelindicator makes it easy  
to confirm that coolant is flowing, and the  
external filter can be quickly accessed for  
cleaning. To easily move the system in the  
shop, add the easy-to-install No. 22  
running gear.  
NEW! For Syncrowave 250 DX and  
350 LX. Provides the perfect solution for

Coolants  
No. 28 Running Gear #043 861  
For Cool Runner 3X. Includes two 10 in  
(254 mm) wheels and 5 in (127 mm)  
casters and a two-compartment rack for  
gas cylinder(s).  
No. 22 Running Gear #042 258  
For Cool Runner. Includes two 10 in  
(254 mm) wheels and 5 in (127 mm)  
casters and a two-compartment rack for  
gas cylinder(s).  
Low-Conductivity Coolant #043 810  
Sold in multiples of four in 1-gallon  
recyclable plastic bottles. Primarily used  
in TIG (high-frequency) applications, but  
can also be used in MIG systems where  
aluminum is not in the water path. Miller  
coolants contain a base of ethylene glycol  
and deionized water to protect against  
freezing to -37°F (-38°C) or boiling to  
227°F (108°C). Also contains a compound  
that resists algae growth.  
Aluminum-Protecting Coolant #043 809  
Sold in multiples of four in 1-gallon  
recyclable plastic bottles. Primarily used in  
MIG products, such as the water-cooled  
XR, which has an aluminum drive housing,  
or in any system where high frequency is  
not used. Miller coolants contain a base of  
ethylene glycol and deionized water to  
protect against freezing to -37°F (-38°C) or  
boiling to 227°F (108°C). Also contains a  
compound that resists algae growth.
